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 stock LPFP assembly with a new E85 certified one. The new Walbro 450 pump provides approximately 100% more flow than stock and this assembly can be purchased one of three ways to meet your needs.

Trade-in:
- This option allows you to receive a rebuilt/upgraded stock bucket with a new Walbro 450 pump, filter, and fittings to swap out your stock LPFP assembly. A $150 core deposit is included in the price that will be refunded when we receive your *stock bucket.
New Build:
- This option includes a new LPFP bucket that is upgraded with a new Walbro 450 pump, filter, and fittings. No core deposit is required but you are eligible for a core refund of $50 should you elect to return your *stock bucket.

Both options include the following:

A complete plug and play solution by simply replacing your stock bucket
A new E85 compatible Walbro 450 pump
A new Walbro filter
A custom fitting that is tuned to optimize the venturi and pump output
Spare vent tube clip
Flow testing prior to shipping
Recommended accessories:
- Lock Ring Removal Tool

To be eligible for a core return, the bucket must be completely stock and undamaged. (Pump itself does not have to be functioning)

+ International customers: Due to different emissions requirements, the top portion of your fuel bucket (top hat) is different and doesn't have a large vent tube connection. For this reason, we are no longer sending the top hat to international customers as this often causes confusion. Those customers will simply re-use their current top hat when installing their Stage 2 pump.

- All Stage 2 assemblies are stock buckets that have been rebuilt and may show signs of being disassembled and rebuilt. They are all flow tested and verified before being shipped.

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.

As these cars get older we're seeing more issues with the stock components and more demand for cost-conscious fueling solutions. The new Fuel-It 650HP line of fuel system upgrades are designed with those needs in mind while maintaining a budget. They make the most of the stock components to maintain stock reliability and drive-ability but when the boost gets cranked up, the Fuel-it 650HP components kick in to support the additional fueling needs of your high horsepower car. With the Fuel-It 650HP lineup, you can upgrade your components all at one time or upgrade them as time and budget allows. If upgrading one component at a time, we'd recommend starting with the LPFP first as that is the heart of your fuel system, without a good Low Pressure Fuel pump (LPFP) you can't supply the fuel needed to any of your other components. Your secondary pump can NOT run full time, it must only be run under boost only. Running it full time will place additional strain on the stock system, will lead to high fuel temps, and pump or component failure. To turn the secondary pump on under boost we recommend running the included 4psi Hobb's switch. Included with all S65 LPFP upgrades: Walbro 450 pump (F90000274) Black Anodized Custom fitting Pump brackets 9/64" terminals and associated hardware Fuel line Replacement PITA clip Wiring harness
