Replacement diaphragm for the pump jet pump on the Dellorto DHLA series 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 22.1 mm in diameter with an extra brass collar around the cam of 12.9 mm.

The solid brass cam stands some 11.25 mm tall, measured from the collar, or some 12.5 mm measured from the disk.

This version was commonly used on Lotus turbo engines.

Required quantity per carburettor: 1

This is item number 76 in the drawing.

This is an authentic Dellorto diaphragm, produced at the Dellorto factory in Italy, using two layers of tissue provided by Effbe.

This is Dellorto Part Number: 10742
