2. Before removing the pump, disconnect the fuel lines and clamp their ends properly.
3. Loosen the pump mounting bolts and remove the pump.
4. The filter mesh that needs to be cleaned is located at the top of the pump.
5. If the fuel pump is disassembled, mark both parts of the crankcase in advance so that they can be reassembled in the same way.
6. The pressure can be measured on the installed pump, and it is recommended to clamp the fuel line with clamps (see illustration).

8.6 Checking the pressure of the mechanical fuel pump
7. Connect the short transparent hose to the fuel outlet pipe connection. Make sure that the hose is not kinked.
8. Connect the pressure gauge to the other end of the hose so that it is next to the pump and the hose is S-shaped. The fuel level in the transparent hose should be equal to the fuel level in the pump. Only in this position can the static pressure be accurately measured and it should be 0.27 - 0.32 bar. Moving the hose or the pressure gauge affects the measurement results.
