    Need Help With Fuel Pump Noise

    Still have this issue. 3 warrantied Delphi pumps,all make the same screeching noise. Hard to believe 3 pumps would all be bad. Checked the fuel pressure,right at 50psi. Replaced the fuel pressure regulator,no difference. Car runs fine,pump just horribly noisy. Any other suggestions? Thanks

    Need Help With Fuel Pump Noise

    Thanks,is Delphi a oem pump? That's what I'm using,and was recommended. Pump makes a high pitched whinning,squealing noise. Almost sounds like a vacuum leak,but it is definitely the pump.
