T-REX® FUEL PUMP INSTALLATION (P/N 8F201-265)
NOTE: Make sure that the fuel level is below
1/4 tank for easier installation.
A. Remove spare tire, etc. from trunk.
B. Trim "Cut-Out" from template and place over spare tire hold-
down. Centerpunch and drill holes 3/16" diameter.
C. Jack up the rear of the car and support with jack stands.
D. Drop down the fuel tank by loosening the filler neck and the
two tank mounting straps. (There is no need to disconnect
any of the wiring or to completely remove the tank.)
E. Disconnect and remove the original rubber fuel line running
from the tank to the fuel filter . Remove the 90° plastic fitting
from the feed hose and set aside.
F. Attach one end of the supplied fuel line with connections to
the fuel tank pickup (see below). Route the hose around to
the front of the tank in the factory manner.
G. Place the Vortech supplied fuel adapter fitting, located in
the T-Rex pump inlet hose, into the new feed line coming
from the tank. Make sure that the white plastic retainer clip
is in place.
H. Reinstall the fuel tank and filler tube. Take care to route the
fuel lines and vent lines away from exhaust pipes and
provide room so that lines are not crushed between the
floor pan and the tank.

the end of the 5/16" outlet hose from the pump.

fuel harness in trunk near the right tail light. Tie into red/

and away from all moving parts or exhaust pipes. Make
sure no wires will rub on sharp edges. After you have
activated the pump, check for any leaks and correct if
necessary.
