Sierra 18-79913 79913 Fuel/Water Separator Kit W/Collection Bowl Product Description

Keep your boat's engine running smoothly even in rough waters with a reliable fuel/water separator kit designed for marine enthusiasts who demand performance and safety. Water contamination in fuel is a common headache for boaters, leading to corrosion, injector issues, and unexpected breakdowns. This kit tackles that head-on by efficiently trapping water while allowing easy drainage, so you spend more time on the water and less in the shop.

Key Features That Stand Out

  • Effective Water Separation: The advanced filter media captures water droplets from fuel, letting you drain them manually to prolong filter life and protect your engine from costly damage.
  • Versatile Bowl Options: Choose AquaVue™ clear bowls for easy visual checks during outboard or above-deck setups, or opt for durable metal collection bowls that meet strict USCG flame-resistant standards for below-deck installations.
  • Robust Construction: Built to withstand the harsh marine environment, with corrosion-resistant materials that ensure long-term reliability season after season.

Why Boaters Trust This Setup

Imagine heading out for a weekend cruise, only to have your engine sputter because of emulsified fuel from yesterday's rain. A quality fuel/water separator changes the game by coalescing water into separable droplets, preventing it from reaching critical components like carburetors or fuel pumps. Regular draining not only extends the filter's service interval but also gives you peace of mind—spot potential issues early through the transparent bowl or reliable metal design. It's a small maintenance ritual that saves big on repairs.

Pro Tips for Peak Performance

Install this kit inline with your fuel line for optimal flow—most setups handle up to 60 GPH without restricting power. Check the collection bowl weekly, especially after heavy rain or extended storage, and drain any accumulated water by loosening the petcock valve. Pair it with fresh, ethanol-free fuel for even better results, as ethanol tends to attract moisture. If you're retrofitting an older outboard, ensure proper priming to avoid air locks during the initial startup.

Real-World Reliability

From coastal fishing trips to offshore adventures, this separator has proven itself in diverse conditions. The clear bowl lets you gauge water levels at a glance without disassembly, while the metal version adds that extra layer of safety compliance for enclosed engine compartments. It's not just a filter; it's your first line of defense against fuel-related downtime.

Frequently Asked Questions

How often should I drain the water from the collection bowl?

Drain the bowl weekly or after every few outings, especially if you've noticed condensation or used the boat in humid conditions. A quick visual check through the clear bowl makes this effortless.

What's the difference between the AquaVue clear bowl and the metal bowl?

AquaVue clear bowls are ideal for outboard and above-deck use, offering easy visibility of water levels. Metal bowls are flame-resistant and required by USCG regulations for below-deck applications where fire safety is paramount.

Can this kit handle high-performance engines?

Yes, it's engineered for typical marine outboards and sterndrives with fuel flows up to common recreational levels, ensuring no power loss while separating water effectively.

What are the signs that my fuel has water contamination?

Look for hard starting, rough idling, or white smoke from the exhaust. Accumulating water in the separator bowl confirms the issue before it hits your engine.

Is installation straightforward for DIY boaters?

Absolutely—most installs take under an hour with basic tools. Mount securely, connect fuel lines with proper clamps, and prime the system to get back on the water fast.

How does this extend the life of my fuel filter?

By removing water before it mixes with fuel, it prevents the filter from clogging prematurely, often doubling service intervals compared to standard filters.

Filters allow water to be drained from the filter to extend sevice life.
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.
