Re: Fuel Pump Noise

Many, many years ago my 88XJ was "rear-ended" and the insurance company replace my fuel tank and fuel pump. That pump developed a "hum". I did a search for a "fix" and found one that required removing the fuel pump and trimming a metal bracket/plate to eliminate the hum. I decided to replace the fuel pump when it failed and not before. That was about 400,000 miles ago. That fuel pump still works just fine and the hum appears to have disappeared. The check valve, in the fuel pump, then failed and I corrected that by adding an inexpensive external check valve.

Best regards,
