(36) Pump Diaphragm for Dellorto PHBR carburetors 11345
Original Pump Diaphragm for Dellorto PHBR carburetors.
The original diaphragms now start to suffer from age and the ravages of aggressive modern fuels which causes the "rubberized textile" material to harden and even crack, causing erratic running of the engine and fuel leaks.
Replacing the diaphragm is then the only sensible option.
Please note that there are different versions available of this diaphragm, with the metal disk on this one measuring 19 mm in diameter.
The solid brass cam stands some 12.8 mm tall, measured from the face of the disk.
Required quantity per carburettor: 1
