Fuel Pump

Excellent. Exact replacement. Works great. Different noise than the Warlboro it replaced and the supplied insulation makes it quieter than before.

Quantum Fuel pump

I put a Quantum Fuel Pump in before a 2 week, 8600 mile trip to Alaska. You have an excellent product that will put up with the rough roads there and back. Bike great!! I definitely recommend your Fuel pumps.
