Performance characteristics of fuel filter
If the filter is installed in the fuel line, it is called the external filter (External); on the contrary, the internal filter (Internal) refers to the filter installed inside the fuel pump and the fuel tank. The fuel tank filter or its protective sleeve is generally considered to be a maintenance-free part.
Many imported car fuel filters use a drum connection (BanjoFITtings). In order to ensure the reliability of the connection seal, the same seal must not be used repeatedly. In addition, even if a new seal is used, the tightness of the connection must be checked after tightening. When the fuel system needs to replace the "O" ring, you must ensure that the "O" ring specifications and models are accurate, and check whether the elasticity and hardness of the ring are appropriate.
The fuel system without a circuit has only one internal filter (in the fuel tank). Although this all-in-one pump, filter, and delivery unit are expensive, when the fuel delivery is blocked or When the performance of the engine degrades as a result, proper maintenance and repairs must be carried out in time. At the same time, it is also necessary to check all fuel lines for faults and cracks and curling at the hose clamps.
