Electric fuel pumps

So I'm working my 59 f100 with a 302 that I just installed. I bought a new carter electric fuel pump and put all new lines from the pump forward. The only old line I reused was the line consign out of the tank 18inchs or so. Which I blew it out before reinstalling it. The tank is not new but good no rust ect. I went to go fire it up last night for the first time and I can't get fuel to the pump. I can hear it run but nothing. Just a couple drips in the fuel filter that is right before the pump. I never used electric pumps before so don't know much about them. I thought it would be strait forward but it's not so strait I guess! If anyone had some tips or ideas I would like to hear! Thanks

 

Sounds like you have a plugged line or it's ****ing air somewhere. The pump should have an in & out marking on it. Check that. Other possiblilty is when you blew the line out to the tank (***uming you used compressed air) maybe the pickup in the tank got damaged. Disconnect the line from the tank at the pump and see if you can get gas to flow. Let us know what you find

 

a lot of electric fuel pumps do not pull fuel from the tank like a mechanical pump does. make sure the pump is lower than the tank and is oriented in correct direction. also make sure the tank is properly vented.

 

I had a Chevy woody wagon that would run out of gas at 1/2 tank. I finally pulled the sending unit to find the dip tube had a vibration crack half way down. If your line has a crack or a leak anywhere it will **** air and not the fuel.

 

Ok there are some good ideas and thoughts! Thanks guys I'm going to mess around some more after work.

 

there's gas IN the tank -- right?

 

You can check the line by putting the compressed air line into the fuel tank filler, sealing it up with a rag, and put the fuel line (the inlet to the fuel pump) into a container. Electric pumps will **** uphill, but they have to be primed (run) for a while before the flow starts (they are very efficient pumping liquid, but lousy at pumping air.)

 

I once had an electric pump spinning backwards because the wires were switched (after a fire - long story). Wouldn't hurt to check.

 

One of my cars I had to blow air in the filler to get the pump primed. It was good to go after that. Unless you ran out of gas.

So I think I found the problem. The tank have to be around half full for the fuel pump to work. So I would have to say that the pick up tube is cracked. So this weekend project is to figure out how to replace the tube without replacing the tank

 

I forgot to thank all the input. Thanks for the help
