Thanks PapaBear. I have been tempted to buy rubber hose to bypass sections for diagnosing purposes but I guess i feared the hose collapsing would give me a similar issue and i would still be missing the actual problem. I may give it a try anyway just to see if it makes a difference.

you can add a clear filter to the line running to the fuel pump & watch it when it dies to see if it still has fuel in it, if it does then the issue would be from the pump to the carb

I have thoughy about that. The one thing that has stopped me from doing this is that it is a steel line and i didnt want to cut a steel line if i could get away with it. There is the short rubber hose from the main supply line to the pump so i may insert a clear filter in that location. That will at least let me know if fuel is reaching the pump at all times.
Thanks for the suggestion.

I've got two filters in the trucks. One just ahead of the dual-tank selector, behind the electric fuel pump, and another up front, where the metal line ends and where the hose turns up the side of the engine.

The rear one catches any crap coming out of the tanks and protects the electric pump. The front one catches anything from the long run, but is primarily to visually verify that fuel is getting up front

I usually run two as well. I had one in between the two metal fuel lines where the cab and bed meet and have always had one between the pump and carb(close to the carb). When i installed the electric pump it has a screw in filter for the pump and i eliminated the filter between the two steel lines. I can use a small metal filter in between the two lines because i cant seem to find a small clear filter that fits in the short space.

How are your fuel lines routed from the main line to the engine? My steel line from the manual pump snakes behind the power steering pump and other accessories over the intake to the carb. Its what was on the engine and i have been running it for 3 years before this problem developed.

There is a filter on the end of the pick-up tube on the sending unit. Could be plugged.

It wasnt plugged as of last night when i dropped the tank. The old one was in decent shape just showed surface rust on the outside of the pickup tube as well as a little gunk inside. I replace the sending unit thinking it may have been restricting the flow.


One thing i just noticed is that after sitting overnight the fuel filter and fuel bowls on the carb are full again. I ran it for about 35 minutes last night before it ran out of fuel. No amount of starting etc woukd get fuel back to the filter but after sitting the system is full again. This thing is driving me bonkers.

Lower fuel filter between tank and pump.

These are a few shots of my fuel filters and their fuel levels while running.

Have you checked your pickup tube in the tank? On my 64 the pickup tube looked fine and I could blow air through it but it was restricted will some rust. My 350 would go 2 miles and run out. I did all the things you did and it didn't make a difference. It would die on me and the carb and filter were dry. I would let it sit and the next morning my filter was full of fuel and it would start up. I finally ran a rifle barrel brush down the pickup tube in the fuel tank and it cleaned out some deposits and rust. Runs great now.

Could try running it out of a jerry can right behind the electric pump. That would at least tell you if the issue is at the engine or at the tank.
