FUEL SYSTEM PRESSURE RELEASE
| WARNING | ALWAYS relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components. |
Unplug inertia switch, located on right kick panel, just forward of door. Crank engine for approximately 10 seconds. If engine starts, run it until it stalls, then crank engine an additional 5 seconds. Reconnect wiring to inertia switch. Disconnect negative battery cable.
Spring Lock Coupling
- Release fuel pressure. See FUEL SYSTEM PRESSURE RELEASE under FUEL SYSTEM. Place indicated spring lock coupler over coupling. See SPRING LOCK COUPLER IDENTIFICATION table. To release female fitting from garter spring, push coupler along tube into coupling. (Scheme 4)
- Pull spring lock coupling apart. Remove coupler from disconnected spring lock coupling. Check for damaged garter spring and "O" rings. Wipe end of lines with clean cloth.
- To install, place NEW "O" rings onto tube. Lubricate ends of lines with clean refrigerant oil. Locate White indicator ring (if equipped), which may have slipped down length of tube. Insert White indicator ring into cage of male fitting.
- Push fitting together with a slight twisting motion. White indicator ring will pop free of cage to indicate that male fitting is properly seated over flared end of female fitting.

INJECTION PUMP
| CAUTION | Fuel system contamination will damage finely machined parts within injection pump and injector nozzles. Clean fittings with fuel oil or solvent and blow dry with compressed air before disconnecting fuel lines. Cap all open fittings. Injection pump can be severely damaged if engine is washed or steam cleaned while engine is hot or running. |
