I have all the engine vacuum lines hooked up but I have one left (purple/blue/white) that is supposed to go from the left switchover valve which is midway on the left side of the engine bay and runs around the front of the motor to the air shut off valve. My problem is I can't find the air shut-off valve (item number 40 in the vac diagram). I know the US pollution control stuff is probably different on mine vs the US manual, but clearly the line is meant to attach somewhere. It's so long since I took it off I don't remember. I didn't write it down and I removed very few lines so it has to be obvious. I have removed the two water tanks and the alternator to see if I can locate it but still can't see it. Maybe someone with a RHD 380SL can peek in their motor for me?....... please please pretty please

I may have to go to post timing chain therapy class.

Thanks for the suggestion but I don't have the Haynes manual.

I'll have a look... got one

If you took a pic of your engine and drew a diagram of what you have currently installed... would help a lot.

Graeme, your shut-off valve looks like the photo below. It's located near the back of your air pump.

Hope this helps.

Air shutoff valve

Thanks Foto, I gotta run and look!

Success! I looked around that with my mirror but couldn't get the right angle to see the nipple. When I felt around it I could feel the rubber "U"- talk about hard to get at!

Thanks Foto and others- I can now be released from the asylum on day leave.

I put the pic in the CLAP thread to assist other inmates.

Follow up on air shut off vac line.

I must have pulled the line off while originally removing the generator as it goes under the generator and above the air pump. You can't see the nipple unless the air pump is extended (as when the belt is on), when it's not extended (ie loosened with the belt off) the nipple is hidden from view. Needed the surgical pliers again to attach the line to the nipple. I think it would be easier from underneath with the alternator on.
