[W126 Coupe] [W126 coupe] Hissing sound behind the cluster

[Bruce Mendel]

it's probably the vacuum line that shows gas mileage. see if your gas mileage needle moves at the bottom of the cluster when you give the car more or less throttle. if it does not move, that's it. just remove cluster and pop the hose back on.
