and clips securing the injectors to the fuel rail.
8. FUEL INJECTOR REPLACEMENT, (1999-2000 models only)
A. The EGR tube must be modified to allow proper
clearance for the air inlet ducting. Using a tubing
cutter, cut the EGR tube just before the 90
°
bend
downward and just after the 90
°
bend that heads
to the exhaust manifold. Use the supplied flexible
tube to gauge the proper amount of tubing to be
removed, cut and discard section. (See
Fig. 9-a. )

Install the two 1/2" NPT x 5/8 tubing connectors
on to each end of the flexible tube and tighten.
(See
Fig. 9-b. )
C. Slide one end of the flexible tube assembly over
each end of the EGR tube and tighten the
compression fittings. (See
Fig. 9-c. )

D. Remove the four fuel rail screws (two per side).
Lift the fuel rails up and remove the injectors.
E. Lube the O-rings on the new injectors and install
into the fuel rails first, then install the fuel rail
assembly into the manifold. Reinstall the retainer
clips onto the injectors and fuel rail.
F. Reinstall the four fuel rail retainer screws. Install
the supplied jumpers onto the new injectors and
connect the wiring harness to each one.
G. Reinstall the previously removed components in
reverse order.
NOTE: New injectors have two grooves. Use the
upper groove which is closest to the
O-ring.
