Had some richness problems and located a vacuum line that was flopping around in the breeze. Seems that the check valve had rotted to pieces and needs replaced.

Found the check valve (433-862-117-M93, an Audi part that is identical to 928-537-361-02, I guess?), but can't find the part number of the four way connector that connects the check valve and the banjo fitting on the manifold that (picture attached). Any help?

Most people just take all of the old lines out and start new.

I dont think there is a source for that 4 way.

Try Suncoast parts - I remember getting one of those from them in the past. You could also connect two 3-ways together to get a 4-way.

easier to go down to MB dealer for the 4 way vacuum fitting.Most of the parts guys call them chromosomes.They come in X and Y.Tell them you need an X.
