Installation Notes and Tips

Before installation, verify compatibility with your specific Chevrolet or GMC truck model and engine configuration. Ensure the fuel system is depressurized to prevent fuel spray during removal. The quick-connect fittings allow for straightforward connection and disconnection; however, inspect the connectors for any debris or damage before assembly. Properly route the fuel line to avoid contact with hot engine components or sharp edges. After installation, check for leaks by pressurizing the fuel system and monitoring connections.
