Yeah i have a 4agze it runs a Supra twin turbo feeding engine custom bent XR8 fule lines and a modified pick up in the tank,Swirl pot is in boot with a vl turbo pump used as a lift(In boot aswl).It runs that big 8mm red hose with the 3sgte injectors and the microtech probably a bit overkill but it never surges/Leans out ever and does not leak anywhere.When the engine was standard it was not so bad and i never had issues till i got the microtech and 3sgte injectors,Reace Can you post up a pic of your box job if possible ? Is it vented? Thanks
