now were on the same page lol.
so its obvious we have either a pump lever problem, Where its not physically operating the pump, or its a siphon issue.
Ill pop a couple of possible things and lets see if any click.
i doubt its a camshaft problem, or it wouldnt have ran before. Im going to ask kind of a silly question, but are we sure that the pushrod was put back in, an not lying on the floor, lol.
Ive seen this tons of times before believe it or not.
If its a syphon problem, the fuel is running back to the tank from either a missing valve on the new pump maybe?.
or im thinking that we need to prime the actual fuel line itselt.
The line from the pump to carb should have a internal valve and should not let it run back to the tank,so it shouldnt be that.
Im just really beginning to lean towards a lost prime, and the pump is not strong enough to pull fuel from the tank for some reason.
I have a 59 buick this past summer, put on a fuel pump and the system lost its prime. no matter how long i cranked it or added fuel to the carb, i could not get it to run.
THe only way i got the system primed was i had someone add shop air to the fuel tank with a air blower (be carefull not to blow too mutch pressure in the tank, lol) with the line off to the inlet of the fuel pump, when fuel shot out, i plugged it with my finger while i attached it to the pump, I than took the line off just before the carberator and applied very minor pressure to the tank (again being carefull not to blow the fuel pump diaphram this time) and cranked over the engine with a pressurized tank. than i finally got fuel prime.
attached to the carb and away i went.
So as long as its installed properly with all of the parts, than i think we just have a prime problem. and we just have to give the fuel a little help to the pump to get things goin, once its primed it should hold its own prime.
lets give this a shot and let me know
