1 x genuine weber emulsion tube to suit Weber Carburettors;

DCO, DCOE, IDF, 48 IDA & PMO triple barrel carburettors

More high holes typically means a leaner mixture under slight accelerations, more low holes is richer. The thickness of the emulsion tube also has an impact on the amount of fuel sitting in the well surrounding the emulsion tubes.

The Weber tuning manual has may pages dedicated to emulsion tubes with detailed drawings and measurements of the varying emulsion tubes.

** Please note**

This is a genuine Weber (European) emulsion tube - NOT a Chinese copy.

When purchasing Weber jets and venturi, you are purchasing precision calibrated parts. Make a habit of asking if they are genuine and where they are from. Give your weber carburettors the genuine parts they deserve.
