Well, I last summer my fuel filter/ pump started squealing, and making vibrating noise, replaced the fuel filter changed the noise slightly, some times it would go away, sometimes the line going to the filter under the hood would vibrate, couple weeks ago truck warning light came on- "low fuel pressure warning" came on, hum... went out, came on a couple days later, then finally put me into limp mode, luckly only 1/2 mile from home... checked filter on frame/ tightness, it was tight, the pump on the filter housing was very noisey still, well, I priced the filter/pump at dealer $360.00, ebay $198.00, i figured 200 dollars cheaper than taking to ford....I waited and pump arrived 3 days later, replaced it and low pressure warning still on, but pump was very quiet, and when I restarted low pressure warning and reduced power came on in driveway, hum.... I thought code was still in computer, I disconnected battery and turned headlights on to try and kill the code, started it and now the engine light came on, nothing else, and truck ran fine....hum.... went to autozone, and they pulled the code, low fuel rail pressure, p0087, hum... guy said to drive and code should go off, truck runs fine. Drove truck a couple days and engine light went off, Truck runs great.......All is good, only $200.00 fix... hope this helps someone else....

 

When I read the title of the thread, I was thinking there would not be a $200 happy ending. Glad it worked out for you!!

 

Is the pump covered under 5/100,000 warranty?

Doesn't sound like it is.

 

My truck has 106 k on it.....so I didn't even try......cause once they tear into it and they say its not covered, then I stuck paying the big $$$$'s

 

If you use the Motorcraft fuel treat, you could have the little disk under the cap in your fuel tank. It has happen to me. The disk is just the right size to block the fuel pick up tube. The dealer dropped my tank three times before they found it.
