Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a protective fuel filter. Background Art

[0002] The fuel filter is connected in series on the pipeline between the fuel pump and the throttle body oil inlet. The function of the fuel filter is to remove solid impurities such as iron oxide and dust contained in the fuel to prevent the fuel system from being blocked (especially the fuel injector). It reduces mechanical wear, ensures stable operation of the engine, and improves reliability.

[0003] For example, a fuel filter with the authorization announcement number "CN206668440U" realizes a reliable seal between the outer shell and the water cup, ensuring the normal use of the filter. At the same time, the first sealing element is easy to replace and maintain. However, the fuel filter is installed by means of threads, but when the operator tightens the threads, the threads cannot be aligned before tightening, which causes the fuel filter to fall off during operation, which reduces the working quality of the fuel filter. At the same time, the fuel filter fixes the water cup with a spring, but the spring will vibrate, which causes the water cup to fall off, which also reduces the working quality of the fuel filter.
