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 and is boost referenced.

• A complete plug and play solution by simply replacing your stock bucket.  However, to utilize the secondary, an additional wiring harness must be installed.
• Two new Walbro filters
• A custom fitting that is tuned to optimize the venturi and pump output
• Spare vent tube clip
• Wiring harness for the secondary pump
• All the necessary -6an fuel lines to connect the pumps, fuel filter, HPFP, and port injection rail
• 6 micron E85 compatible fuel filter
• Flow testing prior to shipping
• Two new E85 compatible Walbro 450 pumps (F90000274)
• Optional upgrade to Walbro 525 pumps (F90000285)

Additional Requirements

When you are ready to utilize the secondary on this assembly the following must be installed as well

• Return kit
• Port injection kit

• Lock Ring Removal Tool
• Hobb's Switch
• This option is for those customers that will be using a boost referenced switch to trigger the secondary pump. 

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)
