79 450SL accumulator and attached bits Qs

I rarely post on forums since my stuff is all kinda old, and others have solved the problems I face and the internet is good. But I'm trying to track down everything I need to replace the whole accumulator / fuel pump / filter cluster including all lines. I have found everything but the one (?) line coming from the damper. I found this lovely diagram here but not the associated part names.

I need 170 and 218 and their assorted bits. 218 looks like one t shaped line?

Thanks in advance and for so much info I rarely need to bug you at all.

I think 170 is a compensating valve and 218 is a leak off line. Don't shoot me if I'm wrong!
According to the manual I have it was modified in Feb 1979.

Wow thanks

SO this hose is available, just somehow separated from the 450sl parts connected to the fuel pump cluster.

Also thanks to an internal search ECS tuning has both parts here's the valve

So thankful for all the help

For posterity:

As usual Pelican Parts is too high. This forum sponsor (MB Dealer) is less. https://www.mboemparts.com/oem-parts...IFJlc3VsdHM%3D

Go to the supporting vendor forum. I think they have a code for shipping. Also try the valve number there.
