Fuel Problems with New Tank
I recently completed an installation of an aftermarket aft-axle tank in my 71. After driving the truck for a few weeks, I occasionally encounter a fuel problem. After sitting for 8-10 hours, the truck always starts easily. Once I drive it for awhile (and the engine warms up), I have difficulty restarting the truck once I turn it off and let it sit for 15-20 minutes. The truck usually drives great once started, but recently it stalled while driving (seemed to be starved of fuel).
I was thinking vapor lock, but I do have a venting cap (I tried two caps). I was considering adding an electric fuel pump?? Basically, I never had this problem until I switched location of tank. Any ideas? Thanks.

Fuel Problems with New Tank
Fuel line to small? Fuel filter to small? Weak fuel pump? Line running buy something hot? 3/8 inch ID line, 3/8 steel fuel filter in front of the pump, new mechanical pump (maybe a Mallory or Edelbrock). I personally don't like electric fuel pumps but sometimes they are necessary.

Fuel Problems with New Tank
Make sure your fuel line isn't getting pinched between the frame, body parts, etc. After I installed a 20 gal. tank in my 68 the engine would occasionally die on me at highway speeds. Wouldn't do it even when I reved the engine at rest or at slow speeds; just on the highway. I replaced the fuel pump, tore the carb apart a couple of times and I almost replaced the fuel pump eccentric. Ends up that the cab would shift slightly in the "highway wind" and pinch the rubber fuel line shut.
Just a suggestion.
