I've got a similar setup on my 420SEL that's shown as part of the evaporative controls. Sucks the fumes out of the intake after shutdown to prevent environmental pollution. See if it doesn't go to the evap cannister that collects the fumes and then returns them on startup.

Purge valve, connects inside the fender to the charcoal cannister, where another line will run to the rear of the vehicle connecting with the fuel tank.

Purpose: Allow vapors, not fuel, from the fuel tank to pass through the charcoal rather than vent to the atmosphere. During certain engine running criteria the cannister is "purged" of the collected vapors.

Thanks MrCjames,

Do you know what happens if it does not work?
I have idle problems when warm and engine stalls while running

I do not think this device would cause your stalling problem however, if you blocked off the vacuum side and the stalling ceased than one would have to assume that there may be a connection.

If you can give some more details regarding your stalling problem (hot/cold, pulling up to stop signs,.... yadi yadi yadi) I think you will find that you will get flooded with possibilities.
