FUEL PUMP HUMMING NOISE
all,
i have recently discovered a humming noise when i start the car and it has been determined that it is the fuel pump.
anyone know a good source for a new one??...thought maybe someone had a spare they want to sell.

Hey, how long since your filter was changed? I had a bad fuel distributor head on an old CIS porsche (it made the pump work really hard like a dirty filter would) and it made some noise.

i've read most of the "humming" noise posts and my gas tank is and always is kept full...
i was told there is a rubber grommet which keeps the pump from vibrating against other parts and this can sometimes move or fall out of position??
either way i thought it would be a good idea to replace the fuel pump this winter and i can look around when i pull stuff apart to investigate the rubber grommet.
again anyone who has a new spare fuel pump they want to sell let me know

hello William, the fuel pump is totally enclosed in a rubber housing, so vibration against other parts is
out of the question.
10 years is a good life span for a fuel pump, so a new one is not out of the question.
Source it from bosch, part no; 0 580 464 058, for a simple reason.
From bosch, the pump comes with the fuel actuator valve, whilst from porsche, the valve is an extra (40 euros in europe)
A new fuel filter is an obligation with a new pump, you do not need to change the gas tank filter
out of the question.

What is a fuel actuator valve?
Is this what we call a check valve, intended to maintain system pressure for a short time after engine shutoff?
thanks
