- Contains a wide variety parts and accessories going up to the engine for a complete fuel system kit
- Includes 20ft of 6AN nylon braided hose, enough to go from the tank to the fuel rails
- Simplifies your fuel system with direct replacement components while still maintaining an OEM-like appearance
- Takes the guesswork out of piecing together fuel fittings and hose, while also upgrading the factory fuel system
- Utilizes as many of the original sheet metal and chassis fuel system routing provisions with minimal to no drilling required
- Electric Fuel Pump Harness & Relay Wiring Kit, ensures the fuel pump receives the proper amperage, for improved reliability and consistent performance
- Pre-calibrated fuel level sending unit works with factory fuel gauge, for a simplistic installation, no guessing what ohm range your gauge or sending unit is
