Subject: RE: Buzzing Fuel Pump
By the way, mine failed on my wife's Audi.
It failed after only 60,000 mi, so I checked into a possible cause.
It turned out that a fuel line was kinked between the pump and the engine, as installed by
the factory. This caused excessive back pressure and premature pump failure.
You might want to check into this if your pump fails with relatively low mileage.
