Ford Motorsport F-Series Mass Air Install Instructions Pg 3 - Upper Intake Removal

This document is page 3 of 9 of the Ford Motorsport (Performance Equipment) F-Series Mass Air installation instructions, document number IS-M-9000-T51, dated 1/21/93. This page covers the 'Upper Intake Removal' portion of the mass air conversion procedure in seven steps: removing the throttle linkage cover (illustrated in Figure 2, which labels the throttle linkage cover, throttle cable, and automatic transmission kickdown cable), disconnecting the throttle cable linkage from the throttle lever ball and removing the linkage bracket, disconnecting the transmission control cable (automatic transmissions only), disconnecting the electrical connectors at the EGR valve sensor and idle speed control, disconnecting the throttle body coolant hoses (with a note that coolant may leak and hoses may need temporary plugging), and modifying the MAP sensor vacuum connection. Step 7 instructs the installer to cut the MAP sensor molded vacuum tree connector, discard the MAP sensor vacuum tree hose, plug the unused vacuum tree tube with the provided rubber plug, and leave the MAP sensor port open — emphasizing 'DO NOT CAP THE MAP SENSOR PORT!!!'. Figure 3 illustrates the MAP sensor/molded vacuum assembly, labeling the MAP sensor, harness connector, intake manifold vent, and where to cut and discard the hose.
