Product Description

If you are making over 600whp and your LPFP pressures are dropping, this is the solution for you!

This is the most powerful LPFP upgrade available and it still utilizes the stock bucket and retains all the factory venturi's and fuel transfer systems in the tank while bypassing all the factory restrictions to maintain higher pressures and greater flows.

***Note: This system requires you to run port injection and an external fuel pressure regulator upgrade***

This upgrade includes two Walbro E85 pumps, a custom 6 micron ethanol compatible filter assembly, and all the -6an fuel lines and fittings to complete your upgrade.  This solution provides up to 300% more flow than stock, is boost referenced, and this assembly can be purchased one of three ways to meet your needs.

  • New Build: (North American Spec)
    • This option includes a new bucket assembly, float, and tophat.
  • New Build: (European Spec)
    • This option includes a new bucket assembly, float, and tophat.
  •  Rebuild:
    • If you'd prefer to send your *stock bucket in to be upgraded and avoid the core deposit, this is the option for you.  If you choose this option, your order will ship within 5 business days of receiving your *stock bucket.
  • All the options include the following:
    • A complete plug and play solution by simply replacing your stock bucket.  However, to utilize the secondary, an additional wiring harness must be installed.

*Note: An ethanol analyzer must be used in conjunction with the ethanol sensor to read your ethanol content.
There are three options to read your ethanol content when using our ethanol analyzers:

  • Bluetooth only
  • Bluetooth and JB4 integrated (0-5 Volt) 
  • Bluetooth and 50-150hz Raw Signal
    • Bluetooth (Iphone or Android app must be purchased to use this feature)

-Due to the different configurations available, these kits will be built after the order is placed and will ship within 5 business days.

- All Platinum LPFP assemblies are stock buckets that have been rebuilt and may show signs of being disassembled and rebuilt.

  • 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.
