You mean stock 4.3 TBI tank? Isn't that for the EFI engine? It pushes like 45psi and if you have a carbed engine you would have to use a good regulator to bring the fuel pressure WAY down. Are you sure you're not flooding the engine? Next time it happens, pull a spark plug and see if it's fuel soaked. Just saying from the info you've given, it's my guess.

It should only be pushing about 14-15psi, it's only tbi not tpi, lol. But ya you will need to be running a pressure regulator and it should be a return style.
what about the pump...is the screen on the pick up clean?..
if you remove the fuel line to the carb and turn on the pump will it keep a constant flow or does it slow down or stop?
