Quick-connect (push-type) fuel line fittings must be disconnected using the proper procedure or the fitting may be damaged. There are two types of retainers used on the quick-connect fittings. Line sizes of3/8and5/16in. diameter use a hairpin clip retainer. The1/4in. diameter line connectors use a duck-bill clip retainer. In addition, some engines use spring-lock connections, secured by a garter spring, which require Ford Tool T81P-19623-G (or equivalent) for removal.
