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 more flow than stock one and this assembly can be purchased one of three ways to meet your needs.

• Included with this kit:
  
• New BMW LPFP bucket that is upgraded with a new Walbro 450 pump and filter.
• A complete plug and play solution by simply replacing your stock bucket
• A new E85 compatible Walbro 450 pump (F90000274)
• Optional upgrade to Walbro 525 pump (F90000285)

• 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.

Compatible with the following production dates

• Z4 E89 (01/2008 — 08/2016)
