Overview

The MODE Auto Concepts Fuel-It BMW F Chassis N55 Walbro Stage 3 LPFP Upgrade is a complete Low Pressure Fuel Pump (LPFP) upgrade designed for customers needing additional capacity for their power goals. It uses a stock primary pump to maintain intended EKP operation and prevent current draw errors.

The upgrade includes a new BMW LPFP bucket with a new secondary pump assembly, a secondary wiring harness, and a Walbro filter. You can choose between a Walbro 450 (F90000274) or an optional Walbro 525 (F90000285) pump. A Hobb's switch is recommended to trigger the secondary pump under high boost conditions.
Show original supplier description
The Fuel-It BMW F Chassis N55 Walbro Stage 3 LPFP Upgrade from MODE Auto Concepts is engineered to provide the enhanced fuel delivery required for increased power output on pump gas, race gas, or E85 fuel. This 'New Build' option includes a brand-new BMW LPFP bucket and a secondary pump assembly, eliminating the need for a core deposit. You have the choice between a Walbro 450 (F90000274) or an upgraded Walbro 525 (F90000285) pump, both ensuring ample fuel flow. The kit comes complete with a secondary wiring harness and a Walbro filter. A crucial aspect of this upgrade is its operational design: the primary pump utilizes the stock unit to ensure the EKP functions as intended by the factory, thereby preventing potential current draw errors. To optimize this, the use of a Hobb's switch is strongly recommended to activate the secondary pump precisely when needed. Recommended accessories for this upgrade include a Lock Ring Removal Tool and a Hobb's switch. The kit is compatible with a range of BMW F-Chassis models, including the 1' F20, 1' F21, 2' F22, 2' F87 M2, 2' F23, 3' F30, 3' F31, 3' F34 GT, 4' F32, 4' F33, and 4' F36 Gran Coupé, with specific model year ranges provided for each. For optimal performance and longevity, it should be triggered under high boost conditions, ideally with a Hobb's switch.
