Hi, I am 17 and just got a 1966 chrylser new port and started working on it. We can't seem to get fuel to the motor. we replaced fuel pump and checked the fuel lines and they were good but when we blew air into the gas tank we couldn't get it to come out either side. any suggestions on fixing this or does anyone know how the gas line goes in the gas tank? I don't want to replace the entire gas tank so if there is any suggestions I would appreciate it. thanks

 

If it is a big block, check the fuel pump pushrod. It is a wear item.

 

when we changed the fuel pump we checked the pushrod and it was fine I believe

 

If you drop tank and remove the fuel sender/pickup you'll find a filter "sock" that probably deteriorated and plugging fuel line tube.

 

alright thank you I will do try that next

 

If the car has been sitting for some time, dropping the tank and giving it a good clean out along with replacing all the hoses and the filter would be a good idea.

 

If the engine has not been started or this just happened I would take a gas can and hose to the fuel pump and start it. If it runs then you have your answer and dropping the tank is warranted.

Being an old car, inspecting, repairing and possibly upgrading the whole fuel system is always a good idea. If it's not failing now it will.

 

This sure sounds like a tank / pickup or supply line problem

And no, LOL, I don't work there.

If you read through the fuel section, there are checks you can make on the pump to determine if it's OK, EG, buy a vacuum / pressure gauge at the parts store, which don't cost that much. The pump should be able (generally) to pull at least 10-12" vacuum Hg.

Not being able to blow air back into the tank sound like that is the trouble area.
