F 350 4WD Pickup V8-7.3L DSL (1988)
On trucks equipped with 7.5L EFI engines, wrap and fasten the insulator jackets (from kit) around the front brake tubes in the areas shown in Figure 3.
Be sure the insulators are assembled with the opening facing away from the exhaust manifold whenever possible.
NOTE:
Use all four (4) insulators on trucks built before approximately December 1, 1989. On trucks built after approximately December 1, 1989, the tee
block was deleted and lines 1 and 3 rerouted. Therefore, only brake tubes 2 and 4 will require the insulators.
