Removal Procedure

    CAUTION: Wear safety glasses when using compressed air in order to prevent eye injury.
    CAUTION: Remove the fuel tank cap and relieve the fuel system pressure before servicing the fuel system in order to reduce the risk of personal injury. After you relieve the fuel system pressure, a small amount of fuel may be released when servicing the fuel lines, the fuel injection pump, or the connections. In order to reduce the risk of personal injury, cover the fuel system components with a shop towel before disconnection. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.
    CAUTION: Place a dry chemical (Class B) fire extinguisher nearby before performing any on-vehicle service procedures. Failure to follow these precautions may result in personal injury.
    NOTE: Refer to Cover and Plug Openings Notice in CAUTIONS AND NOTICES .
    IMPORTANT: Always maintain cleanliness when servicing fuel system components.
