5.2 FUEL PUMP INSTALLATION (1998 MODELS ONLY)
A.
Remove the spare tire, etc. from the trunk.
B.
Jack up the rear of the car and support with
jack stands.
C.
Mount the fuel pump to the underside of the
spare tire well with the adel clamp and #8
fasteners provided. (See Figs. 5.2-a, 5.2-b.)
D.
Remove the factory female hose end
connected to the fuel filter inlet.
E.
Insert the supplied 1/2" fuel pump inlet hose
adapter fitting into the factory female supply
hose fitting by gently pushing the fittings
together and making sure they are locked.
F.
Attach the supplied 1/2" fuel hose to the
pump inlet and the inlet hose adapter fitting.
Use the supplied #4 clamps to secure both
ends. Cut hose length, if necessary.
G.
Fasten the extended pump inlet line clear of
the filter 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
pump discharge line onto the fuel filter inlet
making sure the hose assembly clears all
exhaust tubing and sharp objects.
I.
Mark and drill a 1/8" hole and mount the relay
inside the trunk in position as shown in the
template. Use the sheet metal screw
provided.
J.
From relay terminal #85, tap the yellow wire
into 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, the wire may be brownish-
green.)
K.
Connect the short red wire on relay terminal
#8 to the (+) terminal on the fuel pump.
L.
Connect the longer black wire from the (-)
terminal on the fuel pump to a clean ground.
M.
Connect the short black wire to a clean
ground from relay terminal #86 (relay screw
mount works well).
N.
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.

pipes and sharp edges on the
vehicle underbody.
