Quick-Connect Fitting Operation

Note: Fuel injection quick connect fitting "O" rings, spacers, and retainers must be replaced each time a quick connect fitting is disconnected.

Removal

1. Disconnect the Quick-Connect fitting by pushing in on the plastic ring at the end of the fitting and pulling on the Quick-Connector. An open-end wrench may be used to assist in unlocking the fittings.
2. Once the Quick-connect fitting is disconnected, plug the fuel lines so that dirt and foreign particles do not enter the fuel lines.

Installation

Note: Before reassembling the Quick-Connect fittings, lubricate the fuel tube nipples with clean 30 weight engine oil.

2. Connect the Quick-Connect fuel fittings by pushing the fitting onto the fuel tube nipple. The fitting should snap into place when it is locked.

Note: After the Quick-Connect fuel fittings have been installed, the connection should be verified by pulling on the lines.
