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 strainer
- replacing the fuel tank
- replacing the fuel fill pipe
- replacing the breather joint pipe
- it has been removed from the pipe
- it is damaged
  NOTE: When you replace a retainer, use the same size and manufacturer as the original retainer.

Before connecting a new fuel tube/quick-connect fitting assembly, remove the old retainer from the mating line.
Align the quick-connect fittings with the line (A), and align the retainer locking tabs (B) with the connector grooves (C). Then press the quick-connect fittings onto the line until both retainer tabs lock with a clicking sound.
NOTE: If it is hard to connect, put a small amount of new engine oil on the line end.

When you reconnect the connector (A) with the old retainer, make sure the connection is secure and the tabs (B) are firmly locked into place; check visually and also by pulling the connector. When you replace the fuel line with a new one, make sure you remove the ring pull (C) upwards after you confirm the connection is secure.
NOTE: Before you remove the ring pull, make sure the fuel line connection is secure. If the connection is not secure, the ring pull could break when you try to remove it.

Reconnect the negative cable to the battery, and turn the ignition switch to ON (II) (but do not operate the starter motor). The fuel pump runs for about 2 seconds, and fuel pressure rises. Repeat this two or three times, then make sure there are no fuel leaks.
