The fuel fine filter of the fuel injection system is significantly different from the filters of other systems. Its task is not to let particles larger than 10 microns pass, otherwise the nozzles will not work. They work in a pressurized system, the nozzles must be protected from dirt. Therefore, the requirements for fuel filters must be increased. Replacing the filter is much easier, anyone can do it than cleaning nozzles, much less changing them. Filters for «dozen» larger in volume than carburetor ones, and are in a metal case. The filter is attached to the body on a special bracket that covers the filter. The filter is connected to the fuel system with threaded fittings.
The standard filter has an index of 212-1117010-03 or 02. They are produced by different factories. But it's better if you «friend» pick up an imported fuel filter, aviation and rocket ones are very good. They can purify gasoline and water. And you can attach any.
The fuel injection system also places high demands on the air filters. They should filter the air cleaner. Therefore, the filtering surface on these filters is larger. Their shape is rectangular. The upper and lower bases of the filter element, the so-called mating surface, are made of soft polyurethane, which allows better sealing of the joint between the filter element and the filter housing. The filter element, made of highly porous cardboard impregnated with special resins, can be in a metal mesh to increase the rigidity of the frame, and without it. You need to be careful when tightening the nuts on the filter cover and do not overtighten them if there is no metal mesh.
