I believe you. Instead of installing the old tank I'm going to go get 5 feet of rubber fuel line. Attach it to the fuel pump and run the other end of the hose in a 5 gallon gas can rt in front of me. Beg the fiancee to turn the engine over so I can observe if its pumping at a reasonable rate and see how much is entering the carb.

I had originally asked about the fuel filter being drained and slowly filling back up over a minute or so while  not cranking the engine.

Once the fuel system is primed the filter should never be dry of fuel correct?

correct, that is why they have a check Valve between the gas tank and the fuel filter If I remember correctly. but one should be there.

OK Ill get the hose tomorrow to narrow down some of the variables. I'll be sure to comment back with what i find and any additional questions.

Thanks again

You may have an air leak some where between the tank and the pump, which would give an air lock.
