step E. Install the fuel pump assembly
onto the vehicle through the license
plate opening. Use the supplied 10-
32 hardware to mount the pump
assembly to the existing hole in the
aluminum rear section. See photo.
E. Remove the 6mm bolt that holds the spare tire bracket in
position (threads from the front). Install the fuel pump
assembly onto the vehicle through the license plate opening.
Use the spare tire bracket hole and supplied 6mm x 25mm
bolt to line up the left side fuel pump bracket hole. Use the
corresponding hole in the fuel tank seam to mount the right
side pump bracket. Use the supplied 6mm screw, nylon
locking nuts and washers to secure (see photo).
F. Disconnect the factory fuel supply hose and connect the
new hoses as shown in the graphic on the next page. Use
the supplied tie wraps to keep the fuel lines away from sharp
objects. Make sure the lines are routed in such a way that
they make gradual turns with no sharp kinks or bends.
G. Wire the negative terminal on the pump and the #86 relay
terminal to a clean ground, free from rust and paint.
H. Using the yellow wire from the #85 relay and a wire tap,
splice into the grey wire in the factory fuel pump harness.
I.
Connect the #87 red wire on the relay to the positive terminal
on the T-Rex
®
fuel pump.
J. Run the remaining long red wire up to the battery, using tie
wraps to keep the wire away from heat and moving parts.
Using a solderless connector, connect the supplied fuse
holder and fuse to the end of the wire. Using the large ring
terminal, crimp both the ignition/boost control fuse wire and
the fuel pump fuse wire together (in the same terminal).
Connect the ring terminal to the (+) positive battery post.
K. Replace the license plate and frame, gas door, fuel overflow
catch and gas cap.
L. Refer to the graphic on the next page to confirm that all wires
are routed correctly. Replace the spare tire and cover,
making sure that the wires and relay are not contact with the
spare tire and mounting fasteners.
