Remove the spare tire. 2. Remove the EVAP canister mounting bolt (see Figure 1). • The canister will drop about 3 inches which will give you working room at the top. 3. Disconnect the vent hose (see Figure 1). 4. Reach above the EVAP canister and disconnect the vent hose at the vent control valve and remove the hose (see Figure 2). • Twisting the hose at the opposite end will help loosen it at the vent control valve. 5. Cut out the template on page 9 and place it on the frame rail as shown in Figure 3. • Make sure the template is aligned (straight) with the frame rail. 6. Center punch and drill a 13/32 (10 mm) hole at the location shown. Existing hole in frame 7. Prep the hole you just drilled as follows: a. Remove burs from the edge with a file or sandpaper. b. Clean the hole with solvent and allow to completely dry. c. Apply / cover all bare metal with Zinc Rich primer (see Parts Information for Zinc Rich primer). d. Alloy primer to dry—approximately 1 hour. 8. Prepare bracket for installation as follows: a. Assemble the collapsible nut, spacer nut, and bolt as shown.
