This is a complete Low Pressure Fuel Pump (LPFP) upgrade for those customers that need the additional capacity to meet their power goals on pump gas, race gas, or E85. It utilizes a stock pump for the primary pump so that your EKP operates as intended by the factory eliminating potential errors for current draw and the secondary pump then runs under high boost only. For power levels up to 700whp we'd recommend using the standard 450 pump and beyond 700whp we'd recommend upgrading to the 525 pump. F-Series B58 (Gen 1) Stage 3 assemblies include: New stock LPFP Secondary pump assembly Secondary wiring harness Walbro filter Walbro 450 pump (F90000274) Compatible with the following vehicle production dates: 1' F20 LCI (05/2014 — 06/2019) 1' F21 LCI (05/2014 — 06/2019) 2' F22 (06/2014 — 06/2017) 2' F22 LCI (09/2016 — 12/2019) 2' F23 (06/2014 — 06/2017) 2' F23 LCI (09/2016 — 12/2019) 3' F30 LCI (09/2014 — 10/2018) 3' F31 LCI (09/2014 — 06/2019) 3' F34 GT LCI (09/2015 — 12/2019) 4' F32 (04/2015 — 02/2017) 4' F32 LCI (05/2016 — 12/2019) 4' F33 (03/2015 — 02/2017) 4' F33 LCI (05/2016 — 12/2019) 4' F36 Gran Coupé (05/2014 — 03/2017) 4' F36 Gran Coupé LCI (05/2016 — 12/2019) *Note: Secondary pump can NOT run full time. We recommend using a Hobb's switch to trigger the secondary under high boost. See the installation process here: https://www.youtube.com/watch?v=YoPf0F7PBt8

This is a complete Low Pressure Fuel Pump (LPFP) upgrade that replaces your weak stock LPFP assembly with a high-flow E85-certified one. Standard Kit Includes: A brand new OEM LPFP bucket that is upgraded with a new Walbro 450 or 525 pump and filter. A new E85 compatible Walbro 450 pump (F90000274) that flows 50% more fuel than stock Optional A new E85 compatible Walbro 525 pump (F90000285) that flows 65% more fuel than stock NOTE: Owners with I-Drive may get a Fuel pump warning on the screen that says "Continued driving is possible. Have the system checked by your BMW center as soon as possible." As long as the car is running fine and does not exhibit any other symptoms, there is not an issue with the pump and this can be ignored. If you have any questions about this please feel free to contact us. Upgraded pumps pull more current, so if your EKP (LPFP control module) is weak, it may overheat causing it to shut down and need to be replaced. If this is a concern for you check out our Stage 3 fuel pump upgrade kits that retain the stock LPFP and add a secondary pump.
