Notice:
The number 3 Fuel Tube must be positioned behind the number 1 Fuel Tube to eliminate interference with the Upper Intake Manifold plenum when
installed. See Figure 2.
4.
Insert the MFI Fuel Meter Body into the Fuel Meter Body Bracket on the Lower Intake Manifold being careful not to bind the Fuel Tubes. Make
sure that the number three Fuel Tube is routed in behind number 1 and 5 Fuel Tubes as shown in Figure 2. Push down firmly on the fuel meter
body locking it into the bracket.
Notice:
Use caution when inserting injectors into lower intake manifold to be sure the correct injector is being placed into the correct hole.
Injectors should not be removed once they have been installed.
Removal of injectors from the intake manifold may cause damage to the retaining lugs on the injector.
Important:
The Injector holes are numbered on the Lower Intake Manifold. The injectors are numbered on the side of the Fuel Meter Body.
5.
Insert the number 3 injector into the correct Injector hole in the Lower Intake Manifold first. Install the number 5 injector next and then number 1.
This sequence must be followed correctly to prevent interference of the Fuel Tubes. Injectors 2, 4, and 6 are then installed.
6.
Insure that the electrical connectors of the injectors are positioned so that they do not interfere with each other and are pointing towards the center
of the Intake Manifold. If necessary, rotate the electrical connectors inboard.
Notice:
Lack of lubrication will make installation of the Upper Intake Manifold plenum difficult and may cause damage to the 0-ring.
7.
Lubricate the Fuel Meter Body Upper Manifold 0-ring (orange in color) with clean engine oil.
8.
Inspect the Upper Intake Manifold plenum gasket and replace if necessary. Reinstall the Upper Intake Manifold plenum following the procedures
outlined in the Service Manual.
Important:
Lubricate the Fuel Inlet and Return Lines with clean engine oil before inserting them into the Fuel Meter Body.
Make sure that the Fuel Line Retaining Bracket is properly oriented with the tabs down.
