Gen IV/V GM V8 Flex Fuel Kit

The DSX Tuning flex fuel kit offers the original plug-and-play solution for integrating flex fuel capability into Gen IV and Gen V GM V8 vehicles. This system empowers your vehicle to run on a spectrum from pure gasoline to pure ethanol, enabling you to unleash the full power potential of your setup. Ethanol, in particular, significantly benefits forced induction applications, and this kit allows for seamless transitions between fuels without manual monitoring or ECU reflashing. The kit prioritizes ease of installation with its 100% clip-together plumbing, eliminating the need for wrenches. This 8AN line features 6AN connections, ensuring true flow capacity of a 3/8" line without significant ID reduction at the hose end. An optional configuration is available without the replacement line, where the sensor still installs at the firewall, reusing the factory fuel line, though this may result in a slight kink due to the extended connection point.
