Fuel Pump

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.
