Frequently Asked Questions
SKU: Fulfilled by Fuel-It!
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 OEM 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.
(Unlike other similar looking kits we use high quality OEM buckets and float assemblies for assembly ensuring trouble free operation long term)
***Note: This system requires you to run one of our port injection kits and our external fuel pressure regulator upgrade***
This upgrade includes two Walbro 450 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 and is boost referenced.

-Due to the different configurations available, these kits will be built after the order is placed and will ship within 5-7 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.
