Hey all,
I'm new to the forum and I wish I knew about this site a long time ago.
I have a 96 F150 6 cyl 4x2, manual transmission, dual fuel tanks. I am the original owner of this truck and have had it for almost 13 years and 185,000 miles.
I love this truck but lately have been having a fuel issue like many others. My front fuel tank is not working correctly. When I start the truck on the front tank it sputters and then stalls. When I start it on the rear tank and then switch to the front tank it will sputter and then run, however, when I drive it, it seems to hesitate a little or just not have "it".
I'm confused, Does the front fuel pump quit all together or does it fail intermittantly? Does this sound like it could be something else?
If the fuel pump is bad, would It still be able to draw enough fuel to the engine?
I read up on several other threads and tried turning the ignition with the front pump on and I can hear it sputter. Rear tank is a normal sound.
Please Help,
ski
First, replace the fuel filter. If you've never done it, it's long overdue. You will need a special tool to remove the fuel lines from the filter.
If that doesn't fix the problem, then the fuel pump is failing. They fail exactly like that - the pressure gets lower and lower until the truck won't run on the tank at all.
Sounds like you are right on the money.
Is there only one fuel filter that both tanks flow into? If the filter was bad, wouldn't it affect both tanks flow?
I'm guessing it is the fuel pump. Now to find out what it's going to cost me to get one put in.
I should have been more specific. Changing the fuel filter if it's clogged, is only going to prolong the inevitable, which is changing the fuel pump.
It's not hard to do it yourself. When mine needed it, I took the bed off and changed both pumps for good measure. It took an afternoon and a buddy to help lift the bed off.
Modern Chilton and Haynes manuals are only good for outfitting the outhouse (smooth paper). For In-depth repair on your truck, they are totally useless. They only cover the "basics".
There is NO substitute for the OEM manuals. They're available on Ebay almost continuously in paper form. I notice that copies of the OEM Ford CDs have disappeared, Helm finally took notice I guess.
Ski1559, PM me and I can help you out. I have a set of manuals on CD.
The easiest way to change your fuel pump(s) is to pull the bed. That can be a PITA, but it is MUCH better than dropping the tank(s). Use lots of PB Blaster and heat where you can use it safely.
Not really. Six bolts and the bed's loose. Disconnect the wiring for the taillights, and disconnect the filler hoses. The bed just lifts right off. It wasn't even that heavy, it's just sheet metal.
