Re: Overheating '67

I'm not so sure what adding extra pumps would do for a vapor lock problem. 
All an elecric pump would do is add heat to the fuel, which you don't want.
Unless the pump compressed the fuel somewhat and allowed for the heat to
dissapate into the surrounding air, that would work the same way as a
fridge operates, which is kind of what you want.

Just my 2cents.
