1982 CJ7 fuel pump hums / vibrates
Hello all, There was a post on this from 2011, but didn't see a solution, so I am starting again. Here's the scoop. A couple times after starting the engine, i take off and when shifting into 2nd gear (and 3rd) and accelerating, it would start to lose power, like it couldn't handle the extra gas or air and it would sputter. I didn't give it much thought because after turning the ignition off and back on, the problem went away. Today, it did it again. As I was sitting at a stop light heading back home, I heard a weird hum/vibration sound... kinda like a high-pitched air compressor. Anyways, I got home and left the engine running... I got out and walked to the back... I could feel the fuel pump vibrating. Now, this jeep has an aftermarket 20 gallon fuel cell and the Mopar MPI conversion. I can go down there and replace the fuel pump and filter, but wondered if anyone else has had this issue and how it was solved?
