There are three types of fuel filters (Diesel filter), gasoline filter (Fuel Filter) and natural gas filter (Gas filter). The function of the fuel filter is to prevent particles, water and impurities in the fuel, and to ensure that the precision parts of the fuel system are protected from wear and other damage.
China's filter has gone through more than 30 years, starting from Bengbu, which initiated the establishment of national testing standards in Bengbu in the 1980s, which promoted the rapid rise of the entire industry, especially the Wenzhou model, which shines brilliantly, from car accessories to auto parts, from car exteriors to There is a qualitative leap in the interior, but the fuel filter, that is, the gasoline filter, has not been paid attention to. It is the product with the least replacement frequency among the 4 filters and the most easily overlooked product. The gasoline filter has been latent for many years. The acceleration of speed, the rapid rise of oil prices, the change of the environment, the technology of environmental protection, the reduction of carbon emissions, the change of gasoline filters from external to built-in, and the change from carburetor to EFI, built-in gasoline filters have become a trend.
If the filter is installed in the fuel pipeline, it is called an external filter (External); otherwise, the internal filter (Internal) refers to the filter installed inside the fuel pump and fuel tank. Among them, the fuel tank filter or its protective cover is generally considered to be a maintenance-free component.
The fuel filter of many imported cars uses a drum tube connection (BanjoFITtings). In order to ensure the reliability of the connection seal, the same gasket must not be used repeatedly. In addition, even if a brand new gasket is used, the tightness of the connection must be inspected. When the fuel system needs to replace the "O" ring, it is necessary to ensure that the specification and model of the "O" ring is correct, and check whether the elasticity and hardness of the ring are appropriate.
The fuel system without circuit has only one internal filter (in the fuel tank), although this all-in-one (all-in-one) pump, filter, delivery unit is expensive, but when the fuel delivery is blocked or When the performance of the engine is reduced due to this, it is also necessary to carry out proper maintenance and maintenance in a timely manner. Also check for faults in all fuel lines and for cracks and crimping at hose clamps.
