Moeller 730098 GW29 29-Gallon Gas Walker Fuel Caddy
Moeller 730098 GW29 29-Gallon Gas Walker Fuel Caddy — Product description
The Moeller 730098 GW29 Gas Walker (MPN 730098, UPC 739729018187) is a 29-gallon portable fuel caddy for transporting gasoline, diesel, or kerosene to fuel boats, equipment, and machinery in locations where direct fuel pump access isn't available. The Gas Walker line is the standard reference solution for marina fuel transfer operations, marine equipment refueling, and any situation requiring portable bulk fuel handling beyond what gas can capacity allows. The 29-gallon capacity is the larger of the two Gas Walker sizes (the smaller GW14 holds 14 gallons) - sized for serious fuel transfer where a single trip to the fuel pump fills enough fuel to top off a typical boat, fuel multiple pieces of equipment, or refill a remote stationary tank. Durable cross-linked polyethylene tank construction with UV inhibitors - the right material choice for fuel storage in outdoor / marina environments. Cross-linked polyethylene is more chemically resistant than standard polyethylene (handles fuel without softening or chemical breakdown over years of service), the UV inhibitors prevent the typical degradation from sun exposure that plagues standard plastic fuel containers. Built-in 3-1/2 GPM gravity feed flow rate - position the GW29 above your fueling point (typical boat fuel fill, equipment tank) and gravity moves fuel from the GW29 to the receiving tank at 3.5 gallons per minute. No pumping required for gravity-feed applications. For applications where gravity feed isn't practical (level transfer, uphill transfer, or applications requiring faster flow), the optional Moeller 730090 rotary hand pump (sold separately) bumps flow to approximately 7-1/2 GPM. Bundle includes 10 feet of 3/4 inch fuel transfer hose with a nozzle for direct refueling - long enough for typical boat fueling scenarios from the marina dock to the boat fuel fill. Brass shut-off valve controls fuel flow at the tank outlet. Locking plate prevents accidental fuel discharge during transit and theft of fuel from the tank. Electric static discharge grounding wire is the critical safety component that prevents static electrical buildup during fuel transfer (which can ignite gasoline vapors). Safe for gasoline, diesel, AND kerosene - but do NOT mix fuels in the same tank between uses. Meets US DOT requirements for gasoline transport. 63 lb shipping weight (empty tank). The GW29 is the standard solution for serious fuel transfer in marinas, boatyards, equipment rental operations, and commercial fishing applications.
The Moeller GW29 Gas Walker is a 29-gallon portable fuel caddy for transporting gasoline, diesel, or kerosene to fuel boats, equipment, and machinery in locations where direct fuel pump access isn't available. The Gas Walker line is the standard reference solution for marina fuel transfer operations and any situation requiring portable bulk fuel handling beyond gas can capacity.
What this thing is for. Several practical fuel-handling scenarios require more capacity and better dispensing than the typical 5-gallon gas can: (1) Marina fueling - boat in a slip without a fuel dock, or on a mooring buoy away from the pump. Hauling 5-gallon cans for a 30-gallon top-off requires 6 round trips. The GW29 does it in one. (2) Equipment refueling at remote locations - generators, pumps, irrigation equipment, agricultural machinery far from the nearest fuel pump. (3) Tournament fishing fuel transport - bringing extra fuel to remote launching sites for long-running tournament days. (4) Commercial fishing pre-trip fueling - transferring fuel from bulk storage to multiple boats before a trip. (5) Boatyard work - transferring fuel during maintenance, hull moves, or repair work where the boat can't access the fuel pump directly. The GW29 handles all of these with one trip per 29 gallons - dramatically more efficient than gas can shuttle operations.
Cross-linked polyethylene tank. The tank is cross-linked polyethylene (commonly called 'XLPE' or 'XL-poly') rather than standard polyethylene. The difference matters for fuel applications: cross-linked polyethylene is chemically more resistant than standard polyethylene to fuel-induced softening, chemical breakdown, and degradation. Standard polyethylene fuel containers eventually develop fuel sweat (slight weeping of fuel through the container walls), become brittle from chemical exposure, and crack from internal pressure changes. Cross-linked polyethylene resists all of these failure modes - the tank stays strong, sealed, and dimensionally stable for years of service. UV inhibitors prevent the typical sun-exposure degradation that plagues standard plastic fuel containers in outdoor / marina environments.
29 gallon capacity. The larger of the two Gas Walker sizes (GW14 holds 14 gallons). Practical translation: 29 gallons of gasoline weighs roughly 175 pounds, plus the 63 lb empty tank weight = 238 pounds total when full. The GW29 is designed for transport on a marina cart, hand truck, or built-in marina fuel transfer cart - it's NOT a hand-carry container at full capacity. For pure hand-carry applications, the smaller GW14 is more manageable. For marina cart / hand truck transport where weight isn't the limiting factor, the GW29 minimizes trip count to the fuel pump.
3-1/2 GPM gravity feed. The built-in gravity feed delivers fuel at 3.5 gallons per minute when the GW29 is positioned above the receiving tank. Position the GW29 on a marina dock, equipment platform, or tank-top mounting, run the included 10 ft hose down to the receiving tank's fill port, open the brass shut-off valve, and gravity does the work. 29 gallons transfer in about 8-9 minutes at the gravity feed rate. For most applications, gravity feed is the right choice - simple, no pumping effort, reliable. For applications where gravity feed isn't practical (level transfer, uphill transfer, or applications requiring faster flow), the optional Moeller 730090 rotary hand pump (sold separately) bumps flow to approximately 7-1/2 GPM and works in any tank orientation.
10 ft of 3/4 inch hose with nozzle. The bundle includes 10 feet of 3/4 inch fuel transfer hose with a fueling nozzle - sufficient for typical boat fueling scenarios from marina dock to boat fuel fill, or equipment refueling at typical setup distances. The hose is fuel-rated for gasoline, diesel, and kerosene. The nozzle includes the standard control trigger for starting and stopping fuel flow during dispensing. For applications requiring longer hose reach, fuel-rated hose extensions are widely available at marine supply or industrial supply stores.
Brass shut-off valve. A brass shut-off valve at the tank outlet controls fuel flow into the hose. Open the valve to allow fuel transfer, close it to stop. Brass is the right material choice for fuel valve service - chemically resistant to fuel and corrosion-resistant in marine environments. The valve provides positive shut-off without relying on the nozzle's trigger - if the nozzle trigger fails or accidentally activates, the brass valve at the tank prevents fuel discharge.
Locking plate. The Gas Walker includes a locking plate that secures the valve and hose during transit and at rest. Two practical benefits: (1) Prevents accidental fuel discharge during transport - if the GW29 tips during transit, the locked valve can't accidentally open and dump fuel. (2) Prevents theft of fuel from the tank - the lock plate accepts a padlock so unauthorized persons can't access the valve and drain the tank. Critical for marinas, boatyards, and equipment storage areas where unattended fuel containers are theft targets.
Electric static discharge grounding wire. This is the most important safety component on any fuel transfer container. Fuel transfer generates static electricity (the friction of fuel flowing through the hose builds electrical charge on the fuel and on the container surfaces). Without proper grounding, the static charge can build up to dangerous levels and discharge as a spark - which ignites gasoline vapors and causes fuel fires / explosions. The grounding wire attaches to a known ground (the boat hull, equipment chassis, or marina ground point) before fuel transfer begins, providing a path for static charges to dissipate safely. ALWAYS connect the grounding wire before starting fuel transfer. Skipping this step has caused fatal fuel fires - the static discharge can occur even on calm dry days.
Fuel compatibility. The GW29 is rated safe for gasoline, diesel, AND kerosene. The tank materials and seals handle all three fuels without degradation. CRITICAL: do NOT mix fuels in the same tank between uses. If you transport gasoline today and need to transfer diesel tomorrow, the residual gasoline in the tank will contaminate the diesel - resulting in fuel-quality issues that can damage diesel engines. Dedicate the GW29 to one fuel type and stick with it. If you need to transfer multiple fuel types, use separate tanks for each.
US DOT compliance. The GW29 meets US DOT requirements for transporting gasoline by road - the construction, labeling, and venting meet the federal safety standards for fuel transport in commercial and private vehicles. You can legally transport the full GW29 in a car, truck, or trailer on US public roads, subject to state-specific regulations for the maximum quantity transported. Check your state regulations before transporting large fuel quantities.
Safety practices. Several practical safety rules for any fuel caddy operation: (1) ALWAYS connect the grounding wire before starting fuel transfer. Static ignition is the most common cause of fuel transfer fires. (2) Never operate the GW29 near open flames, sparks, or smoking. (3) Position the GW29 on stable ground or a solid platform during transfer - tipping during transfer can spill fuel and cause fire. (4) Use the GW29 outdoors or in well-ventilated areas only - never in confined spaces where fuel vapors can accumulate. (5) Check the tank, hose, and valve for damage before each use - replace any damaged components immediately. (6) Store the GW29 with the valve closed and locked when not in use.
Warranty. Moeller standard limited warranty applies. Save the receipt and the original packaging. Warranty service runs through Moeller's authorized service network. Most field failures Moeller sees in the Gas Walker line are damage-related (impact damage from drops or transit accidents) rather than manufacturing defects - careful handling delivers many years of service. Replacement parts (hoses, nozzles, valves) are widely available from Moeller and aftermarket suppliers.

Frequently asked questions
What's the difference between GW29 and GW14?
Capacity. The GW29 holds 29 gallons, the GW14 holds 14 gallons - both use the same Gas Walker design and construction, just different tank sizes. Pick based on your use case: GW14 for hand-carry applications where the full container weight must be manageable (14 gal gasoline = roughly 88 lb plus tank = around 130 lb total - challenging but possible for a strong person). GW29 for marina cart / hand truck / vehicle transport where you minimize trip count to the fuel pump (29 gal gasoline = roughly 175 lb plus 63 lb tank = around 238 lb total - NOT a hand-carry container at full capacity). For marina operations where you have a cart or hand truck available, the GW29 is more efficient. For pure hand-carry, the GW14 is more practical.
Can I use it for both gasoline and diesel?
Technically yes - the GW29 is rated safe for gasoline, diesel, AND kerosene. The tank materials and seals handle all three fuels without degradation. CRITICAL: do NOT mix fuels in the same tank between uses. If you transport gasoline today and need to transfer diesel tomorrow, the residual gasoline in the tank will contaminate the diesel - resulting in fuel-quality issues that can damage diesel engines. Dedicate the GW29 to one fuel type and stick with it. If you need to transfer multiple fuel types, use separate tanks for each. Many marina operators have one Gas Walker dedicated to gasoline and another dedicated to diesel.
How fast does it transfer fuel?
3-1/2 GPM gravity feed flow rate. 29 gallons transfers in roughly 8-9 minutes at the gravity feed rate. For applications where gravity feed isn't practical (level transfer, uphill transfer, or applications requiring faster flow), the optional Moeller 730090 rotary hand pump (sold separately) bumps flow to approximately 7-1/2 GPM and works in any tank orientation. The hand pump completes a 29-gallon transfer in 4-5 minutes vs 8-9 minutes for gravity feed. For most marina applications, gravity feed is the right choice - simple, no pumping effort, reliable.
Why is the grounding wire so important?
Fuel transfer generates static electricity (the friction of fuel flowing through the hose builds electrical charge on the fuel and on the container surfaces). Without proper grounding, the static charge can build up to dangerous levels and discharge as a spark - which ignites gasoline vapors and causes fuel fires / explosions. The grounding wire attaches to a known ground (the boat hull, equipment chassis, or marina ground point) before fuel transfer begins, providing a path for static charges to dissipate safely. ALWAYS connect the grounding wire before starting fuel transfer. Skipping this step has caused fatal fuel fires - the static discharge can occur even on calm dry days. This is the most important safety practice for any fuel transfer operation.
What's the lock plate for?
The locking plate secures the brass valve and hose during transit and at rest. Two practical benefits: (1) Prevents accidental fuel discharge during transport - if the GW29 tips during transit, the locked valve can't accidentally open and dump fuel. (2) Prevents theft of fuel from the tank - the lock plate accepts a padlock so unauthorized persons can't access the valve and drain the tank. Critical for marinas, boatyards, and equipment storage areas where unattended fuel containers are theft targets. Use a padlock rated for outdoor / marine service to prevent the lock itself from corroding.
How heavy is it when full?
29 gallons of gasoline weighs roughly 175 pounds, plus the 63 lb empty tank weight = 238 pounds total when full. Diesel is slightly heavier per gallon (about 7 lb/gal vs 6 lb/gal for gasoline) - 29 gallons of diesel weighs about 203 lb, total 266 lb full. The GW29 is designed for transport on a marina cart, hand truck, or built-in marina fuel transfer cart - it's NOT a hand-carry container at full capacity. For pure hand-carry applications, the smaller GW14 is more manageable. For marina cart / hand truck transport where weight isn't the limiting factor, the GW29 minimizes trip count to the fuel pump.
Is it legal to transport on public roads?
Yes - the GW29 meets US DOT requirements for transporting gasoline by road. The construction, labeling, and venting meet the federal safety standards for fuel transport in commercial and private vehicles. You can legally transport the full GW29 in a car, truck, or trailer on US public roads, subject to state-specific regulations for the maximum quantity transported. Check your state regulations before transporting large fuel quantities. Most states allow private transport of fuel quantities up to certain limits (often 50-100 gallons) for personal use without commercial fuel transport licenses.
Why XLPE instead of standard polyethylene?
Cross-linked polyethylene (XLPE) is chemically more resistant than standard polyethylene to fuel-induced softening, chemical breakdown, and degradation. Standard polyethylene fuel containers eventually develop fuel sweat (slight weeping of fuel through the container walls), become brittle from chemical exposure, and crack from internal pressure changes. Cross-linked polyethylene resists all of these failure modes - the tank stays strong, sealed, and dimensionally stable for years of service. UV inhibitors prevent the typical sun-exposure degradation that plagues standard plastic fuel containers in outdoor / marina environments. The XLPE construction is what makes the Gas Walker a serious long-term fuel transfer solution vs cheap fuel container alternatives.
What safety practices should I follow?
Several practical rules: (1) ALWAYS connect the grounding wire before starting fuel transfer. Static ignition is the most common cause of fuel transfer fires. (2) Never operate the GW29 near open flames, sparks, or smoking. (3) Position the GW29 on stable ground or a solid platform during transfer - tipping during transfer can spill fuel and cause fire. (4) Use outdoors or in well-ventilated areas only - never in confined spaces where fuel vapors can accumulate. (5) Check the tank, hose, and valve for damage before each use - replace any damaged components immediately. (6) Store the GW29 with the valve closed and locked when not in use.
How long is the hose?
10 feet of 3/4 inch fuel transfer hose included with the bundle. Sufficient for typical boat fueling scenarios from marina dock to boat fuel fill, or equipment refueling at typical setup distances. The hose is fuel-rated for gasoline, diesel, and kerosene. For applications requiring longer hose reach (fueling boats moored away from the dock, fueling equipment at significant distance from the caddy position), fuel-rated hose extensions are widely available at marine supply or industrial supply stores. Use only fuel-rated hose for extensions - standard garden hose or industrial hose isn't safe for fuel service.
Should I get the optional pump?
Depends on your use case. For gravity-feed applications (caddy elevated above the receiving tank), the included gravity feed is fine - 3.5 GPM flow rate, no pump cost. For applications where gravity feed isn't practical (caddy level with or below the receiving tank, or applications requiring faster flow), the optional Moeller 730090 rotary hand pump (sold separately) bumps flow to approximately 7-1/2 GPM and works in any tank orientation. The pump completes a 29-gallon transfer in 4-5 minutes vs 8-9 minutes for gravity feed. For marina operators who fuel boats in slips at water level (where gravity feed from the dock is fine), the pump isn't needed. For users who need flexible transfer geometry, the pump is worthwhile.
What's the warranty?
Moeller standard limited warranty applies. Save the receipt and the original packaging. Warranty service runs through Moeller's authorized service network. Most field failures Moeller sees in the Gas Walker line are damage-related (impact damage from drops or transit accidents) rather than manufacturing defects - careful handling delivers many years of service. Replacement parts (hoses, nozzles, valves) are widely available from Moeller and aftermarket suppliers - the Gas Walker is designed for serviceability with standard replaceable components.
