This fuel filter is very effective at keeping dirt out of the carburetor, but it is small enough that it can clog easily. A spare filter is cheap insurance! Installs under the brass plug on the underside of the top plate. The closed end should be inserted into the plug, and the open end should go into the top plate.
Fits Weber DFV series, DGV series, DCOE series, and 48 IDA (dual) carburetors. Not for IDF series or 40 IDA (triple).
