Re: Fuel Pump Vapor Lock
No return line (part of problem) Has single line to pump.
Ok, got engine to normal heat 170, when we see the filter start to emty out, shut off, then with the line pulled off before the fuel filter , start up, the pump intermittantly spits a bit of gas , nothing like it is supposed to, then we reconected it and cooled it off with ice, start engine, refilled float bowls, shut off disconnect line, cool with ice, and start up, it pumps pretty good.
I have never seen this. I have however in the past few years been geting parts from the local parts places that have been failing and not very good quality made in a different country, and having a hard time finding gas without alcohol. This is why i suspect a issue with the pumps or the alcohol.
