sending unit with a larger fuel line. Vehicles originally
equipped with small block engines typically have 5/16"
lines while big block engines have a 3/8" fuel line. If your
model car was available with both small and big block
engines there should be a 3/8" sending unit available.
Note that some of these sending units have both an outlet
and a return fuel line provision.
If you cannot source a sending unit with a 3/8" fuel
line you will need to have one custom installed in your
tank. This should be accomplished by an experienced
professional who can modify your fuel tank.
Since the line from the tank to the pump is low pres-
sure you can secure the -08 hose to the tank with a sup-
plied hose clamp. The rest of the connections are made
with the supplied push lock hose ends.
Mounting and Plumbing the Fuel Pump and Pre-Filter
Select a location for mounting the pump. Be sure to pro-
vide enough space between the tank and the pump to
allow for the pre-filter. The pump and filter should be
mounted as low as the lowest portion of the fuel tank.
They should also be mounted within three feet of the
tank. This is important to avoid premature pump failure.
This kit includes a billet mounting bracket for the
pump. Using the bracket as a template, mark two mount-
ing holes on the frame (if that's where the pump will be
mounted) and drill 4 MM holes for #10 self tapping metal
screws. Mount the bracket to the frame with the sup-
plied#10 self tapping metal screws.
Note that the pump is directional and must be posi-
tioned with the wire terminals facing the front of the ve-
hicle. Slip the pump into the bracket and clamp it
securely. See Figure 5.
Find a suitable location for the filter positioned be-
tween the tank and the pump. Mount the filter to the

frame using the supplied Adel clamp. Again, drill a 4MM
hole and use a #10 self tapping screw to hold the clamp.
Measure out the necessary lengths of the -08 hose to
run from tank to the filter and from the filter to the pump.
Cut the hose cleanly using a sharp blade. Make sure the
ends are cut square. Install the push lock hose ends by
securing the hose end in a vise, making sure you provide
some protection to avoid damaging the hose end. Do not
clamp too tightly. Push the hose onto the hose end mak-
ing sure it is seated all the way. It will ease installation by
using some WD-40 or similar lubricant.
Connect the hose from the tank to the filter and a sec-
ond hose from the filter to the pump.
Plumbing from the Pump to the EFI
The next step is to determine the lengths of the -06 hose
which will run from the pump to the post-filter and then
a second hose from the filter to the inlet port of the FiTech
EFI system throttle body.
Note that the post-filter can be located anywhere be-
tween the pump and the throttle body. This filter is very
light and can be supported by the fuel hose. No mounting
clamp is required but you will need to provide some type
of support for the fuel line at several points between the
pump and the engine compartment. It can be tie-wrapped
or held in place with small Adel clamps. (Not supplied)
The FiTech EFI Throttle Body has three inlet ports and
one outlet port. The outlet port is marked "Return." Select
one of the three inlet ports and install a supplied -06 AN
inlet fitting. The return port requires a special fitting
which is already installed in the throttle body. Install the
supplied plugs in the two unused ports. You will have one
plug left over. This is required when using the Fuel Com-
mand Center which is returnless and the return port is
also plugged. See Figure 6.
Connect the -06 fuel hose from the filter to the inlet fit-
ting on the throttle body.
Wiring the Fuel Pump
The FiTech ECU mounted on the throttle body has a small
sub harness that is connected to it. In this sub harness
is a large orange wire. Extend that wire and connect it to
the positive (+) terminal on the fuel pump. Connect one
end of a ground wire to the (-) terminal of the fuel pump
and attach the other end to one of the screws holding the
pump to the frame. Make sure the wire makes contact
with bare metal.
Where is the Fuel Pressure Regulator?
You may wonder why no fuel pressure regulator is used.
That's because the FiTech System throttle body contains
an internal fuel pressure regulator that maintains fuel
pressure into the system at a constant 58 PSI.
