23. Inspect the OEM fuel supply line o-rings and replace if necessary. Place a light coat of oil on the fuel
supply line o-rings and the supply line adapter fitting to ease installation. Connect the AN-08 tee
adapter fitting to the OEM fuel supply line.
24. Connect one AN-08 90-degree hose end to the front of each fuel rail. Plan a route for each of the two
lines between the fuel supply tee adapter and the fuel rails, measure the two lengths of fuel line
needed. See section titled Hose and Fitting Assembly for fuel line assembly instructions. Once the
hoses are assembled, ensure there is no debris in the hose and install them.
25. Connect one AN-08 90-Degree Male ORB hose end to the rear of each fuel rail. Plan a route for each
of the two lines between the fuel pressure regulator and the fuel rails, measure the two lengths of fuel
line needed. See section titled Hose and Fitting Assembly for fuel line assembly instructions. Once
the hoses are assembled, ensure there is no debris in the hose and install them.
26. Inspect the o-rings on the OEM quick disconnect fitting and replace if necessary. Coat o-rings and
the adapter fitting with a light oil and install the AN-06 / Ford quick disconnect adapter fitting on the
OEM By-pass fuel line.
Please note if installing a high performance fuel pump, (Similar to Aeromotive P/N 11101) the
OEM return line will be too restrictive to handle the volume of fuel that these pumps are
capable of pumping. To prevent loosing lower pressure adjustability of your regulator it will
be necessary to replace the OEM return line with a 3/8” ID (AN-06) return line in these cases.
