I'm looking for a reference picture of the 1976 1/2 and above SVDA vacuum hose routing diagram. It's missing from my Bus and the only photos I can find online and in the Gallery reference a DVDA.
I need one with the SVDA and mechanical EGR valve. If you have one on your engine lid then please take a pic and post it here!

I'm looking for the official sticker, should be next to the emissions sticker on the engine lid. Ratwell only has DVDA vacuum hose layout as far as I can see.

I always assumed that green line was dashed because it wasn’t on every engine. At least that’s what I would say to the smog ref….

Oh maybe. Combined with the timing spec that should be pretty clear. It is missing the vacuum connector to the vacuum activated EGR valve so I still expect to see more than one sticker.
