Mini-tube vacuum hoses are used in the vacuum hose harness (19C827)
.
They provide greater flexibility with less tendency to collapse and are
less susceptible to pinching.
Service is easily performed using a short piece of standard 3mm
(1/8-inch) ID vacuum hose and inserting the cut ends of the mini-tube into the
ends of the standard 3mm (1/8-inch) ID vacuum hose.
