Fuel Line Fittings - R-Clip: Disconnect

WARNING: Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited, resulting in possible personal injury.

Before servicing or disconnecting any of the fuel lines or fuel system components, the fuel system pressure must be relieved to prevent accidental spraying of fuel, causing possible personal injury or a fire hazard.

CAUTION: Do not use any tools. The use of tools may cause a deformity in the clip components which may cause fuel leaks.

Relieve the fuel pressure. For additional information, refer to FUEL SYSTEM PRESSURE RELEASE .
