I've been following Ken Henderson and Dennis' blog of their trip out west and was sad to read that Ken had some vapor lock problems a couple times and some serious problems coming up out of Death Valley.

Ken's coach is what I consider a PERFECT GMC. He's done everything to a very high degree of mechanical perfection and has EFI on the CADDY. If he's having vapor lock issues it doesn't bode well for my stock carb if we make the Route 66 run next summer.

I understand that vapor lock happens when gas boils in the lines or carb. But since Ken has EFI, I assume it's boiling in the lines. And since I'm pretty sure that Ken's fuel pump is back by the tanks and is a 'pusher', does that mean it is boiling BEFORE the pump or can it still boil after the pump when it's under pressure? Or is it actually boiling between the tank and the pump? I have a hard time imagining that it is boiling INSIDE the tank????

Has anyone tried having a small fuel cell INSIDE the air conditioned space of the cab to keep a few gallons cool before being pumped to the fuel system?
