Fuel-It! Stage 2 LPFP — N55 (F1x 5/6-Series & F30 Hybrid)
Sale price $825.00
Regular price
Fuel-It! Stage 2 low-pressure fuel pump for the larger F-chassis N55 — the 5 and 6 Series and the F30 ActiveHybrid 3. The factory in-tank pump runs short on E85 and boost; this drops in an E85-rated Walbro in its place.
What it is
A drop-in assembly with a Walbro 450 (~50% over stock); a Walbro 525 (~65%) is optional. Single pump. For sustained high-power/E85 use where pump current draw matters, consider a dual-pump setup.
Where it fits in the build
Low-pressure (in-tank) side; keeps an upgraded high-pressure pump fed. We tune the engine to the fuel system.
Fitment
N55 — F10/F11 535i, F06/F12/F13 640i, and F30 ActiveHybrid 3. Confirm your chassis in the selector.

WHY WE SHIP FUEL-IT!
Fuel-It! builds the LPFP and HPFP upgrades and the flex-fuel sensing kits that make running ethanol a clean, repeatable thing instead of a guess. Their ethanol-content sensing lets a calibration read actual blend in real time and adjust, which is what makes a flex-fuel build safe to daily. We use Fuel-It! parts where a customer wants the gains ethanol gives but needs the fuel system and the sensing to handle a tank that is never quite the same mix twice. It is the bridge between pump-gas reliability and the bigger numbers E-blends make possible.
