RPG Plug and Play CAN Flex fuel kit

This is a plug and play CAN bus flex fuel kit, designed for seamless integration with our Pro tune upgrade.

If you've been considering upgrading to a true flex fuel system, now is the time! This fuel kit, in conjunction with our professional Protune, empowers your vehicle's ECU to precisely measure the fuel's ethanol content in real time. This allows for dynamic and automatic adjustments to your engine's tune, optimizing performance and efficiency based on the fuel blend.

This system is compatible with both naturally aspirated (NA) and boosted vehicles, offering a versatile upgrade for a wide range of applications.

*NOTE boosted vehicles will still require aftermarket fuel system as previously required 

This works on all 2015-2023 Ford Mustang GTs, Mach 1s, and GT350s. Will also work on 15-23 F150s with a return style fuel system. Our fuel lines are not compatible with F150s.

If using for an aftermarket fuel system for boosted setups, please select your year model and choose the options Yes/No below for 'Aftermarket Fuel System'. This simply removes the fuel lines from the kit as these are for stock fuel rails/NA applications only. 

We recommend purchasing one of the following Flex Fuel Sensor bypass blocks for you to use this kit on your return style fuel system: 

Motion Raceworks Flex Fuel Sensor Mount

Radium Engineering Flex Fuel Sensor Mount

Kit Includes:

• Custom Wiring Harness
• New 3/8 Plug and Play Fuel Lines for stock fuel rail/fuel system
• Genuine GM/Continental Flex Fuel Sensor
• Tube of Super Lube (1)
• CANbus Flex Fuel Analyzer
• Zip ties

This kit requires our Pro-Tune upgrade as well to function correctly!
