Fuel pump question

53 Pontiac, L8 motor, fresh rebuild. Gas lines are clear. Fuel pump rebuilt prior to rebuild but has been sitting in a box for over a year. Manually cycling the pump produces "some" suction. (Another person was feeling the suction while I pumped). Pump was rebuilt with current materials for current gasoline.

Installed/removed/installed pump 10 times to insure it was put in correctly and under the cam lobe. Cam lobe is there.

However, pump will not pump gas from lines at all. A stupid question would be does it need to be primed? It is one with the gl*** bowl that always full during the normal process.

Anything else to look for? Or just bite the bullet and order a new pump?

 

is the stock tank still in there? remove the line at the tank .ck the pick up at tank if its orignal alot of these pickups in the tank dont have a screen, make sure you have not ****ed something in the line at pickup that has you plugged

 

Sometimes they do. I prime mine by mounting it up, hook up the tube from the tank, and then pump air into the tank at about 5 psi, til gas flows from the outlet of the pump. Hook up the tube to the carb, pour a couple teas****s of gas in the carb, and crank it up. If that doesn't work, it's the pump or the pickup tube in the tank. Or the tank is empty.

Just be careful pressurizing a gas tank. Compressing gasoline vapor sounds like what happens in the engine right before the big bang...I've used gravity in the past successfully.

 

It needed to be primed...new one for me. Used a vacuum pump on the line at the carb intake. when it got gas, hooked up line and she's pumping fine. About to start, then NO FIRE. If it's not one thing, it's another.

 

Sounds like you have my luck. Cant be much though if its points dizzy. Let us know how it goes.

 

On I6 chevys the fuel pump will bolt on upside down but will not work. It looks like the arm is on the lobe but it wonk work. Just a thought.
