Fuel filter performance characteristics
If the filter is installed in the fuel line, it is called the external filter (External); otherwise, the internal filter (Internal) refers to the filter installed inside the fuel pump and the fuel tank. Of these, the fuel tank filter or its protective cover is generally considered a maintenance-free component.
Many imported cars have fuel filters with drum tube connections (BanjoFITtings). In order to ensure the reliability of the connection and sealing, the same gasket must not be used repeatedly. In addition, even if a new gasket is used, the tightness of the connection must be checked. When the fuel system needs to replace the “O” ring, it is necessary to ensure that the “O” ring has the correct specification and model, and check whether the elasticity and hardness of the ring are appropriate.
The non-circuit fuel system has only one internal filter (in the fuel tank), although the all-in-one pump, filter, and delivery unit are expensive, but when the fuel delivery is blocked or When the performance of the engine is thus degraded, it must also be properly maintained and maintained in a timely manner. Also check for faults in all fuel lines and for cracks and crimps at hose clamps.
