I'm sure it's been discussed in the past, but my search came up empty. This weekend when trying to switch to my rear fuel tank, my engine would die. Switch it back to the front tank and it would fire right back up. After flicking the switch a dozen times, it would finally kick in the rear pump and all would be fine. So I'm assuming that my rear pump is going out.
My question is this... How much of a pain is it to change out the pump. I thought I remember somebody once saying that it's easier to lift the box off the truck and access the tank that way, rather then dropping the tank out. Is this true? What else should I look forward to? Any tricks I should be aware of?
'96...to answer the question, there's those who pull the bed, and those who don't. I did my front and rear pumps a couple of months ago. The rear I spread out over 3 evenings since I couldn't stand any down time. I did not pull the bed. e-mail me off-list and I'll be happy to share the gory details.
2 other things...first, I'd take a good look at the wiring from the selector switch back to the pump; unfortuneately, to check the pump connector you'll have to pull the tank anyway. Second, DO NOT go cheap and get a non-Ferd replacement pump. I did a lot of digging and found a good discount Ford dealer on the web. I spend 125 $$ each for front and rear pumps and did not pay sales tax. This was a little over 50 $$ saving compared to the cheapest local dealer.
Changing the pump isn't a hard job, the trick is gaining access. I've done it both ways...pulled the back tank to get to this pump (won't ever do that again) and pulling the bed to get to the front pump (much, much easier). I went to a local garage and had them loosen all nuts on the six bed bolts. Then I pulled the nuts and bolts at home in the driveway, pulled the tailgate off, loosened the fuel filler hose clamps, unplugged the tail and license plate lights and got a neighbor to help me. We lifted the bed up and back until I had room to do the front pump/tank. For the back tank you'd just lift the bed (ain't that heavy) off and do the job and then put everything back on in reverse order. This sounds a lot more complicated than dropping the tank, but it's not. Ditto on getting a good aftermarket pump...look for a part with a good warranty. Good luck.
