Vacuum Harness Assembly - Nylon

Vacuum Connectors Used With 5/32 Inch Rubber Hose for Service:

Engine vacuum systems currently use a preassembled 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 preassembled 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).
