I'm in the process of redoing the main vacuum line from the vacuum pump on an OM617.952 to the brake booster and would like to find the right replacement hose material. My ends and check valve are perfect, so it's just the hose I want to change out. One of the hoses I have has no markings on it, but another one has the following

DOT - TECALEMIT - 84 07 -11/32 -VL

The stock configuration really doesn't work because the distance from the vacuum pump connection to the brake booster is different and the routing is a little different as well (it's part of an engine swap project), so just sourcing a new one is not a real solution.

The hose is very hard, looks almost heat shrunk and has taken a set after years in the hot engine compartment. The material does not soften up under application of a heat gun.

Forum and web searches turn up essentially nothing.

Any ideas on a good source? ...or maybe an alternative product/material
