Our custom E85 Flex Fuel kit for the 2019-2023 6th Gen Camaro LT1 (V8) with PTFE GM fuel line is just what you need for more power, savings on fuel costs, and a better smelling ride... (Okay that last one is subjective). This kit is assembled by Lethal Garage and it includes the following:

  • 1 - GM OEM Flex Fuel Sensor
  • 1 - GM OEM PTFE Fuel Line 
  • 1 - Gen5DIY custom plug & play power harness with ECU tap.
  • Two Year Warranty on all GM parts as provided by GM & lifetime warranty on the Gen5DIY harness that covers any defects in craftsmanship.  

Our product is designed to tuck away and be hidden along side your vehicles power harness and lines. The harness is wrapped the same as the factory wires to allow it to blend in and not standout. When installed like our video most people will not even know your car is setup for flex fuel. 

Current Bonus Items:

  • Fuel Disconnect Tool
  • Free USPS Priority 2-4 day Shipping


  • This kits harness uses OEM connectors in tandem with OEM products. Fit and finish look 100% stock under the hood. Your car will pick up 20-30rwhp on e78 or better depending on the tune.
  • Note: While our flex fuel sensor can be installed and works perfectly fine to run pump gas with your Camaro without a tune, to run E85 your car 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.

Install Guide: 

Note: 20-23 Camaro's will have a different cover plate vs the grey pin shown in this video. The black cover or pin just needs to be removed or pushed out so you can pin the ECU to read the sensor.
