[DeTomaso] efi horse power gain

I understand the logic for the separate surge tank, but Aeromotive is one of the big guns in high power EFI fuel systems, and they don't seem to talk about the separate tank.  They do make a big deal about mounting the high pressure EFI pump in the fuel tank and one of their tech guys told me that the pump works better and longer submerged in the tank.

Ah, yes.... another person doing IR EFI on a GT40. Let us know how you  
get on!
Jack Houpe, Mike Trusty and myself all have a TWM setup with a TEC3r  
(Jack uses a TEC2) on our GT40's.

Each one of us attacked the twin tank fuel feed setup differently. I  
need to re-plumb my fuel system. I have a 'better idea' than what I am  
using now.
