6. FUEL INjECTOR REPLACEMENT (1999-2004 MODELS ONLY)

Disconnect the eight (8) fuel injector wiring

clips and retainers from the fuel injectors.

Release any residual fuel pressure from the

rail by opening the schrader valve on the

rail. Have a fire extinguisher nearby and use

extreme caution.

Remove the bolts holding down the factory

fuel rail onto the intake manifold. Lift up on

to the rails evenly, removing all eight

injectors.

Using a small amount of clean motor oil,

lightly lubricate the O-rings on both ends

on the Vortech supplied fuel injectors.

Install the new injectors into the fuel rails

with the terminals facing outward.

Carefully lower the fuel rail/injector

assembly down onto the intake manifold.

Check to see that each injector has been

seated properly into the manifold.

Tighten down the fuel rail assembly with

the original bolts and attach the wiring clips

to the injector terminals.

NOTE: Make sure injector retainers are

secure and properly installed.

Recheck after cycling fuel system.
