Read a lot of good post here on fuel pump issues, but none have addressed my question completely. I recently purchased a 1990 w/2.5 4 cyl. Jeep had been setting for several years. Driving it home, the fuel filter keep clogging up. Removed the fuel filter and found large pieces of what appeared like rust. Installed new filter, but problem recurred after 20 min of driving. Changed the filter three times to get in home (trip was 250 miles) After I got it home, I found if I let the car set for several min, it would run fine for about 10 miles, then loss of power again. I took the gas tank out, and found pieces of rubber in the tank. Both the rubber line on the fuel pump and the rubber seal at the bottom of the return line were deteriorated
Two questions: Did something in the fuel cause the rubber to deteriorate, and how is it possible for a debris in the fuel tank to get past the screen on the pump itself.? I guess the reason the car would run again after setting is that the loss of vacuum at the pump would cause the junk to settle back down to the bottom from the fuel pump screen. My original problem might not have been the fuel filter to begin with. Any thoughts.
