Vacuum Harness Assembly-Nylon

Engine vacuum Systems currently use a pre-assembled harness which features colored nylon vacuum lines. The color is a visual aid both in production and in service. The emission decal on the engine provides a colored schematic of the vacuum hook-up which corresponds with the pre-assembled harness.

Vacuum hose harnesses consist of nylon hoses . . . 0.150-inch outer diameter and 0.090-inch inner diameter bonded to nylon or rubber connectors. Occasionally, a rubber hose may be connected to the harness. The nylon connectors have rubber inserts to provide a seal between the nylon connector and the component connection (nipple).
