I just put a new rebuilt ATK motor in my Jeep. The fuel pump needed replaced so we bought a new Jeep filter and brand new Jeep fuel pump. Its has loud whining noise. We just took it back and have another new one on order. Any one with any advice would be helpful. We checked lines and anything else that could be a problem.
I replaced the fuel pump on my jeep for a non jeep part, but this one is a lot louder then the original pump. At idle, you can hear the pump noise over the engine noise. Its working like this for a year now, but it still irritates me a bit.

Update: Put second new Jeep fuel pump in after a couple minutes it starts whining again just like before. So we take out the new Jeep fuel filter/regulator and replace that with a new Purlator filter/regulator from Advance . Now it's totally quiet. So it was not the new pump it was the new regulator. Crazy to think that a factory new Jeep part failed and a new Advance part was better.
Try it next time and the Advance part will be bad and the Jeep part will be good. You can't tell with this stuff anymore and it's getting worse. Its all disposable junk built with cheap overseas labor.
