Fuel Hoses & Pipes: Notes

WARNING: This page is about a different car, the 2003 GMC Sierra and 2003 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: The Compressed Natural Gas (CNG) system operates at pressures up to 3600 psi (24820 kPa). Release fuel pressure before servicing CNG fuel system components in order to reduce the risk of fire and personal injury. See FUEL SYSTEM PRESSURE RELEASE . Natural gas is highly flammable. In order to reduce the risk of fire and personal injury, keep sparks, flames, and smoking materials away from the vehicle while you perform the CNG fuel system service.

WARNING: Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable(s). Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

NOTE: Combustible Gas Detector (J-45878) is required for this procedure. See Figure .
