to replace or service an induction system consisting of a carburetor and conventional intake manifold (as well as basic wiring
skills for the installations of the ECU).
Adequate skills for modifying the vehicle fuel supply are critical, and will vary widely, depending upon the selected components
and methods of fuel line plumbing. The most basic level will require the user to plumb a high-pressure supply fuel line and a
tank return fuel line to the fuel rails. The most complex level may require the user to modify the fuel tank, re-route or add fuel
lines, or mount various combinations of electrical and/or mechanical fuel pumps. Some fabrications may be required, depending
on applications, for throttle cable assemblies, throttle cable bracket and thermostat housings.
NOTICE:
If you are not absolutely certain that you have the skills and experience required to perform these
procedures, we strongly recommend you have this system installed and tested by a technician with
specialized training in EFI and fuel systems service.

7.0 MPI PRO-JECTION SYSTEM OPTIONS
MPI PRO-JECTION systems offer several optional brackets and spacers designed to simplify installation in certain applications.
These parts can be ordered separately by contacting our sales department. (See figures 17-21 for dimensions and applications.)
8.0 PLANNING THE INSTALLATION
Before starting the installation of the MPI PRO-JECTION system several things must be decided.
• Mounting location of the fuel pump
• Mounting location of the 10u fuel filter
• Routing of the fuel supply line from the tank, to the filter, to the pump.
• Routing of the high pressure fuel supply line from the pump to 10u fuel filter to the fuel rails on top of the manifold
• Routing of the fuel return line from the pressure regulator to the fuel tank.
• Mounting locations of the power relays and the ECU
• Proper throttle cable installation
• Proper thermostat housing clearance
9.0 REMOVAL OF EXISTING FUEL SYSTEM
1 - Disconnect the ground side of battery.
2 - Drain cooling system
3 - Remove cooling system hoses and thermostat housing.
4 - Drain fuel tank, then disconnect fuel supply line or disconnect fuel supply line and plug the hose.
