Good day all!
I'm owned by a 1976 450SL.

Every hard type vacuum line is original . Just a touch can break them.
is there a kit available to replace this plethera of vaccum spaghetti that permeates the engine bay of this automobile?

Is there an aftermarket kit using something nicer like high heat silicone tubing out there?

Examples of the things that need replacement

Max Blast

This is a pretty standard product that’s still available, you may also find it by looking at different manufacturers air suspension air lines.

LOL@intro. Don’t give that car your lunch money.

I saw on some car show where they were redoing an old MB wagon and he bought some vacuum line fitting kit and just a soebulk vacuum lines in various IDs.

Probablynot gonna find a kit unless you go to the MB classic part store thingy in California I have read about.

Change the hoses and fittings as both get brittle over time.

Amazon and other online stores have tons of stuff:
Tubing and Hose from Cole-Parmer (coleparmer.com)
WEB Catalog ｜SMC CORPORATION (smcworld.com)
