If I don't see fuel, I go after the gas line. This is the only thing you
haven't moneyed with. I have an old truck, and I just piped around it with
copper tubing from NAPA. ...bill in oregon

Subject: [Spridgets] fuel delivery issue
Hi all you wealth of knowledge:
My Bugeye with a 1275 has been giving me a challenge lately. Last year it
would die suddenly after driving for a while, and usually after sitting at
idle for a while and then pushing it hard. I would sit for 5 minutes and
then it would start and run normally again. It seems like it started after
I dropped the fuel tank to reseal the sender unit. I had been having gas
leak around the sender if I filled the tank full. I thought I had a non
vented gas cap, so I bought a new one. Still happening even if I leave the
cap off or loose. I have an aftermarket Mr. Gasket electronic fuel pump
mounted just above the fuel tank in the axle tunnel. I thought it might be
acting up, so I put in another one I had and got the same result. I have a
glass fuel filter in the engine bay, and I can see that when I first start
and until it gets hot the filter is full of gas. When it starts acting up,
I can see that the filter is empty. I thought about vapor lock from heat in
the engine bay, so I insulated the fuel line from where it comes up from
under the car to nearly the carburetors, leaving the filter uncovered so I
can see. It is still happening. Does anyone have any idea what is going
on, and what I can do to stop it? I used to have the fuel pump in the
engine bay instead of near the tank. I thought having the fuel line
pressurized from the tank forward would decrease the likelihood of vapor
lock. I don't remember having trouble with vapor lock when the pump was in
the engine bay.
Thanks for any help.
