Moose Offroad — Eliminating Fuel Starvation, Restore Your Top-End Scream

Is your Yamaha struggling to start, bogging under heavy load, or popping at high RPMs? These are classic symptoms of a failing fuel pump. Instead of spending hundreds on a complete housing assembly, the Moose Offroad 1009-0094 Fuel Pump Rebuild Kit allows you to fix the problem at the source. This kit identifies the common pain point of fuel pressure drop-off and provides a high-performance solution to ensure your fuel injection system maintains the precise PSI required for aggressive motocross and off-road riding.

Engineered to meet Factory Quality standards, this kit includes the pump, internal filters, and necessary hardware to refresh your existing fuel module. Every component is designed to withstand the corrosive properties of modern ethanol-blended fuels, preventing premature swelling or failure. By restoring proper fuel flow to your Yamaha YZ250F or YZ450F, you ensure consistent throttle response and protect your engine from lean-condition damage during long motos.

• Complete Rebuild Solution: Includes all internal components to refresh the OEM fuel pump module.
• Cost-Effective Performance: Restores full fuel pressure without the expense of a total housing replacement.
• Ethanol Resistant: Materials chosen specifically to handle modern pump gas and race fuel additives.
• Direct Fitment: Plug-and-play internal components ensure a hassle-free installation process.
• Optimized Flow Rate: Matches factory specifications to maintain correct air-fuel ratios across the powerband.

Moto-House MX Pro Tip:

When rebuilding your Yamaha fuel pump module, cleanliness is vital. Before opening the fuel tank, wash the area thoroughly to prevent dirt from falling into the tank. Once the module is out, use a dedicated contact cleaner to rinse the internal housing before installing the new Moose Offroad components. A tiny grain of sand can ruin a brand new pump and clog your fuel injector, so take your time and keep your workspace pristine.
