I will be the first to tell you I am not an expert. I do not want to spread bad info around.

I am not the only one with this problem though. Lots of drag week guys have this problem. While my pump location could be the problem, and I do plan on moving it. But its my belief most of the problem is flowing 550-600HP worth of fuel but only using a small amount of it so a huge percentage is going back to the tank. Its going back to the tank after it has picked up heat from the 180* engine compartment.
