Connection
WARNING: Do not smoke while working on the fuel system. Keep open flames away from your work area.
1. Check the pipe contact area for dirt and damage, and clean if necessary.
2. Insert a new retainer into the connector if the retainer is damaged, or after
- replacing the fuel pump.
- replacing the fuel feed pipe.
- removing the retainer from the pipe.
3. Before connecting a new fuel tube/quick-connect fitting assembly, remove the old retainer from the mating pipe.
4. Align the quick-connect fittings with the pipe, and align the retainer locking pawls with the connector grooves. Then press the quick-connect fittings onto the pipe until both retainer pawls lock with a clicking sound. If it is hard to connect, put a small amount of new engine oil on the pipe end.
5. Make sure the connection is secure and the pawls are firmly locked into place; check visually and by pulling the connector.
6. Reconnect the battery negative cable, and turn the ignition switch ON (II). The fuel pump will run for about two seconds, and fuel pressure will rise. Repeat two or three times, and check that there is no leakage in the fuel supply system.
