Attention! Check the fuel supply pressure in the idle mode.
Checking the fuel supply pressure must be carried out in the following order. Prepare fixtures «13.6.030» And «13.5.222», protect the generator from pollution and connect «DIS tester».
Connect fixtures «13.5.222» And «13.6.030» between themselves (pic. 6.118) into a single assembly.
Open quick shutter (1) return pipeline (2). Connect the pressure sensor with a quick-release fastener to «DIS tester». Insert fixture «13.6.030» between fuel lines (1) And (2).
Start the engine, bring it to steady idle mode and record the fuel return pressure from HP to the fuel tank, which should be within 200–300 mbar.
Rebuilding the engine should be carried out in the reverse order, if necessary. Stop the engine, remove the tool assembly and connect the fuel hoses. To remove air from the power system, it is necessary to turn on the ignition for about 1 minute. During this time, the fuel priming pump is activated and the fuel cooler is filled with fuel, forcing air out of the system.
