QUICK CONNECT FITTING REMOVAL/
INSTALLATION

• Clean around the quick connect fitting before [1]
disconnecting the fuel feed hose, and be sure that
no dirt is allowed to enter into the fuel system.
• Do not bend or twist the fuel feed hose.
Relieve the fuel pressure (page 7-4).
Disconnect the battery negative (-) cable (page 21-5).
Push the retainer tab [1] forward. [2]
Press down the retainer and disconnect the connector
[2] from the fuel pump joint/fuel rail. [1]

cover the disconnected connector and pipe end with
the plastic bags [3]. [2]
Press the connector onto the fuel pump joint/fuel rail
