Replacing Vacuum Hoses (W124)

I'm hoping to do a massive swap-out of all my vacuum hoses over the holidays on my '89 124.

The local Merc parts mgr, who is an old car buff, suggested replacing all of my vacuum tubing with Marine reinforced rubber tubing, as he said it's what he does with all of his classic cars, and it's much more robust.

I'd like to know :

1. If anyone else here has done this?

2. If you have, do you recommend it? What was your experience?

3. What specific marine tubing would should I purchase. Type? Size? (and length required to replace all existing enginer compartment tubing?)

FYI, I was just looking at something like the following:
SHIELDS RUBBER Series 368 Low-Permeation Marine Fuel Hose | West Marine

All comments welcome.

Thanks in advance

Thumbs up

I just use 1/8" silicone for my vacuum tubing.

Be mindful of that splitter behind the booster, it feeds to vac/econ gauge, HVAC, and the vac reservoir I believe. I had to order it from MB, also the plug to the inlet of the vac res too.

I'm planning of doing the same thing in the next weeks, by any change did he gave you a list of all the connectors and spitters to replace?

I always use silicon vacuum lines, used them in two turbo cars and they stayed good for years.

Good luck, I've been searching and asked vendors but nobody could give me a solid answer.

I've emailed local Merc Dealershp parts guy. He's usually pretty good. I'll see what kind of schematic/parts info he can make available, and post here if appropriate.
