Fuel Line Coupler: Description and Operation
The two types of quick-connect fuel line couplings are called push connect fittings and metal spring lock connectors.
Push connect fittings consist of a tube (with a formed bead), a body, O-rings, retainer, and safety retaining clip (redundant). The fittings are disconnected
and connected by use of special tools.
Spring lock fittings have a bead formed in one tube that is retained by a garter spring inside a cage on the other tube. Sealing is by O-rings on the cage
side. These couplings are connected by pushing the two sides together until the garter spring clicks. They are disconnected by the use of special tools.
This type of connector is used for fuel tube-to-engine fuel manifold connections and sometimes for fuel filter connections. A tether is used for additional
protection on spring lock connectors. It must be unclipped before disconnecting.
