55493549 Fuel Metering Valve for Fuel Supply Pump used on Humber/GMC/Chevrolet Made by Henshine

 

The  Suction Control Valve   55493549   is generally installed at the inlet of the Fuel Injection Pump. It is a proportional solenoid valve, controlled by the electronic control unit (ECU), which can control the amount of oil entering the high-pressure fuel pump, thereby controlling the oil pressure in the common rail pipe. The good work of this component can not only ensure that the vehicle can run normally but also enable the engine to run in the most fuel-efficient state to achieve the effect of saving fuel.

                 A fuel pressure regulator also named a suction control valve, or SCV Valve helps maintain the fuel pressure in the Fuel                   
             Injection System.
                If the fuel injection system needs more fuel pressure, the fuel pressure regulator releases more fuel to go to the engine.
                This is vital because that is how the fuel gets to the injectors.  Blocking the pass-through to the fuel tank off completely,
                the fuel pump will try to force too much fuel into the injectors which will cause them to fail and you will end up needing
                another auto repair service.

                As you could see, the pressure regulator plays a critical role in the common rail diesel injection system.

                 A good factory, a good supplier with stable quality, and follows  IATF16949  rules strictly.  

               After being tested by many of our customers in Europe and the Americas, this pressure regulator is a good replacement
               for OE diesel parts, like  55493549  Diesel Metering Valve.
