  • All Kits that do not pick the Motion Raceworks AN adapter mount will ship with a custom Teflon coated stainless steel braid fuel line.
  • This kit is designed to work with the factory fuel pump on naturally aspirated vehicles. If your vehicle has a blower or a turbo charger, talk with your builder to verify you have enough fuel pump and injectors to utilize E85.
  • This kits harness uses OEM connectors (Factory ECU) in tandem with OEM products. Fit and finish can look 100% stock under the hood. 
  • Note: While our flex fuel sensor can be installed and works perfectly fine to run pump gas with your LS motor without a tune, to run E85 your vehicle must have a tune to run E85 fuel. DO NOT INSTALL & RUN E85 WITHOUT A PROPER TUNE. Make sure your tuner has verified your sensor is hooked up and reading the ethanol content before adding e85 to your vehicle.
