1992 Ford F-250 Q&A
1992 Ford F-250 Question: Fuel pump problem
My fuel pumps I keep putting in my truck in the rear tank are going bad. I have tried motorcraft and airtex fuel pumps, but same problem. Any idea why these pumps are going bad? - Visitor
dirt and debris are the most common reasons for failure. remove the tank and have it completely cleaned out. Roy - mastertech6371
Are you sure the pumps are bad? If not you might try powering one up out of the truck. Some times fuel pump relays heat up and work intermittantly. - verdigo
Check your wiring harnesses also. They are known for issues, and even had a TSB for harness pigtail replacement on similar models. Look for damaged connectors and corroded terminals. - DaveJHM
