Sierra 18-7928-1 79281 Fuel/Water Separator Element w/AquaVue Clear Collection Bowl Product Description
Keeping your boat's engine running smoothly starts with crystal-clear fuel. In the harsh marine world, where water sneaks into tanks from condensation, rain, or sloppy fueling, a top-notch fuel/water separator is your first line of defense. The Sierra 18-7928-1 element paired with the AquaVue clear collection bowl steps up to tackle this head-on, trapping contaminants and letting you drain water effortlessly to safeguard your outboard or inboard powerplant.
Why This Fuel/Water Separator Stands Out on the Water
Boat owners know the frustration of a stalled motor mid-trip because of contaminated fuel. This setup changes that by combining a high-efficiency filter media that captures dirt, rust, and microscopic water droplets with a transparent bowl that gives you a real-time view of what's collecting below. No more guesswork—spot issues early and act fast.
Core Features That Deliver Real-World Reliability
- Superior Water Separation: Advanced coalescing technology pulls free water from diesel or gasoline, allowing simple drain-down to prolong filter life and protect injectors or carburetors.
- AquaVue Clear Bowl Design: Perfect for outboard motors and above-deck installs, the see-through polyethylene lets you monitor water levels without disassembly. It's tough against UV rays and impacts common in boating.
- Regulatory Compliance Ready: For below-deck applications, switch to the flame-resistant metal bowl option to meet USCG fire safety standards—essential for peace of mind on inland or coastal runs.
- Drop-In Compatibility: Engineered as a precise aftermarket fit for popular marine setups, minimizing downtime during swaps.
Boost Your Boating Experience: Performance and Protection
Imagine smoother acceleration, fewer corrosion headaches, and engines that hum longer without the corrosion creep from emulsified fuel. By routinely draining collected water—often just a quick petcock twist—you cut service intervals and slash repair bills. Saltwater anglers, weekend cruisers, or tournament pros all benefit from this setup's ability to handle humid docks, choppy seas, and variable fuel quality at marinas.
Pro Tips for Installation and Daily Use
- Shut off fuel supply and relieve pressure before swapping elements to avoid messy spills.
- Prime the system post-install by cycling the bulb or electric pump until fuel flows clean.
- Check the clear bowl weekly during peak season; drain if water hits the halfway mark.
- Pair with a quality fuel stabilizer for off-season storage to fight internal tank moisture.
Users rave about how this combo transforms fuel system maintenance from a chore into a 5-minute ritual, keeping adventures interruption-free.
Frequently Asked Questions
What makes a fuel/water separator essential for marine engines?
Marine fuel often picks up water from humidity or poor storage, leading to phase separation in gas or injector damage in diesels. This separator isolates water, preventing it from reaching your engine and causing breakdowns or long-term wear.
When should I use the AquaVue clear bowl versus a metal one?
Opt for the AquaVue clear bowl on outboards or above-deck spots for easy visual checks. Below deck, USCG rules mandate the flame-resistant metal bowl to reduce fire risk in engine compartments.
How often do I need to drain water from the separator?
Inspect weekly or before long trips. Drain whenever water accumulates visibly—typically every 50-100 hours of runtime, depending on conditions like heavy rain or saltwater exposure.
Can this element handle both gasoline and diesel boats?
Yes, it's versatile for gas outboards and some diesel setups, efficiently separating water across fuel types while filtering particulates down to 10 microns.
Does replacing the element extend my engine's life?
Absolutely. Clean, water-free fuel reduces corrosion, improves combustion, and prevents costly issues like stuck floats or scored cylinders, often adding seasons of reliable service.
What's the easiest way to tell if the filter element needs replacing?
Watch for sluggish starts, power loss, or dark residue in drained water. Replace every 200 hours or annually, or sooner if fuel quality is suspect.
Is this a direct replacement for OEM filters?
Sierra designs these as OEM-spec alternatives, matching flow rates and mounting for seamless installs on a range of popular boat engines without modifications.
Equip your vessel with this proven fuel/water separator and focus on the horizon, not the fuel line. Reliable performance awaits.
AquaVue™ Clear Bowls: Use for outboard and above deck installations.
Metal Bowl Collection: USCG regulations require the use of flame resistant metal bowls below deck.
