9. EGR CONTROL MOUNTING AND MAIN MOUNTING PLATE SUPPORT
(4.6L models only)
A. Using the #10-24 x 1/2” bolts, nuts and washers, re-
mount the EGR controls onto the Vortech mounting
bracket.
B. Directly beneath the EGR bracket, locate the 6mm
bolt securing the fuel rail. Remove the bolt.
C. Install the supplied support strap between the intake
manifold and the main mounting plate. Secure both
ends using the factory 6mm fuel rail bolt and the sup-
plied 3/8-16 x 1" hexhead bolt, nut and washer. Make
sure that the strap is not sandwiched in between the
fuel rail and the manifold. The support must be at-
tached underneath the bolt, and on top of the rail tab.
Improper assembly may cause fuel leakage.
D. With the two factory 6mm bolts previously used to
mount the EGR controls, remount the new EGR as-
sembly in the original location on the intake manifold
and secure. Reconnect all factory hoses and connec-
tors.
