I'm ordering my fuel system but am leaning towards the triple set up over the dual. I plan on running e85, so when is a triple fuel pump needed?
Depends on the combo and MAX HP Goals
You’ll be able to push that combo with that blower, injector and E85 to about 1100rwhp, and that’s with a Fore triple pump (Walbro high pressure F90000274s).
They now have 2 higher flowing pumps (F90000285/295) but the injector is done around there (1050-1100rwhp SAE) even with the best pumps.
I have personal experience with you exact combo, it rips so have the fuel system ready.

Check out Fore Innovations. Some of, if not the best return fuel systems and components for Ford Mustang/Cobra/GT500.Thank you all for the input! Triple pumps it is, I just got confirmation from lethal that their division X fuel Rails do not fit with the Gen 5 3.9 whipple, so what are my options??
