Sierra 18-79914 79914 Fuel/Water Separator Kit W/Collection Bowl Product Description

Enhance Your Boat's Fuel System Reliability

Keeping water out of your marine engine's fuel is crucial for smooth performance and longevity. This fuel/water separator kit captures and drains water before it reaches sensitive components, preventing corrosion, injector damage, and costly breakdowns on the water. Designed for easy integration into outboard and sterndrive setups, it combines robust filtration with user-friendly collection options tailored to your installation location.

Smart Water Drainage for Extended Filter Life

The integrated filter media efficiently traps water droplets while allowing clean fuel to pass through. A simple drain valve lets you empty collected water during routine checks, maximizing the filter's service intervals and reducing maintenance downtime. Boaters report fewer engine hesitations and stalls after switching to this setup, especially in humid coastal environments or after heavy rain.

Choose the Right Bowl for Your Deck Setup

  • AquaVue Clear Bowls: Ideal for outboard motors and above-deck mounts. The transparent design provides instant visual inspection—no tools needed to check water levels. Spot sediment or water buildup at a glance and drain it effortlessly before it becomes an issue.
  • Metal Bowl Collection: Built for below-deck applications where safety standards demand it. These flame-resistant metal bowls comply with USCG regulations, offering durable protection in engine compartments. Heavy-duty construction withstands vibration and heat without cracking.

Selecting the appropriate bowl ensures optimal visibility or regulatory compliance without compromising on performance. Many users appreciate the versatility, swapping bowls as needed for different vessels or seasonal storage.

Effortless Installation and Ongoing Care

Drop-in compatibility makes setup straightforward—most installations take under an hour with basic tools. Position the unit in-line with your fuel line, secure the mounting bracket, and connect the hoses. Pro tip: Install a shut-off valve upstream for safer servicing.

Maintenance Best Practices

  1. Inspect weekly during peak season; drain water if the bowl shows more than 1/4 full.
  2. Replace the filter element every 100 hours or annually, whichever comes first.
  3. Flush the system with clean fuel after storage to clear any residues.
  4. Monitor for milky fuel lines, a telltale sign of emulsified water needing immediate attention.

These steps keep your engine running like new, avoiding the frustration of waterlogged fuel pumps mid-trip.

Why This Kit Stands Out for Marine Enthusiasts

Beyond basic filtration, this kit prioritizes real-world boating needs. Its corrosion-resistant materials handle saltwater exposure, while the collection bowl design minimizes spills during drainage. Trusted by weekend warriors and charter captains alike, it delivers peace of mind whether you're trolling for fish or crossing open bays. Upgrade from stock filters prone to clogging and embrace a cleaner, more dependable fuel path.

Frequently Asked Questions

What does a fuel/water separator do for my boat?

It removes water and contaminants from fuel before they reach the engine, preventing damage like corrosion or poor combustion. Regular draining extends filter life and ensures reliable starts.

When should I use the clear AquaVue bowl versus the metal bowl?

Clear bowls suit above-deck or outboard installs for easy visual checks. Metal bowls are required below deck per USCG rules for flame resistance in enclosed spaces.

How often do I need to drain the collection bowl?

Check weekly or after every few outings. Drain when water reaches about 25% capacity to avoid overflow and maintain efficiency.

Is this kit suitable for all outboard motors?

It's designed for common marine fuel systems with standard 10-micron filtration needs. Verify hose and mount compatibility for your setup.

Can water in fuel damage my engine?

Yes—water causes rust in injectors, fuel pumps, and carbs, leading to stalls, rough idling, or total failure. Proactive separation avoids these headaches.

How do I know if my filter needs replacing?

Signs include reduced power, frequent water draining, or visible debris. Follow the 100-hour or annual replacement guideline for best results.

Does this kit help in saltwater environments?

Absolutely. Corrosion-resistant components and effective water separation combat condensation and spray common in marine use.

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.
