[QUOTE="BenBB, post: 1299935, member: 20185"] Awesome, I was thinking about this thread and hoped you'd post an update. The more I thought about it, the less probable the pump itself seemed (sure it COULD have failed exactly when fuse 27 finally gave up, but more likely not), and even a burnt wire in the harness would likely result in unrelated symptoms (if the wire got hot enough to melt it could cause short circuits in, say, taillight wires or whatever else is in that harness). I had to google FPDM and found this thread in another forum: [URL]https://www.f150forum.com/f4/fuel-pump-driver-module-check-yours-152908/[/URL] Looks like a common, or at least potential, failure point. Considering that, I would guess that in your case the sand in the connector contributed to the fuse 27 failure, as it wasn't making a good connection and drew too many amps...just a wild-ass guess though. Anyway good info and here's hoping you solved the problem and you don't wind up unraveling a wire harness looking for a burnt wire or dropping the fuel tank for a new pump. [/QUOTE]
