Jack, i had a old Ford truck that I towed a lot with here in AZ, in warm weather it gave me all kinds of hot weather driving problems, same deal, I installed larger fuel line, bigger race mechanical fuel pump, put a Holley red pump, and I finally got it to run some what better in AZ weather (110' to 115' weather) The problem ended up being.....the factory air cleaner...I had modified the engine with headers, cam....bla bla....but left the stock air cleaner including the fresh air tube.

Well a friend gave me a much larger air cleaner of a 460 that included all the fresh air system.....problem solved.....I took all the race pumps of and put a stock fuel pump back on it and never had another problem, oh yeah the engine I was using was a 400.
