The main function of the gasoline filter is to filter out impurities in the gasoline. The filter element consists of porous ceramic and paper, among which the paper filter element is made of resin-treated microporous filter paper, which has high filtration efficiency, low cost and easier maintenance.

Types of gasoline filters
Gasoline filter, the main sea spiral filter paper gasoline filter, line filter paper gasoline filter 2 kinds.
Line filter paper Gasoline filter: Gasoline filter in this type of filter, folded filter paper connected to the plastic, or metal filter at both ends, dirty oil into the filter, by the outer wall of the filter paper filtration, and finally reach the center of the discharge of clean oil.

Unlike the line type gasoline filter, the filter paper of the sea spiral filter is wrapped around the center tube. After the dirty oil enters, it is filtered out directly by the filter paper and the impurities are retained in the groove of the filter paper. This gasoline filter has better performance and is used in middle and high-end cars.

Cleaning principle of gasoline filter
The function of gasoline filter is to filter out water and impurities in gasoline. When the engine is operating, the fuel enters the filter settling cup through the inlet tubing, and the light impurities flow with the fuel to the filter cartridge. At this time, the clean fuel penetrates into the filter cartridge from the filter microhole and flows out through the tubing.

Gasoline filter replacement cycle
In general, combined with the driving road conditions, the gasoline filter needs to be replaced every 20,000 kilometers of the car.
Under normal circumstances, every 5000-8000 kilometers, we need to maintain the oil filter, gasoline filter, air filter.
