2.7 Fuel Pressure Safety Switch Installation
1. Locate the fuel rail test port fitting.
2. Make sure the vehicle’s engine is cool. Release pressure in
the fuel system by pressing down on the valve in the center
of the fitting. Cover top fitting with a rag whicle releasing
pressure. This will allow the pressure to escape as well as
some fuel.
3. After relieving all pressure, remove test port fitting core and
install the 1/16 NPT male X 1/8 NPT female brass fitting in
its place, using liquid teflon paste.
4. Using liquid Teflon paste, install Fuel Pressure Safety Switch
into the 1/8 NPT female adapter end.
Note: On some vehicles, there is no test port fitting, or the
location of the test port fitting does not allow ample room
for the fuel pressure safety switch to be mounted. These applications will require a “Banjo Nut” at the fuel filter
to be drilled and tapped to allow mounting of the safety switch.
2.8 EFI Vacuum “Tee” Installation
1. Refer to the jet map and select the correct fuel jet for your
horsepower setting. Install the jet into the EFI vacuum tee,
between the tee and the blue anodized fitting. Tighten
fitting securely.
2. Remove the vacuum line from the vehicle’s fuel pressure
regulator.
3. Install the vacuum line that originally went to the vehicle’s
fuel pressure regulator onto the center barb fitting of the EFI
vacuum tee.
Note:
The center barb can easily be identified by the
anodized nut used to hold the Pressure Relief Jet.
4. Measure the correct length of vacuum line from the barb on
the Fuel Pressure Regulator to one port of the EFI Vacuum
Tee. Cut the vacuum line and install.
5. Measure the correct length of vacuum line from the barb fitting of the nitrous pressure regulator to the
remaining open port on the EFI Vacuum Tee. Cut the vacuum line and install.
6. Using the included hose clamps, secure all hose connections on the tee and regulators.
2.9 Fuel Pump Installation
Warning: Before performing any of these steps, relieve the pressure in the fuel system.
1. Locate the fuel filter on the under-carriage of the car. Disconnect the hard fuel line from the filter.
2. Install the fuel pump fittings into the fuel pump and find a secure and safe area to mount the fuel pump under
the vehicle within reach of the fuel filter.
3. Measure and cut a length of the supplied fuel hose from the outlet of the fuel filter to the inlet of the fuel pump.
Connect one end of the cut fuel hose to the barb fitting on the inlet side of the fuel pump and secure with one
of the supplied hose clamps.
4. Install the female Ford Fuel Hose Connector into the remaining end of the fuel hose and secure with one of the
supplied hose clamps. Connect the Ford Fuel Hose Connector to the outlet of the fuel filter.
