Tee'd into the NHS brake booster check valve with the 8mm ID vacuum hose fitting is an easy install and it gives the car a new brake booster check valve at the same time. They're plastic and don't last forever.

A piece of 5/16" or 8mm inside diameter fuel line around 4 feet long secured with hose clamps will comfortably reach from the special brake booster check valve to the back of a VDO/NHS mechanical boost gauge mounted where the clock goes in a 911 dashboard while you're holding it in your hand before pressing it into the rubber ring in the dashboard.
A little vasaline or silicone grease smeared on the rubber ring ID or OD of the boost gauge will let it slide into the dashboard easier.
