Ford Fuel Line Spring Lock Coupling Disconnect & Fuel Supply Manifold Removal

This is a scanned page from a Ford service manual covering the removal of the Fuel Supply Manifold Assembly and the procedure for disconnecting and connecting fuel line spring lock couplings. The removal steps direct the technician to perform Steps 1-4 under Fuel Charging Assembly, remove the upper manifold assembly, relieve fuel pressure (referencing Section 24-50, Fuel Tank and Lines and Fuel Evaporative Emission Control System), and use Quick Disconnect Tool D87L-9280-A (3/8 inch) or D87L-9280-B (1/2 inch) to disconnect the fuel chassis inlet and outlet hoses. An illustrated four-step disconnect procedure shows fitting the tool into the cage opening, pushing it in to release the female fitting from the garter spring, pulling the couplings apart, and removing the tool. The four-step connect procedure covers inspecting/replacing garter springs (E1ZZ-19E576-A for 3/8 inch, E1ZZ-19E576-B for 1/2 inch), cleaning fittings and replacing O-rings (390846-S96 for 3/8 inch, 390847-S96 for 1/2 inch, two per fitting, brown fuel-resistant only), lubricating O-rings with clean engine oil, assembling with a twisting motion, and verifying engagement by pulling on the fitting to confirm the garter spring seats over the flared end of the female fitting.
