‘67 Barracuda vacuum gauge connection

Bumping this up to ask if anyone knows of any places selling the original style thin wall vacuum tubing.
It looks similar to the original washer hose to the squirters but a size up.
The one in my car is OK but I've had to splice in the engine compartment.

Related to earlier posts, here's a photo of the routing behind the instrument panel.

The original hose, where it is not stretched, measures 0.21" O.D.

The vacuum gage fitting measures 0.159" O.D.

Vacuum hose is usually listed by nominal sizing, which according to some tables does not always have the same nominal size as the fitting.
So the fitting may be nominal 5/32, or 1/8 and the hose could be nominal 7/64.
But I really don't know.
The easiest would be if someone is selling the correct hose.
It needs to be thin wall to go through the grommet and to fllow the route behind the dash without getting pinched.
