I've got a customer that has a 79 Ford F150 302. The truck keeps eating mechanical fuel pumps. He bought one over a year ago and has replaced it, I kid you not, seven or eight times under warranty. That warranty is running out, it's not costing him much out of pocket, so much as it's been a pain in his ass. I told him it was a bad fuel tank, with 30 years worth of crap in it.
Bought a new tank, still puked a pump. Got fed up and took it to a shop here, and he put new lines under it. This last pump didn't even hardly run once on the truck. I think I sold it to him two days ago, and they just came in and exchanged it.
New lines, new filter every time, new tank. The only thing that's left is the sender. I've noticed that the arm is worn on one side more than the other. Now I don't know the age of the cam, and wouldn't rule out the eccentric lobe being worn down, however, that wouldn't cause the fuel pump to keep destroying itself would it? Sometimes they last two months, other times they last all of a week. This one was two days.
He's a genuine nice guy, and I'm more concerned with helping him get this thing straightened out than making a sale. I tried to sell him on a universal fuel pump, but he said he's got more time than money, which is understandable.
So what does the GRM braintrust think?
