<VV> Heat and Vapor Lock

[Frank DuVal]

Need clarification of what you are experiencing.

If you can start cold and drive a short OR long distance with no 
trouble, then stop for 10 minutes or so and a restart results in running 
for only a few minutes, that is vapor lock.

If, you can start cold and only run a short trip before it shuts down, 
and restart lasts only a few minutes (if that), that is a clogged sock 
or such.

Which are you experiencing?

FWIW, back in the early 80s even the 69s with the return line would 
vapor lock with the gas back then. Electric was the only cure for me. 
BUT, many are still running  with the mechanical pump YMMV. First check 
the air seal around the engine, so hot air exiting the engine is not 
drawn right back into the fan across the fuel lines.

Carry an iced beverage and pour over the fuel pump after a 10 minute 
stop. That got me back on the road more than a few times back then.

>My 62 sedan has a 140 hp engine running on two carbs. The trans is a PG. Currently I am experiencing extreme vapor lock. I make a short trip and my car is in trouble. It will start, run for a few minutes, and then stall. It will not restart until it has completely cooled again. Needless to write, this is really inhibiting using my car this summer. I am considering installing an electric fuel pump, but I would rather not. Any suggestions for dealing with vapor lock while retaining the mechanical pump?
