Can't seem to run with a mechanical fuel pump without it stalling on me. Could be vapor lock but did the same thing with a electric pump. Installed a new 34ADF carb, mechanical fuel pump, fuel sending unit, blew out fuel lines, and replaced all rubber lines. Runs fine in the morning but driving home with temperatures in Vegas at 106 I get about 8-10 miles and it dies on me all of a sudden. Any ideas? :bang:

Installed a fuel pressure guage and was running 3 1/2 to 4 psi. Temperature here was 110 and I drove her about 10 miles in stop and go traffic. Started to sputter so I headed back home. Let her running and checked guage.....needle sitting at 0. Let her ideling for 5 minutes while I got a beer and she died on me. Today the electric fuel pump and fuel pressure regulator gets installed. The story continues tomorrow. Anyone with any ideas:idea:
