How does it idle?
Have they been into the carb? Especially the floats, the pivot for them. Correct adjustment?
Have you really searched hard for vacuum leaks?
By chance, have you "plugged off" your bowl vents on the carb (can no longer breathe)
Does your truck have a fuel return line going back to the tank. Or used to?
Any mods other than OEM to engine/ fuel system? Like, it was a mechanical pump and is now electric?
What is fuel pressure?
How fast will the fuel pump fill a measured pint vessel. In seconds. Maybe the "Sock" in the tank is stopped up.
Some things can be Redneck tested, such as connect a fuel can to the rear of a MECHANICAL fuel pump (not using the truck's tank) See how it does not sucking thru the "sock", but from the "Remote Tank"---Use extreme caution if you do this, a fire extinguisher is HIGHLY RECOMMENDED CLOSE BY
May have some more, dependent on some of your answers
