Something that old to have sat that long may have accumulated rust in the fuel tank. Now, it's breaking loose and plugging everything up.

should also have mentioned when you turn on the electric fuel pump let it run for a minuet, shut it off and check your fuel lines, if you see a wet spot in the line you found the spot where the problem is.

Change all the rubber lines, and if there is any doubt about the steel lines, put new ones on, too. That will cost you about $30 if you do it yourself, which is very easy on the old truck. Make sure the tank is clean. I would pull the tank and have it professionally steamed and checked. Make sure the pick up/sending unit is clean and unobstructed. If it restarts after between 15 and 20 minutes, though, there is one thing that is the cause of this in old Fords. The ignition control module is notorious for this problem. You have to 2 connector version, and it runs about $100 for a new one. Don't waste you time on a used one. They are readily available at any auto parts store, and they are normally in stock.

I have changed all the electrical components including the module just because they were old. The ones I put in were all new top quality ( I get a big discount at NAPA ) I changes all the rubber hoses and checked the lines for leaks and obstructions. One thing I noticed is when I blow air through the system neither tank bubbles just air coming back through the filler neck. I put 10 gallons in each tank so I am totally stumped.

well you could try taking the nozzel on the blower and wrapping it arround a rag, then stuffing the rag into gas tank neck making shure no air escapes from the neck when you apply pressure. hold pressure for about 1 minute. should show where problem is by wet spot in line.[gas leak]. hope this helps
