DD, Do you remember where you sourced the metric vacuum hoses? How many different sizes did you need? Did any have pre-formed factory bends, and if so, did you buy OEM, or just bend the generic hose to make it work?

 

Unfortunately I did this like 8 years ago. I just went to O'Reilleys and bought a couple of feet of vacuum hose for about $3

At the time, the car was still a "project" and I didn't want to put a lot of money into it until I knew I could fix the roof and other stuff it needed.

The reason I said Metric vacuum hose is because the stuff at oreilley's fit, but did not fit snug.

Today I might go with the OEM hose for some of the more complex bends. But I think I recall it was like $35 for just one hose.

It turns out that if you google metric vacuum hose on amazon, you end up with normal hose sizes converted to MM's. I dunno if that is a scam or if there is just universal hose sizes

I think the hose was all the same size. And I think I had to go back for more, since one of the runs goes from the left side of the engine to the right side of he engine.

So maybe you want to start off with 2 meters worth of hose

 

check and replace the evap hoses. easy to do and cheap way to start. good luck
