Which Aeromotive 340 Fuel Pump?


Aeromotive now sells 11140, 11141 and 11142 fuel pumps with 30% more flow than a Walbro 255 lph that can be mounted in-tank.

The 11140 has both the inlet and outlet centered.
The 11141 has an offset inlet and a centered outlet.
The 11142 has both an offset inlet and outlet that are in-line with each other.

Which one would be the one to use for the Turbo Trans Am?
Assuming I can make about 550 to 600 hp at the flywheel, would I be better off using a double pumper? If so, who sells them?
