Fuel-It! Stage 2 LPFP — N55 / N20 (F-Chassis)
Fuel-It! Stage 2 low-pressure fuel pump for the F-chassis N55/N20 — a drop-in in-tank upgrade that feeds a Stage 2/3 build. The factory in-tank pump runs out of duty on E85 and higher boost, starving the high-pressure pump up top. This replaces the stock pump with an E85-rated Walbro.
What it is
A complete drop-in assembly with a Walbro 450 (about 50% more flow than stock); a Walbro 525 (~65%) is available. Single pump. Because it draws more current than stock, a tired EKP (the factory pump controller) can run warm on a hard-driven car — for sustained high-power/E85 use, step up to the dual-pump Stage 3.
Where it fits in the build
Low-pressure (in-tank) side; it keeps an upgraded high-pressure pump fed. We tune the engine to the fuel system.
Fitment
F-chassis N55/N20 — F20/F21, F22/F23, F87 M2, F30/F31, F32/F33. Confirm your chassis in the selector.
