Attention! When working on the fuel system, you must first remove the pressure in the system.
1. Disconnect the negative battery terminal.
2. Place an appropriate container under the location where the system will be disconnected.
3. Slowly loosen the fuel line union nut to relieve pressure in the fuel system. An alternative method of relieving fuel system pressure is to remove the fuel pump fuse or fuel pump relay and run the engine at idle to a stop.
4. After completing work on the fuel system, install the previously removed fuse or relay.
