Fore Innovations Fuel System Level 2 Dual Pump (E85-capable, 900+ HP support)

This replaces the fuel pump assembly inside the gas tank with a two-pump setup so the engine can be fed far more fuel than the single factory pump can deliver. It makes no power on its own; it is the supporting hardware that lets a big power adder or a switch to E85 actually get the fuel it needs.

why this one — Fore rates this Level 2 system for 900-plus wheel horsepower and states it is E85 capable, which puts it a step above the Level 1 dual-pump kit already in this list. Be honest with yourself about whether you need that much: at $2,088.45 it is far more pump than a stock or lightly modified 5.0L will ever draw on, and the E85 capability only pays off if a station near you actually sells E85. It is also a drop-the-tank job, so budget shop time on top of the part.
