older cars. If you have non ethanol fuel available in your area it is worth a

Subject: [FWDLK] 1957 Dodge Fuel Supply Problem -- Any Help With This
My mechanic and I are having trouble diagnosing this problem
with my 1957 Dodge Custom Royal with the 325 wedge V8 engine:
After running for a while on warm days, the car starts acting
like it’s starved for fuel and often stalls out. This happens only when
driving up a road incline of more than a couple of degrees. Normally I’ve
been able to restart it right away, but yesterday, every time I restarted the
engine, it would run for a couple of seconds and shut down again.
I’ve reported this issue to my mechanic since it started
about a year ago, but he’s been unable to find anything wrong. Yesterday I
had to have the car towed, but when it arrived at my mechanic’s place, he
started it right up and drove it into the garage and it ran fine. Again,
he can find nothing wrong – no clogged lines, and the fuel pump is pushing out
plenty of fuel.
Again, I’ve observed the problem only on hot days (yesterday
was 81 degrees), only after driving for at least half an hour or so, and only
while driving up an incline. I’ve owned the car for 20 years and this is
issue appeared only in the last year or so.
Anyone seen this themselves, or know what the trouble
Thanks for your help!
