Replacement diaphragm for the pump jet pump on the Dellorto DHLA series carburetors.

Replacing the diaphragm is then the only sensible option.

The solid brass cam stands some 12.8 mm tall, measured from that metal disc.

The rubberized textile material is undulated as visible in the photograph.

Required quantity per carburettor: 1
