AGAIN the same problem happens when the cap is on or off the truck!!!!
When there is a 1.5" hole in the top of the gas tank, how can it be pulling a vacuum?!?!?!?!?!

he is right, from the pump to the tank, the pump will pull a vacuum on the tank, this is how it sucks fuel from the tank to be used in the carb....when i was talking about long lengths of rubber line, i actually meant between the pump and the tank. This is where the line will suck shut and stall the engine...from the pump to the carb the pump is producing pressure, rubber lines not that big of an issue on the pressure side, except for possible leaks and fire hazards! I would limit lengths of rubber lines in the fuel system to 2-3 inches, just to make connections between lengths of hard line or filters.
