So at idle, it may be pumping at a rate exceeding what you require at idle, creating excess pressure and subsequently heat. However, at WOT you may need that flow capacity. Some pumps provide a controller that allows you to reduce the current flow to the pump at lower rpm or loads when you don't need the fuel flow but are able to increase their flow capacity at WOT or higher load demands.

I understand that part, my questions comes from so many use the pump that in no way have the HP which needs that much flow. At best they may use 1/2 of what it can supply

Because its cool AD......:lolhit:.....and I agree, why spend 400 + for a A-1000 when a 130 dollar Holley will work in this case, maybe the OP gotta smokin deal on Aeromotive

The A-1000 leaves room to grow. If returning the fuel to the tank the pump nor the fuel is going to build any significant heat.
