[DeTomaso] efi horse power gain

[Kirby Schrader]

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.
