Vacuum Harness Assembly - Nylon

Engine vacuum systems are currently installed as a pre-assembled color coded type of harness. The colorings act as a visual aid both during production and during service.
The emission decal on the engine provides a color coded vacuum routing schematic, which corresponds with the pre-assembled harness.

Nylon Vacuum Harness Tubing And Connectors:

The vacuum hose harness consist of colored nylon tubing (0.15" o.d. and 0.09" i.d.) bonded to nylon or rubber connectors.
A rubber insert is installed in the end of the nylon connectors to provide a secure fitting seal at the components nipple connection.
Occasionally, rubber hosing (5/32" or 7/32") may used within the harness to replace a damaged nylon vacuum tube.
