FUEL PUMP (H.O., S.H.O. and Cobra Systems Only) cont'd.

mounts, adel clamps and fasteners.

is completed at the Vortech factory for most models.

K. Place the 90° fuel connector (removed from stock line) into

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

L. Connect the 90° end to the inlet side of the fuel filter. Use

cable ties to keep lines up against underbody.

M. Mark and drill a 1/8" hole and mount relay inside trunk in

position as shown in template.

N. From relay terminal #85, tap the yellow wire into the stock

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

purple wire with a scotch lock. (On some model years, wire

may be brownish-green.)

O. Connect the short red wire to the (+) terminal at the fuel pump

relay terminal #87.

P. Connect the longer black wire from the (-) terminal at the fuel

pump to a clean ground.

Q. Connect the short black wire to the ground from relay terminal

box with supplied fuse tap and inline fuse. (The fused side

of the cigarette lighter is the preferred location.)

S. Check over the job and make sure everything is secure and

away from all moving parts and 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.
