D. Reinstall rear carpet and seats.
E. Loosen the tank filler cap to vent any residual
pressure.
F. Disconnect the original plastic fuel feed hose to
the fuel filter inlet.
G. Route the fuel pump inlet hose around the front
of the fuel filter to form a smooth, gradual bend to
the pump. Attach the hose to the factory supply
line from the tank.
H. Attach the pump discharge line to the inlet of the
fuel filter. Use wraps to keep all fuel lines tight
against the underbody. (See
Figs. 13-a, 13-c.)
I. Using a 1/8" drill, make a mounting hole in the
frame crossmember above the fuel 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.
J. 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
Fig. 13-d,
13-e).
K. Connect the #87 red wire on the relay to the
positive terminal on the fuel pump.
L. 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.
M. Replace the fuel tank filler cap.
13. FUEL PUMP INSTALLATION, cont'd.

IMPORTANT! Pressurize the fuel system to
check for any leakage before
starting the vehicle.
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.
