• Durability Built for Boating: Sealed housing protects against moisture, ethanol-blended fuels, and debris, extending service life in harsh marine settings.
• Direct Cross-Reference to JV385765: Plug-and-play fit for seamless upgrades without custom modifications.
• Enhanced Diaphragm Technology: Self-priming mechanism pulls fuel effortlessly, even from low tanks or after long periods of storage.

These aren't just specs—they translate to fewer trips back to the dock and more time enjoying the ride. Real-world testing shows it outperforms generics in flow rate consistency, especially at wide-open throttle.

Perfect Fit for Popular Outboard Engines

This fuel pump is tailored for a range of two-stroke and four-stroke outboards from leading brands. It slots right into models requiring JV385765 specs, ensuring compatibility without adapters or hassle. Common applications include mid-range horsepower engines where fuel delivery is critical for smooth operation across RPM ranges.

Before installing, double-check your engine's service manual for exact fitment. It's a favorite among weekend warriors and charter captains alike for its versatility in freshwater and offshore setups.

Step-by-Step Installation Guide for DIY Boaters

Swapping out your old pump is straightforward with basic tools—no marine mechanic required. Here's a proven process:

1. Disconnect the battery and relieve fuel system pressure by pinching the primer bulb.
2. Locate the pump (usually inline near the tank or engine block) and clamp fuel lines to prevent spills.
3. Remove electrical connectors and mounting bolts, then detach hoses carefully.
4. Install the new Sierra 18-7330, using new gaskets or O-rings for leak-free seals. Torque to spec—typically 10-15 ft-lbs.
5. Reconnect everything, prime the system, and test for leaks at idle before full throttle.

Pro tip: Flush the fuel lines first if your old pump was clogged with varnish from stale gas. This simple swap often takes under an hour and saves hundreds in shop labor.

Maintenance Tips to Maximize Longevity

To keep your Sierra 18-7330 running strong season after season:

• Use fuel stabilizers during storage to prevent gum-up from ethanol fuels.
• Inspect hoses and filters annually—clogged inlines starve the pump.
• Monitor voltage at the pump; low battery output causes premature wear.
• Winterize properly by running the engine with treated fuel to clear lines.

Regular care like this can double the pump's lifespan, turning a one-season fix into years of trouble-free boating.
