Can anybody tell me about a check valve in the gas tank & if it could get stuck and not allow fuel from the tank. Would there be a way of resolving the problem?

Don’t think there is any in the gas tank, the mechanical fuel pump could have them.

Don't recall ever hearing on one before pumps were buried in the tank..intermittemt fuel starvation, good fuel pump?? maybe something in tank being sucked over line to pump???

Need  desc of actual problem to make intelligent guesses....

No check valve in the tank. There is a pancake looking permanent oilite fuel filter in the tank... not 

serviceable. It can plug up...easy enough to check that.

Also there is a special 1/2" long brass bushing that goes into the tank fuel line fitting before the steel line is screwed to the fuel tank. It seals the external line to the internal fuel tank line. With out it you will have a partial suction leak and the pump cannot suck fuel out of the tank to capacity...IE fuel starvation.

Thanks Bud,

 

I could not have had a better explanation of the gas tank connections.  Now that I have exhausted all other options of the fuel system it becomes obvious that the pump will have to come out.

 

Many thanks
