Development of fuel filter  

Filter has been more than 30 years in China, from bengbu initiated the establishment of national testing standards in bengbu in the 80 s in order to impel the rapid rise of the industry, especially the wenzhou mode puts glorious greatly, from automotive trim to auto parts from external to internal car have a qualitative leap, but the fuel filter The fuel filter has not been seriously,  He is 4 in the filter in the frequency of the least, one of the most overlooked products, fuel filter Dormant for many years, with the car speed up, fast heating, oil prices environment transformation, skills, environmental protection, reduce carbon emissions, fuel filter from external to internal, from the carburetor to the change of the efi, built-in fuel filter has become a trend.  

Performance characteristics of fuel filter  

If the filter is installed in the fuel pipeline, it is called External filter;  Conversely, the Internal filter (Internal) refers to the filter installed in the fuel pump and fuel tank.  The fuel tank filter or its protective sleeve is generally considered as a maintenance-free component.  

Many imported vehicles use BanjoFITtings for fuel filters.  In order to ensure the reliability of the connection seal, do not repeatedly use the same gasket, in addition, even if the use of a new gasket, must also test the tightness of the connection after fastening.  When the fuel system needs to replace the "O" ring, it is necessary to ensure that the "O" ring specifications and models are accurate, and check whether the ring's elasticity and hardness are appropriate.  

A non-loop fuel system has only one internal filter (in the fuel tank), and while this all-in-one pump, filter, and transfer unit is expensive, it must be properly serviced when fuel delivery is blocked or engine performance deteriorates as a result.  Also check all fuel lines for faults and for cracks and crimping at hose clamps.
