Here we have a replacement diaphragm for the elaborate "temperature controlled accelerator pump" as used on some versions of the Weber TLDE carburettors.

Weber equipped some examples of these carburettors with this system that is controlled by the temperature of the coolant.
On acceleration, it injects extra fuel into the primary venturi when the coolant temperature is below 25 degrees Celcius.

Starting from 25 degrees it gradually starts to close and should be fully closed when the coolant reaches 45 degrees.

These diaphragms now tend to suffer from age and the ravages of aggressive modern fuels which can cause them to harden and even crack, causing erratic running of the engine and fuel leaks.

Replacing the diaphragm is then the only sensible option.

Required quantity per carburettor: maximum 1

This diaphragm is Number 16 in the drawing.
