Removal & Installation (5.0L Engine)
Disconnect battery negative cable. Remove fuel tank and pressure relief valve caps. Install EFI Pressure Gauge (T80L-9974-A) at pressure relief valve and depressurize fuel system. Remove upper intake manifold and throttle body assembly.
NOTE:Always use new "O" rings during coupling installation.

Disconnect crossover fuel hose using Spring Lock Coupler (T81P-19623-G; T83P-19623-C for 5/8" line). Install coupler over coupling. See Fig. 15 and Fig. 16 . Push coupler along tube, and into coupling, to release female fitting from garter spring. Pull spring lock coupling apart. Remove coupler from disconnected spring lock coupling.
Disconnect fuel supply and return line connections at fuel supply manifold. See PUSH-CONNECT FITTINGS in this article for proper removal. Remove 2 fuel supply manifold retaining bolts. Carefully disengage fuel supply manifold from lower intake manifold.
To install, reverse removal procedures and tighten fuel supply manifold to 15-22 ft. lbs. (20-30 N.m). See Fig. 5 .
