This vacuum hose is the very small outside diameter hose that is in the engine compartment and runs inside under the dash. It is used on all z's with factory AC from 1974 to 1989. It is important to use the right size hose and keep it in good shape. If you split a hose on this circuit your heating and A/C systems will cease to function. On the 74-78 z's you'll only get air flow out the center vent in the dash if you lose vacuum to this system.

This listing is for a single foot of hose. We sell it by the foot in bulk form and you can buy as many feet as you like as long  as it's at least 15 feet. The 74-78  z's use about 30 feet under the hood and even more under the dash.
