Our custom E85 Flex Fuel kit for the 10-15 5th Gen Camaro SS & ZL1 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 includes the following:

  • 1 - GM OEM Flex Fuel Sensor
  • 1 - Stainless Steel Braided PTFE OEM Style Fuel Line (Made in the USA)
  • 1 - Gen5DIY custom plug & play power harness & ECU tap. (Made in the USA)
  • Fuel Disconnect Tool (Design and brand may vary)
  • 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 out video most people will not even know your car is setup for flex fuel.


  • This kit will not work with a 5th Gen Camaro ZL1 without fuel system upgrades. Speak to your builder/tuner on what is required for a ZL1 application beyond the flex fuel kit. 
  • The 5th Gen 2012-2015 Camaro ZL1 will need fuel system upgrades to support E85. Suggested Upgrades: Injectors and at minimum an auxiliary fuel pump.
  • The 5th Gen 2010-2015 Camaro SS has the ability to run E85 with just this kit. But your stock fueling system will be maxed out. Consider fuel system upgrades if you plan to build your LS3 or L99 beyond bolt-one’s. 
  • This kits harness uses OEM connectors in tandem with OEM products. Fit and finish look 100% stock under the hood. A Camaro SS will pick up 10-15rwhp and a Camaro ZL1 will pick up 25-30rwhp 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.
