Replace or rebuild carburetor.

Carb has been rebuilt! Also when driving it acting like it runs outta fuel at higher rpm? Driving normal runs fine

Thought bout trying different carb to see if that's it. I have another I could put on to try. Also replaced fuel pump too

Fuel supply issue... check line to pump, again.. then filter restricted or pump weak.

Jus replaced new metal gas line from tank to fuel pump today. Do you think it could vent issue from tank? It's a fuel issue jus can't pin point it, it did fine until changed fuel tank?

Did you also replace the rubber gas lines from fuel pump assembly to the metal lines and other rubber gas lines.

Yes, all new lines from fuel tank to the fuel pump, new line from fuel pump to the carb

Take the gas cap off and run it and see if it still quits. It could be a vent issue.

I had same problem, It was the filter in the gas tank. It is a mesh material that goes on the tubing that goes to the carburetor after it get old it will fold over and cut the gas off under pressure but when you cut the engine off and the pressure is off it will go back to normal and engine will crank up and run.

I am talking about the filter inside the gas tank, most people don't realize a filter is inside the tank. To keep it from happening I took the filter off and didn't replace it. The tank has to come out of the truck to be able to get to it.

Ok, yea I replaced my tank with new one, but if it keep doing it after i check other things. I will check that, thanks for the input

Thought I would return to my post and let everybody know what my issue was with My truck! Never would thought to Check until friend of mine had same problem! The fuel pump rod was too short!!! Yea iwouldnt have believed it either but sbc is 5 .75 in long and the one that was in there bout 1/4 shorter I know hard to believe but that cured my problem
