C. Fuel pump and fuel filter mounting/Feed hose
1. Insert the supplied fuel tank pickup unit and o-ring into fuel
pump opening in the top of the fuel tank and secure with the
factory retention ring (the fuel pickup is designed to be
installed without a strainer attached).
2. Slide the supplied 12” long piece of -10 “push-on” hose onto
the supplied -10 x 120
°
hose end. Attach the -10 x 120
°
hose
end with hose attached to the tank pickup. The fitting should
be flat and parallel to the tank and point toward the rear of the
vehicle. Tighten (until snug) the fitting to the pickup.
3. Attach one of the supplied -6 straight hose ends into the end
of the supplied length of -6 hose. Attach hose end to the -6
fitting on the tank pickup and tighten until snug. The hose must
be routed toward the front of the vehicle when the tank is re-
installed.
4. Reinstall the fuel tank and filler tube. While lifting the tank,
reconnect the tank vent hose and secure. Reconnect the fuel
level sending unit harness (if disconnected). Take care to
route the fuel lines and vent line away from exhaust pipes and
sharp edges. Provide room so that the lines are not crushed
between the floor pan and the tank.
5. Assemble the fuel filter and two -10 o-ring fittings as shown in
the fuel system schematic (Make sure that the 3/8” NPT x -10
fitting with o-ring is in the discharge end of the fuel filter. The
discharge end is the end that does not have the spring).
•
Assemble the two 1/4 NPT x -6 fittings into one of the
previously plugged Y-blocks (use a small amount of pipe
sealant on the threads of all pipe fittings). Thread the Y-block
assembly onto the 3/8” NPT x -10 fitting previously attached
to the fuel filter (see Photo 1).
•
Use the supplied 1/4” nuts, bolts, washers and clamps to
attach the supplied filter mounting bracket to the fuel filter as
shown in Photo 1.
•
Temporarily thread the supplied -10 x 90
°
hose end onto the
fuel filter inlet. Take the fuel filter/bracket/Y-block assembly
and place it up against the outside bottom of the floor pan of
the trunk (see Photo 2). Line up (left to right) the 90
°
filter inlet
fitting to the -10 hose coming from the tank pickup so that a
“straight shot” from the tank pickup hose is obtained with a
NOTE: When assembling blue “push-on” hose and
hose ends, use a light amount of oil to lubricate the
inside of the hose and hose end nipple to allow for
easier assembly. Push the hose onto the hose end
until the hose contacts the plastic stop on the hose
end. Pressure check the hose to twice the maximum
operating pressure. See the last page of this instruc-
tion sheet for “braided” hose/hose end assembly.

NOTE: Uncut bulk length hose has been supplied in
this kit to allow for minor variances in each installa-
tion. The fuel system schematic on page 6 shows the
intended layout of fittings, hose ends and general
hose lengths (study over diagram before proceed-
ing). Actual hose length may vary slightly due to
installer and/or vehicle setup. Use the lengths shown/
given as a guideline. Measure between the fittings
that are to be connected before cutting hose.
