How long should it take to replace fuel pumps?
Does anyone know what the normal time is for a dealers shop to replace both fuel pumps on a two-tank F-150?
Is $1000 a little high to replace them and add the check valves?

Mega,
Don't know how long a shop should take. It took me 2.5 hours in my driveway to do the front FDM (fuel pump) on my '90 F150 SC. That recall doesn't do much to fix the problem and it's only warrantied for 12 mos/12,000 miles. Your problem is called cross-flow and its caused by a faulty check or shuttle valve on the FDM in the tank THAT OVERFLOWS. If your rear tank isn't also getting gas from the front tank, the rear tank FDM is probably good. I didn't know this and made the mistake of dropping the rear tank to replace the FDM there. This didn't solve my problem. Then found out that the FDM in the overflowing tank is the culprit. Since I still had the old FDM from the rear tank, I had a shop loosen my bed bolts. I went home, pulled the nuts to these bolts, removed the tailgate, loosened the gas filler hose clamps on both tanks, unhooked the tail and license plate lights and lifted/scooted the bed straight back to get access to the front tank and pump without dropping the tank. The FDMs cost about $150 to $225 each down here in Texas, depending on supplier. $1,000 sounds like a ripoff if you ask me. A reputable shop should be able to do both your FDMS (if both need changing) in about half a day for a lot less...that's my guess.
