New guy here, 63 Valiant Convertible. I have the CA pumps but I can get gas to pump with it upside down but it only takes a little fuel and then dumps out all over the place. today i ran out of gas with my experienced mechanic with me in the car and then went to the station and it took 4 gallons before dumping out. I let it sit and then tried again with the same result. Any thoughts? Could a vent line be plugged or something preventing more gas from going in?
