F. Check Vacuum Hose Harness Installation

1. Verify the presence of a vacuum harness between the EGR valve and the. carburetor as shown in Figure 13. If the vacuum harness is missing, skip to Section G.

2. Confirm that the vacuum delay valve of the harness is connected to the EGR valve and that the other port of the 3-way vacuum connector is connected to the thermovalve (Figure 14).

3. Verify that the vacuum harness is routed around the carburetor and the F-connector of the harness is teed into the vacuum hose connecting the base of the carburetor and the secondary throttle control diaphragm (Figure 15).

4. Ensure that the harness is tie-wrapped to the carburetor water hose to prevent interference with the carburetor linkage.

5. Continue with Section H.
