PETROL FEED PUMP MEMBR. GUIOT

This fuel pump diaphragm is intended for use in classic Citroën engines of the 11CV, 15CV and HY series. The part provides the flexible sealing surface in the mechanical fuel pump and supports stable fuel delivery to the carburettor. The round shape with a diameter of 91 mm fits pumps with a matching housing. The diaphragm operates with the pump spring, body and actuating mechanism. The material resists petrol and helps maintain pressure and flow in the fuel system under different engine operating conditions. It forms a key wear component in the pump assembly and can be replaced during maintenance.
