Hi, had a problem with what we thought was fuel pump failure so removed old pump and replaced with new. Once installed we discovered the problem was not pump failure but an earthing problem. My problem is now the new pump is quiet when idle but the faster you drive the louder the noise, it is a humming noise. Thought maybe new pump was faulty so took out and re-installed old original pump and now that is doing the same thing. Quiet when idle and increasing noise the faster you drive. Noise was never a problem before replacement, pump was only replaced as we thought it had failed. I have removed the pump again, there is no blockage on the sock filter to base of pump and no obvious obstructions. Can anybody please suggest what the issue may be? Any help would be appreciated. Thanks
have the same problem?
