Fuel Problem (I think)

First of all I know there is a fuel leak because if I fill the tank completely full I can see it leaking when I slow down and even after I stop I can see it drip from the end of the gas input tube that goes to the tank.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

<o></o>

But also I will be driving along and it just dies randomly, I can not see a common denominator at all? I did notice that the fuel filter, that is clear and up by the carb is empty of gas when this happens. Usually I can start it right after it dies, but every once and a while I have to put a little gas in the tank and it starts up. I'm sure it is not out of gas because I put in a very little bit of gas and then drive at least 10 miles.<o></o>

Try a couple bottles of iso heet and a couple of Heet since water has a high surface
tension it can gather together at openings and block the flow of fuel and after it has
sat a bit or you make the fuel move around(by dumping in fuel) it dislodges the water
and you can get fuel flowing again until it builds up and blocks again. If you have alot
of water building up in the empty space on the top of the tank it can rust a hole right
through the tank and you should replace the fuel tank. A bottle of heet every other
oil change is cheap insurance and will help prevent this in the future!!

For those of us that couldn't possibly read that small text.

Take an air hose and blow air in the fuel line back towards the tank for a few seconds and listen for bubbles in the tank

The sock on the pickup tube may be plugging up.

If that fuel leak is in the fuel line, when you'r driving along it may allow the fuel pump to suck some air into the line and eventually your fuel supply to the carb becomes mostly air, your fuel filter is full of air, and the carb runs out of gas. Stop for a while and some fuel runs into the fuel line, starts to leak on the ground, and now you have enough fuel in the fuel line to start it up again.

Can't guarantee this is your problem, but that might be the common denominator. (Of course, doesn't have to be a common denominator - you might have two separate problems.)

At the price of fuel, I'd get that leak repaired and then see if it still stalls when you are driving along.

may also be the gas cap vent is glogged... this will cause a vaccume inside the tank, not allowing fuel to flow... Try this, (you already sort of do it by putting a little gas in it...) after is dies, take the cap off and listen... does it suck in air? put the cap back on and see if it starts again... drive it until it quits again... this time take the cap off and leave it off or leave it loose... drive it and see if it dies... if it does not, you found the problem...

Update:

Last night I had the fortune of getting it up on a rack. It looks like the air intake that goes to where you put gas in has a rubber hose and it is very frayed and leaking. I patched it up as well as I could last night, have another car I can drive but was being used by my sister. As soon as I get the other car back from sister I am going to take the tank off and put on new hoses that come from the gas/air input to the tank.

Also the rubber fuel line that hooks up to the fuel pump was very frayed and leaking badly, I cut that one off and put it back on. Do you think it could have been pulling air in there that would cause the truck to just die?

BTW this is a great forum and I am fortunate to have found it.

The less rubber the better.

Steel tubing keeps gasoline cool, Rubber absorbs heat never mind it eventually breaks down and leaks air.

They come off pretty easy with the right equipment or enough guys.

Usually it is easier to lift up the bed set it on stands and drive out from under it.

8 bolts that you will have to replace and the fuel filler hose.

Look for any wiring that may have been attached
