F150 GAS LEAKING

Engine Performance problem

I have a 1998 F-150 pick up and have changed the engine and now have a problem with gas leaking fom the #4 injector into the manifold. What can I do to fix this problem?

Release fuel pressure. See FUEL SYSTEM PRESSURE RELEASE . Disconnect negative battery cable. Disconnect vacuum hose from fuel pressure regulator. Remove fuel hose clamps.
Disconnect fuel supply and return line connections at fuel supply manifold. Disconnect fuel injector wiring harness connectors. Remove PCV hose.
Remove EGR valve-to-exhaust manifold tube. Disconnect EGR valve and EGR transducer hoses. Disconnect Vapor Management Valve (VMV) hose. Remove fuel supply manifold retaining bolts. Remove fuel supply manifold with injectors by pulling on injectors while using a rocking motion. Carefully disengage fuel injectors from supply manifold. To install, reverse removal procedure.
