Yellow Truck & Vapor Lock

Paul, wanted to thank you for the input you gave me on my thoughts about EFI.  You showed where you put a pressure regulator and a routed your fuel supply and return up the passenger frame rail
Got me to thinkin, what does a EFI have that I don’t have which would help with my Vapor Lock problem and the main thing I could see was the fuel return line, and following your idea of running it up the fire wall rather than the usual in front of the engine.  Guys still tell me that EFI is still the way to go, but I decided to just put a return and use the Holley 65# Pump and filters and a regulator (with a return) to drop back down to 5# before I go and invest in a throttle body.  Well I had the ole girl out in 90+ weather in some traffic an never a hint of vapor lock even with my hood shut, so my confidence is up.  If I ever decide to go EFI I just need to pull the regulator and plumb directly.
 Thanks everyone who passed on their experience and ideas…….Bill

Bill,

Glad that worked out. Very nice you didn't have to go to all the trouble and expense to put in EFI to solve that problem without having another reason pushing you in that direction.  I've thought about EFI, but the carb is running really nicely, and there are other things that would provide a better driving experience.

BTW I think your new setup looks pretty sharp, too. I'm glad after all the help I've gotten here to be able to offer a useful idea to someone else.
