As the car energy source, there’ll be some impurity and water in the gas producing, delivering and filling procedure. The impurity will be sent to the fuel system and engine cylinder, it will cause the cylinder friction, oilway blockage, dam age injection nozzle.  The fuel filter eliminates ferric oxide and impurity in the fuel oil, to prevent the fuel system blockage(especially the injection nozzle). 
Reducing the machines friction, keep the engine stable operation.
