Sierra 18-80010 80010 Suzuki VST Filter

Keep your Suzuki outboard running smoothly on the water with the Sierra 18-80010 VST filter, a reliable aftermarket solution designed specifically for fuel system integrity. This filter traps contaminants, water, and debris before they can damage sensitive engine components, ensuring consistent performance during long days of boating, fishing, or cruising. Boat owners trust Sierra parts for their durability and precise fit, making routine maintenance straightforward without compromising on quality.

Understanding the VST Filter's Role in Your Suzuki Outboard

The Vapor Separator Tank (VST) filter sits at the heart of your Suzuki's fuel delivery system, separating fuel vapors from liquid fuel while filtering out impurities. Over time, exposure to ethanol-blended fuels, saltwater environments, and normal wear leads to clogging, which can cause hard starting, hesitation under load, or even stalling mid-run. Replacing it proactively prevents these headaches and extends the life of your injectors and high-pressure pump.

Unlike basic inline filters, the VST filter handles higher flow rates and pressures unique to modern four-stroke outboards. Opting for a high-quality replacement like the Sierra 18-80010 means peace of mind—it's engineered to match OEM specifications for filtration efficiency and flow, but built tougher for marine conditions.

Key Features and Performance Advantages

• Precision Filtration: Captures particles as small as 10 microns, protecting downstream components from wear.
• Corrosion-Resistant Construction: Materials withstand ethanol fuels and harsh marine atmospheres.
• Direct OEM Replacement: Matches the form, fit, and function of factory parts for hassle-free installation.
• Enhanced Durability: High-capacity media holds more contaminants before restricting flow, ideal for extended outings.
• Easy Visual Inspection: Clear housing options on compatible setups allow quick checks during service.

Users report noticeable improvements in throttle response and fuel economy after installation, especially on boats stored in humid climates where water contamination is common.

Compatibility with Suzuki Outboards

This Sierra VST filter fits a wide range of Suzuki four-stroke models, including popular DF series from 40hp to 300hp. It's a drop-in replacement for OEM part 80010, commonly found on engines like the DF150, DF200, DF225, DF250, and DF300. Always cross-reference your engine's serial number to confirm fitment, as variations exist across model years. Perfect for both recreational and commercial applications, from center consoles to offshore sportfishers.

Simple Installation Steps for DIY Mechanics

Swapping out your VST filter takes about 30-45 minutes with basic tools—no special equipment required. Here's a quick guide:

1. Run the engine until fuel pressure drops, then shut off and relieve system pressure per your manual.
2. Disconnect the battery and locate the VST unit (typically near the fuel tank or mid-engine).
3. Unclip or unscrew the old filter housing, drain any residual fuel, and remove the filter element.
4. Install the new Sierra 18-80010, ensuring proper orientation and seals.
5. Reassemble, prime the system, and test for leaks before heading out.

Pro tip: Inspect fuel lines and the VST tank for buildup during replacement to catch issues early.

Maintenance Best Practices to Maximize Engine Life

Inspect your VST filter every 100 hours or annually, whichever comes first. Signs it's time for replacement include rough idling, loss of top-end speed, or fuel smell from the exhaust. Pair this filter with fresh fuel stabilizers and water-separating filters for optimal protection. In salty environments, rinse the exterior with freshwater after use to prevent corrosion creep.

Regular service like this not only boosts reliability but can improve fuel efficiency by up to 10%, keeping more money in your pocket for adventures on the water.
