Wow, Charles, that is not a good situation for Texas owners!!!! I wonder if a TPI is an only real solution. An expensive one at that. However a new NON Quadrajet Carb may be a thought.

I had a marine fuel/water separator that I removed when
I eliminated the manual fuel pump. The reason I removed
it is that, where it was located there was about 8 to 10
more feet of fuel line with it installed. Fuel tanks have been
cleaned and sealed. Pick up and sending units replaced.
All the fuel lines and filters have been replaced. I have
also tried different electric fuel pumps. Even went so far
as to try an 8 PSI pump only to flood the carburetor when
I turned it on. I am not the only one having this problem.
Others in the area are having the same problem. One
added second electric pump, so when he switches tanks
the second pump activated. Another just completed
dropping tanks, replacing lines and filters. Little or no
change. Around 100 degree temperatures, we all have
the exact same problems Denny described. The only thing
I have seen mensioned on the list that I have not done or
tried is insulating the fuel tanks.
Still looking fo answers.
Charles
