Fuel Vaporization Using Eddy Carb -- In-Line Fuel Pump Question

A couple thoughts. Aluminum carbs tend to be a little worse than zinc for hot restarts. If you get a Holley, stay away from the aluminum bodied versions. E10 gas makes anything harder to hot-restart, try some non-ethanol gas if available in your area.

This helped the heat soak on my Wagoneer, which had underhood temps somewhere near the surface of the sun. http://www.summitracing.com/parts/MRG-97/

If you use an electric pump, don't feed through the mechanical, bypass it. If the mechanical pump fails, the engine will keep running and the crankcase will fill with gasoline remarkably quickly.
