carburetor diaphragm

(0)

Diaphragm for all BING carburettors with a throat diameter of 32 mm and 26 mm (inner through-hole of the carburettor).

The throat (through-hole) is measured inside the carburettor.

The diaphragm is made of suitably soft petrol-resistant rubber.

The diaphragm works well over the entire engine speed range - it successfully replaces the expensive BMW 13111254774 original diaphragm.

For a BING carburettor with a throat diameter of 40 mm, select diaphragm 13-11322.
