fuel pump
over the last 2 days ive installed the pump and new hoses. i drained all the old gas , and added about 3 gallons. The car will turn over with a spray of starting fluid but thats it. To day i tried to add gas from the feed line right to the pump itself, but not sure how much . im sure the pump is a batter pump then a primer.
I then just took about an oz of gas and dumped into the carb itself then it would turn over and run untill i would hit the gas then seem to just die.. not sure if this will hurt anything but its the only way it will run for a few seconds i would think it would suck gas down the line.
help !! haha Thanks Tony

I'm wondering if there is a problem with the pushrod engaging or the new pump itself? I think I saw a thread where in order to check the pump you should disconnect the line at the carb, put it in a bucket and crank the engine to see if there is any flow. (those with experience chime in here) Also, if the rod is put in wrong you could do some damage so it might be worth it to pull the pump and check the rod placement before running it anymore.

If the pump isn't getting gas, put an air hose nozzle in the gas tank filler with a rag around it and gentle squirt air in the tank to force it up to the pump, check lines under the car for wet spots that are leaks and are letting air in the system.
Otherwise the pump is bad.

I'm not sure, does the 78 pump still have the return line?
If it does, any chance they got mixed up (I know they are different sizes) when you connected the rubber hoses at the pump or tank?

Some people tighten a set bolt in the front of the block that can be used to pinch the push rod, to keep it from falling out when removing the pump. Did you do that? The pump sometimes needs to be primed in order to start functioning. It only pumps in convulsions, like an upside down jug with water in it. Run a rubber line from a gas can direct to carb, run the engine for a while, while catching pump fuel in another can. Then reattach lines once pumping is generous and consistant.
