    1150GS Noisy Fuel Pump

    Hello MOA,

    I recently had an Enduralast 43mm Fuel pump kit installed in my '02 GS. The original set up was a mess (disintegrated rubber hoses floating in the tank etc). I had the new kit installed by a local BMW dealer. The shop is reputable, and from my experience they do good work. Iím confident everything was done correctly. There was a turbine-like whine coming from the new fuel pump after install. You could hear it over the motor. EME was awesome and sent me a replacement. The new one was as loud the original. It sounds like a table-saw.

    - The pump sound is consistent. It doesnít change pitch as I ride.

    - The throttle response is snappy and smooth. The motor doesnít seem to be fuel starved. It felt fantastic on a recent ride in the mountains.

    - The sound is consistent no matter what the fuel level is.

    - The filter is brand new (came with the kit).

    I know some aftermarket pumps are louder than others. If it's the way this product sounds or if thereís a breaking-in period, Iíll live with it. If it sounds abnormal like a component is straining, Iíd like to know before Iím stranded. Please let me know what you think.

    Thank you!

    Did they replace the rubber mount for the pump? The noise you describe sounds like metal-to-metal vibration.
