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.
1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief (With CH 48027) Fuel Pressure Relief (Without CH 48027).
2. Connect the CH-48027-1 (1) to the CH-48027-2 (2).
3. Remove the shop towel from around the fuel rail service port, and place in an approved gasoline container.
4. Perform any tests and/or diagnostics as needed. For the proper usage of the CH-48027, refer to the manufacture's directions.
