I am new to older trucks, and thought it would be fun to fix up an older F100. I always liked the looks of them and the way they sounded. I bought a 66 custom cab with a 352 in it. It drove really nice and I bought it from the old man who bought it new. After paying the man and signing it over to me it would not start. He told me he would clean the carb and I took delivery from it the next day. The next day it was running when I got there and he told me to put gas in it as soon as possible because it was almost out, but on the way to gas station it died on me. I walked to gas station and put 1 gallon in it and it still didn't start. I called the previous owner, and he said he thought this was an as is deal. But he still helped me out by putting gas in the carb, and after filling up at the gas station went home about 35 miles away. I made it home fine.Later that night I tried firing it up, and it did not start. I can get it to fire up a second with starting fluid or a little gas, but it will not keep running. I bought an inline fuel filter, but cannot find old one to replace it. I disconnected the fuel line from carb and put it in a bucket and cranked the key, and no gas came out. But how did I drive it so far days before if the pump is out? I changed diaphragm in the accelerator pump, but now no gas is going in carb. Does anyone know what the problem might be. I put injection cleaner in full tank, because the previous owner told me it sat for several months. Any advise would be appreciated - Thank You Twister

 

The original corrugated paper cartridge fuel filter fits inside a canister that threads onto the pump.

Some people are unaware, so they install an in-line fuel filter. Meanwhile...the original fuel filter is getting more clogged up every day.

Like Bill I think you have a fuel delivery issue, minor even though agravating for a new purchase.

Welcome to FTE

The good news here, the problems are fairly easy to diagnose and remedy. The bad news, you probably have all of them. It's strongly suggested you obtain a Shop Manual for your truck.

It can be kind of overwhelming if you try to focus on everything that will be wrong with your truck. Decide what your plans are, and a budget.

The manual is broken down into sections, that's what you'll want to do as well. The fuel system is made up of the tank, sender/gauge, filler tube, cap, fuel lines, fuel pump and carburetor. All of it will have to be inspected, cleaned or replaced, adjusted, repaired etc. Start by replacing any rubber hose, there is one under the cab that is often missed.

Inspect the inside of the tank for sludge and sediment. It may need to be removed for cleaning or replacement. There is no way around that. Blow out the hard lines with compressed air. Replace fuel pump, get a kit for your carb, and rebuild it. Not trying to be Debbie Downer here, spending time, and money on these trucks can be very rewarding if you go in with an understanding of what's involved. A methodical approach ultimately saves both.

 

Thinks man, I replaced the fuel pump and still no fuel. Is it clogged inbetween the tank and the pump, possibly? I have a second gas tank in the bed. I don't know if that was factory or not. I replaced the air cleaner because it was the oil type. Thanks for any help.

 

The tank can be clogged. You may have to remove it, clean it yourself or take it to a rad shop and have it serviced at a higher leval.

The only fuel tank these trucks came with was the in-cab tank. The auxiliary tank mounted in the bed is aftermarket.

The oil bath air cleaner was standard equipment in these trucks. It does a far better job filtering the air than an aftermarket paper filter type.

 

That's the thing, piecemeal repairs just won't work too well going this far back. Each system has certain operating parameters - they are pretty wide, but they must be in the ballpark. Fuel has to be a certain pressure and volume or it will never run right and you'll go crazy trying to figure it out. Blow out the lines with compressed air. There could be leaks in hose as well as obstruction in line. We don't want to draw a bunch of sludge and sediment into our nice new pump and rebuilt carburetor. Go slow, take your time and do a thorough job and you won't have any "callbacks".
