68 camaro stock 327. car starts fine when i prime carb, or if i remove the fuel line at tank and stick in a gas can it will start and run! when i connect the fuel line to the tank, i do not get any gas at the carb... tank obviously has gas, and it did work once before... is it the pick up line in the tank? is there a vacuum line somewhere on the tank? the r/s gas cap does not seem to fit right either, could this also be contributing to the problem? i put a glass fuel filter on, and it never fills with gas, should it? i can see the gas "pulsing" into the filter, could my fuel pump be weak? thanks in advance to you guys way more knowledgeable than me, so any help would be Greatly appreciated.
