Review on 💪 Enhance Performance with Walbro GSL392-400-939 High Pressure Inline Fuel Pump: Universal External Pump, 255LPH by Sean Young

Pump failed after one ride. Even with the fuel system shut off, this only pumped up to 45psi at idle, and when the throttle was pushed hard it dropped to zero. Sent the first one back in May and am still waiting for a refund. The seller did not respond to my contact request. December Edit: Still no credit on my account due to the return of the first pump. Pretty mad at that. The second pump I ordered has already done 500 miles and works well with my 600hp Fitech power boost system.
