2. Insert a new retainer (A) into the connector (B) if the retainer is damaged, or after
- replacing the fuel rail.
- replacing the fuel feed line.
- replacing the fuel pump.
- replacing the fuel filter.
- replacing the fuel gauge sending unit
- removing the retainer from the line.
3. Before connecting a new fuel tube/quick-connect fitting assembly (A), remove the old retainer from the mating line.
4. Align the quick-connect fittings with the line (A), and align the retainer (B) locking pawls with the connector (C) grooves. Then press the quick- connect fittings onto the line until both retainer pawls lock with a clicking sound.
NOTE: If it is hard to connect, put a small amount of new engine oil on the line end.
5. Make sure the connection is secure and that the pawls are firmly locked into place; check visually and by pulling the connector.
6. Reconnect the negative cable to the battery, and turn the ignition switch ON (II). The fuel pump will run for about 2 seconds, and fuel pressure will rise. Repeat two or three times, and check that there is no leakage in the fuel supply system.
