fuel filter inlet.
F. Insert the T-Rex inlet hose assembly into the
female supply hose fitting by gently pushing
the fittings together and making sure they are

by looping the two 11” cable ties through the
front slot on the fuel filter mount, being careful
not to kink the line.
H. Plug the female connector located on the T-Rex
discharge line onto the fuel filter inlet making sure
the hose assembly clears all exhaust tubing and
sharp objects.
I. Position the reflective sleeve on the pump dis-
charge line so that it receives maximum protection
from the tailpipe.

inside the trunk in position as shown in the tem-
plate. Use the sheet metal screw provided.

the stock fuel pump harness in the trunk near
the right tail light. Tap into the purple wire with
the supplied scotch lock. (On some model years,
wire may be brownish-green.)

to the (+) terminal on the fuel pump.
M. Connect the longer black wire from the (-) terminal
on the fuel pump to a clean ground.
N. Connect the short black wire to a clean ground
from relay terminal #86 (relay screw mount works
well).
O. Route the remaining long red wire from relay
terminal #30 up to the fuse panel located under
the dash. Using a solderless connector, connect
the supplied fuse holder and fuse to the end of
the wire. Crimp the fuse wire to the supplied
female slide and fuse tap. Attach fuse tap and
wire to fuse #17.
NOTE: Use extreme caution when routing fuel
lines. Make sure fuel lines are located
away from hot exhaust pipes and
sharp edges on vehicle underbody.
