There is a black (vacuum?) line that connects from the front of the motor and connects to a large round object (driver’s side) on the firewall right around the brake fluid reservoir. The hose/line is maybe 3/8 or 1/2 inch in diameter, and about 30-inches long. Halfway down the hose/line, it is split in half and there is an small plastic inline filter or maybe a valve?

Does anyone know what that inline valve/filter is called? And what it does? I broke off one side of it yesterday and I need to order a new one

Thanks

Anyone know were I could purchase this hose/filter? Autohauz doen't carry it, and I'm 50 miles from the nearest benz Dealership.

Thanks

You could get a generic check valve from the parts store (Autozone) and connect with vaccum line - I did on one of mine - at least until you get to the dealer.
