Vince, Cleaning the tank without sealing it is a never ending job. A 78 year old tank will have lost it's tern coating long ago, and the alcohol laced fuel we get today attracts moisture and induces rust. Everything that the fuel comes in contact with needs to be protected. You do have a restriction in your line, even if new. Blow it back to the tank and you'll be good till next time it clogs. The other possibility is your flex line. These are of rubber and collapse inside from the new fuel. There are new fuel resistant lines advertised in the V8 Times.

Thanks Alan--I did replace the fuel line and the guage line-I'm on my 2nd fuel pump-Cleaned out the tank before I re-installed it-Replaced the carburator-The only thing I didn't do was replace the sending unit-It looked like new --Now Im woundering if that unit would stop the flow of Fuel into the Pump--To drop the tank now, I would have to remove the spare-The spreader bar,Both Fork Horns -Both tailights etc etc-I really dont want to do this again unless that is the culprit--Could that rod that works off the cam shaft, that controls the diafram be worn??How can I check it.?How far should that rod be moving up and down??It is moving when I hit the starter--Hair is getting grayer by the day--What a mystery?? Thanks (anyone) for any advise- Vince

Vince, try blowing into the fuel line. you've likely got a hunk of debris that stops the flow. When it has cleared, try your pump again. It will happen again, so be prepared to replace your fuel line, and clean/seal your tank. As a side note, install a fuel filter before the pump.

Having a problem getting fuel from the tank, to the fuel pump-I tested the pump out of a can of gas,sat lower then the pump and the gas flowed out fine! I was pumping it by hand so I know the pump is good I tried priming the bowel and still nothing comes out of the tank ,,-I put 10 Gallons of fuel in the tank when I hook up the pump to the fuel lines that go to the tank I get no fuel--What is stopping the fuel flow from the tank to the fuel pump??I"ve tried everything but dropping the tank--Does the sending unit have anything to do with the flow of fuel to the pump??? I"m really out of ideas,Also the pump piston is working-when I hook it up and hit the starter,I can see it moving up and down--Any suggestions would be greatly appreciated--Thanks Vince
