I’m searching for a vacuum leakage and found an open connection in the engine bay: See picture; #1 and #3 are connected, but not #2.
Should also the third tube be connected?

My car is a 1995 C2. It has the same device, but #2 and #3 are connected to vacuum tubes, while #1 has only the U-shaped rubber piece. I think one of the ports on this device is a vent, and the U-shaped piece is to keep water/debris out.

The set up on my 95 C2 is identical to that of BobbyT.

I knew our cars were old-school, but VACUUM TUBES?

Ha! I thought the same! (Nice looking amps, Bruce. I'll have to sample one day when I'm in the Bay area...)

OP, there is a ~8" long small black tube (like the rest of the vacuum lines) that goes directly towards the front of the car up under the heater blower/fan assembly. It hits a T-junction under the blower (might be a 4 way connector). If you can see under the blower, you'll probably spot it.

If not, pull off the blower (fun the first time finding those 2 bolts on the side....10 or 11mm and use a short extension (or deep socket) to make it easier to get at them. There is 1 electrical connector on the driver's side as well. Re-install of the blower is also "fun" the first time...).

Great, thanks!
I had switched #1/#2 wrongly in the search for vacuum leakage. Now there is no more leakage!
Regarding vacuum tubes, also available in amps, suppose my wording wasn’t the best. Anyway, good point, Bruce.

Thanks! I'll be at the LA Amp Show (www.ampshow.com) in October!
