燃油滤清器 2214701790 适合奔驰宝马丰田 汽油滤芯泵一体设计。

When a vehicle shows acceleration weakness, starting difficulties, rough idle, or a sudden stall while driving, this generally indicates a clogged or aging fuel filter, reducing filtration efficiency and failing to provide clean fuel to the engine. This part filters impurities and water from fuel and uses an integrated fuel pump to maintain constant fuel pressure to the injectors, ensuring complete combustion and smooth power. OEM number 2214701790; fits Mercedes-Benz, BMW, Toyota and other models. Installation requires releasing fuel system pressure before removing the old part; replace sealing rings and ensure the pump assembly seats fully in the fuel tank to prevent leaks or noise.
