Quick Connect Fitting: Installation

CAUTION: Never install a quick-connect fitting without the retainer being either on the fuel tube or already in the quick-connect fitting. In either case, ensure the retainer locks securely into the quick-connect fitting by firmly pulling on fuel tube and fitting to ensure it is secured.

Using a clean lint free cloth, clean the fuel tube nipple and retainer.
Prior to connecting the fitting to the fuel tube, coat the fuel tube nipple with clean engine oil.
Push the quick-connect fitting over the fuel tube until the retainer seats and a click is heard.
The plastic quick-connect fitting has windows in the sides of the casing. When the fitting completely attaches to the fuel tube, the retainer locking ears and the fuel tube shoulder are visible in the windows. If they are not visible, the retainer was not properly installed. Do not rely upon the audible click to confirm a secure connection.
