I. Secure the fuel pump/line assembly to the
vehicle with the supplied rubber isolators,
nylock nuts, and hardware. (See
Figure
20-c .)
J. Reinstall rear carpet and seats.
K. Route the T-Rex inlet hose around the front
of the fuel filter to form a smooth, gradual
bend to the pump. Attach into the 3/8" barb
in the factory feed line. Secure the
connection with a #8 hose clamp. (See
Figure 20-a .)
L. Attach the factory snap connector removed
from the original line into the T-Rex
discharge line. Secure with supplied #8
clamp. Attach the line to the fuel filter inlet.
Use cable ties to keep all fuel lines tight up
against the underbody.
M. Using a 1/8" drill, make a mounting hole in
the frame crossmember above the T-Rex
pump to mount the relay wiring harness and
provide a grounding point. Remove all paint
and dirt from around the hole. Mount the
relay, fuel pump grounding wire and #86
relay terminal using the supplied sheet metal
screw.
N. Using the yellow wire from the #85 relay
terminal and a wire tap, splice into the grey
wire in the factory fuel pump harness. (See
Figure 20-b .)
O. Connect the #87 red wire on the relay to the
positive terminal on the T-Rex pump.
P. Run the remaining long red wire up to the
battery, using tie wraps to keep the wire
away from heat and moving parts. Connect
the supplied fuse, fuse holder and large ring
terminal to the wire and attach to the remote
(+) positive battery terminal.
Q. Replace the fuel tank filler cap.
20. T-REX FUEL PUMP INSTALLATION, cont'd.
NOTE: It is important that all fuel lines have
no contact with moving parts,
exhaust components or sharp
corners. Make sure lines are routed
with gentle bends and secured with
the supplied tie wraps.
IMPORTANT! Pressurize the fuel system to
check for any leakage before
starting the vehicle.
