In this article we consider what should you do in the event of faults or planned maintenance Fuel System Chevrolet Niva. First, you need to know that if the engine with fuel injection, the pressure in its power supply system 30 MPa, or something the same, 3 kgf/cm2. So strictly prohibited aperient nuts that connect the fuel line when the engine is running and even after stopping the latter. Before working with the power system, we must reduce the pressure. So, after a few hours after the engine stopped, the pressure injection system drops to zero.
How can I reduce the pressure injection system, if you wait a couple of hours not want to? Let us examine the sequence of actions. Take a socket wrench, "ten." Unscrew the nut that holds the cover of the engine control unit, then to remove the lid and remove the fuse elektrobenzonasosa. Start the engine, let it will work until it consumed all the fuel in the fuel. When the engine stops, insert a fuse in place.

Take a screwdriver and remove the screws that attach the filter cover. Lift this cover, remove the filter element. Put now a new element, with notice to the new item was exactly as the old one.
