Ford Motorsport F-Series Mass Air Install Instructions Page 5 - Intake Removal

This is page 5 of 9 of the Ford Motorsport (Ford Racing / FMS) F-Series Mass Air conversion installation instructions, document number IS-M-9000-T51*, dated 1/21/93. It covers Steps 12 through 19 of the mass air meter installation procedure. The steps described include disconnecting the PCV hose from the PCV valve at the rear of the passenger side valve cover, removing the shield over the front two upper intake manifold bolts, removing the upper intake manifold hex head bolts, and loosening the middle intake bolt on the throttle body using a T40 TORX bit taped into a 1/4" socket with a 6" extension (illustrated in Figure 7 with Detail "A"). A note advises taping over the intake openings in the lower intake manifold. The page then instructs disconnecting the eight fuel injector connectors on the production harness (Figure 8, Lower Intake/Injector Harness), positioning the production fuel injector harness away from heat sources or sharp edges, locating the EEC-IV processor/60-pin connector on the driver's side firewall, and disconnecting the 60-pin engine harness connector from the EEC-IV processor (referencing Figure 9 on a subsequent page). Two exploded-view illustrations show upper/lower intake manifold and gasket removal and the injector harness location.
