FUEL SUPPLY CONNECTION:
WARNING: THE FUEL RAIL AND/OR FUEL LINES ARE UNDER HIGH PRESSURE. USE
EXTREME CAUTION WHEN DISCONNECTING ANY FUEL LINE. QUICKLY COLLECT AND
PROPERLY DISPOSE OF ANY EXCESS FUEL SPILLAGE.
1. Located on the fuel rail (injector rail) is a “test port” fitting used by mechanics for checking fuel
pressure. This is usually covered by a black plastic cap and is where the red fuel feed line will be
connected. Note: Care should be taken to be certain the port you have selected is the “Fuel Test-Port”.
2. Remove the factory test port fitting and install the supplied Ford fuel rail adapter fitting (NX part #
16179) using NX red thread sealer. The adapter fitting is very thin so you should use very little torque
when tightening.
3. If you are using aftermarket fuel rails you may be required to use a “T” fitting to tap into your vehicles
fuel system. ONLY TAP INTO THE HIGH PRESSURE FUEL LINES! DO NOT TAP INTO A
RETURN LINE!
4. Now connect the red fuel line from the fuel supply to the inlet side of the fuel solenoid.
ELECTRICAL HOOK-UP:
1. Mount the toggle (Arming) switch in a location that is within easy reach of and in plain sight of the
driver.
2. Using 18-ga, blue wire and connectors supplied in the switch kit, connect a HOT lead (12 VDC
POSITIVE) to the “Power” terminal of the toggle switch. (Use 5 amp inline fuse if desired). This
power source must be controlled by the ignition switch (See wiring Schematic).
