E89 Z4 Stage 2 LPFP Upgrade
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.
- 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.
