My 1993 Jeep Wrangler YJ with the 4.0 6 cylinder and 92,000 actual miles is having fuel pump issues. A year after i bought the YJ, I decided to replace the fuel pump becasue it was making noise (original pump) and the sending unit was bad. I had the fuel assembly replaced in March of 2022, 3 months and 1,000 miles later, it stopped working and was replaced under waranty. Seven months later, this pump quit and was again replaced under warranty. I asked the mechanics if there were issues with dirt/contamination in the fuel tank or wiring issues. They said none, won't tell me what type of pump was used or show me the pump. The only reason I returned to their shop was because they warrantied the pump. Anyone have thoughts on what is going on or have similar situations? The mechanic advised a "bad lot of pumps" and new pumps aren't meant to run on ethanol gas. Help!
