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.
