Precision Raceworks "Gauntlet" HPFP Upgrade - BMW N55

The Gauntlet is Precision Raceworks' high-pressure fuel pump upgrade for the N55, built to flow well beyond the factory pump's limits for owners pushing past stock power levels. It drops into the factory location with a plug-and-play install, so there's no permanent modification standing between you and a return to stock later if you ever need it.
Why Upgrade
Precision Raceworks rates the Gauntlet at 70% more fuel flow than the stock N55 high-pressure pump, supporting fuel rail pressures up to 240 bar. It's built around a cast stainless steel housing with a Teflon-lined low-pressure inlet tube and a stainless steel high-pressure outlet tube, and Precision Raceworks backs it with over 60,000 miles of on-road validation alongside dynamic bench testing across pump gas, E85, and blended fuels.

Installation Notes
Retuning is required to take advantage of the added fuel flow; Precision Raceworks builds and validates the Gauntlet for use with EcuTek, Bootmod3, and MHD. If you're building toward E85 or higher power levels, pairing this with a low-pressure fuel pump upgrade, such as Precision Raceworks' high-performance low-pressure fuel pump for F-series N55, keeps the fuel system balanced end to end.
