Just relocated fuel tank from in the cab to between the frame rails at the spare tire location. I had the truck running after primed for a couple minutes and then nothing from that point on. I think I need a electric fuel pump to assist stock fuel pump. Do you think a 4-7 PSI pump would work best, would I need to regulate it if so?
You shouldn't need two fuel pumps. Make sure your connections are tight. Try to reprime the carb. I would use a cup with gas in it. While trying to fire up the motor have someone pour small amounts of fuel down the carb until the motor runs totally on it's own. If you decide to go the electric route then totally remove the mechanical pump and block off the motor with a plate. And yes 4-7 PSI is what you want. I'm not sure on that size pump if you need to regulate it or not.
Like the man said, you should not need an additional electric fuel pump. 4-7 is correct for a carburated engine and a pressure regulator should not be required, but it's a nice to have. Another nice to have is a spin-off canister style in-line fuel filter. If you use them, mount them as close to the tank as possible with the filter first, then the pump then the regulator. dv
I have tried primeing with a cup for over an hour and it just wont take. Don't know why but it just wont. I wasn't sure wether or not to block off the existing fuel pump with a plate but it seems as though that might be a good idea. And yes they are mounted in the frame rail as close as possible to the new fuel tank. And by the way there is one brand new high pressure fuel line running from the tank to the existing pump. And it has good clamps on it not the plier type. Don't believe I have any leaks. Thanks for your comments.
float in carb stuck maybe? if there is a filter in the carb maybe its pluged? are you shure your gettin gas to the carb from fuel pump? inline fuel filter plugged (just because its new dont count it out) have seen it before. new tank hada little junk in it and the filter plugged from it.
Well now. All I can think of now is make sure you have power and a good ground. Some pumps are pretty quiet and might be hard to hear over the starter. Have someone put their hand on it to feel if it's pumping.
Manual carb.... New in line fuel filter... took it off and blew through it.. all good, I'm going to just go with the electric fuel pump tired of it whipping my butt! Thanks for all the tips and advice. Hopefully she will fire tomorrow.
Oh yeah.... electric fuel pump and 15 seconds later purrin like a kitten. Thanks for the help!!!!! Roger
