I need to find the rubber fitting that connects to the plenum and then to both a hose to the control input of the decel valve and a hose to the auxilliary air regulator. Anyone know the part number for this and where to get one?

i come up with a "stacked vacuum elbow" 022.129.637B. i'm sure the PP price is wrong. AA price is $30.

part number 37?

Thanks much. The picture in my PET doesn't show this.

I made one for our 1974 2L car out of some fittings I bought at NAPA and they cost about $5.50 if I remember corectly, but of course it is not stock now if that is a big issue.

The question of availability of that part was brought up at the WCC this last spring. I believe someone found the same part available from/thru VW sources.

I fixed mine with a semi-thick coat of JB Weld around the rubber elbow. I don't think I'll ever have to worry about it again.
