Description

Tillotson Main Metering Diaphragm operates to open the fuel inlet needle valve which allows fuel to flow to the high and low fuel circuits.

You may hear us describing this diaphragm as the one that has the metal "wagon wheel" in the middle. The "wagon wheel" stabilizes the diaphragm and helps to control its movement so the dimple in the center is right above the tip of the fulcrum arm.
