64 Valiant Fuel Problems, PLEASE HELP
Use a piece of rubber hose and hook it to the inlet side of the fuel pump and run the other end into a gas can and try to fire the car. If it runs on the can you have eliminated the fuel pump and carb as the problem. Next, buy or borrow an electric fuel pump and hook the rubber hose to the hard line going to the tank, start the pump and see if it draws fuel. If not, hook your rubber hose to the other end of the fuel line and into the gas can and see if the pump draws fuel through just the hard line, if so, the hard line is unobstructed, and must be either the rubber hose going to the tank, or the gas cap vent, if the tank and sending unit are both new.
I just did this on this old Trail Duster that had been sitting for 3 years, turns out it was the rubber hose at the front of the hard line that went to the fuel pump, as Rusty mentioned.
