Looking for a Source for 11/32 Vacuum Hose - PeachParts Mercedes-Benz Forum

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

The original is a plastic tube.
I used 3/8" (9.5mm) Power Steering Return Hose on mine; made by Thermoid. No Clamps needed.

I replaced the original Plastic tube because I want to route the Hose more over the Fender Well and because the Hose is more flexiable I am less likely to break the Plastic Nipples off.

Got a trucker's parts house near you? That plastic hose matches a lot of the air lines for the braking systems on trucks. You may have to bring a piece an and let them match it, as they have it on rolls. If you can't find a truck parts place near you, truck stops with lube shops also carry it by the roll.
