E-series 135i & 335i (N54 N55) LPFP Stage 2 upgrade



E-series 135i & 335i (N54 N55) LPFP Stage 2 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.

  • 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 R2100 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 R700 should you elect to return your *stock bucket.
      •  Rebuild:
        • If you'd prefer to send your *stock bucket in to be rebuilt/upgraded and avoid the core deposit, this is the option for you.  If you choose this option, your order will ship within 1 business day of receiving your *stock bucket.
        • All three options include the following:
          • A complete plug and play solution by simply replacing your stock bucket
          • A new E85 compatible Walbro F90000267 (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
