Shakedown trip to Carolina 2 weeks ago brought out some fuel issues. First was a no start condition after I arrived there and after I started it several times on Friday and Saturday morning. One of the local farmer-boys said "Crank'er up, let me hear it run." It wouldn't start for nothing. Messed with it till dark, slammed the hood and went in to watch NCAA basketball. Next morning I managed to get my head in far enough to blow through the gas line back to the tank. Bingo... started and I drove 125 miles back home with no issues. Monday I took the new sending unit out of the new gas tank, removed the collapsamatic sock screen and replaced it with the reinforced stainless screen out of the old unit. End of that problem. #2 problem... fuel volatization when hot. Seemed like each time I drove 6 miles to the local gas/mini mart and spent 10 minutes, it would not start. Drive home, check for start every few minutes with no issues. Found out by cracking the carb gas line at the mini mart that it was under pressure.
Well, here is the fix I'm going to try... In the pic is a .050 carb jet, soldered to a 3 way fitting. I will hard line this into the fuel line from the fuel pump to the carb. Another line from the jet to the fuel line from the tank will give the unwanted pressure an escape from flooding the carb. There shouldn't be enough fuel flow bypassing the pump from a .050 jet to affect flow to the pump, but will providing bypass relief from volatile fuel pressure due to crummy ethanol fuel. Can't imagine how bad it will be when the temps get into the upper 90's. Thoughts? Jethro.
