I will save you the time calling Aeromotive. I spent hours talking to them two years ago.
1) Put the pump as close to the tank as possible.
2) Put the pump level with the bottom of the tank so gravity will feed it.
3) Use -12 feed line to fuel rail and make sure the filter is the -12 opening and not the -10
4) Use as big as you can for the return
5) Use a controller for the pump/pumps.
6) Insulate lines from heat.
7) Use a sump in the tank.
8) Return line needs to spray fuel into the top of the tank not into the gas. let it hit the side of the tank and run into the fuel so air will cool it.
9) Run as big a vent as possible.
IMO.....Most aftermarket pumps are not made for continious duty use on the street without a controller. Every drop of gas in your tank goes to the engine bay about every 12 minutes. That is where the heat comes from unless you have cavitation from some other reason. The pump will get loud from cavitation, fuel pressure will vary and the pump will eventually shut off and you will be standed until it cools or you put fresh gas is to cool it.
