| 1. To connect the voltmeter by means of additional wires to the fuel pump. To press remote control, to measure and write down the measured size; about 2 V less than tension of the rechargeable battery of 12 Century. |
| 2. For elimination of excessive pressure to open and close a cover of the fuel tank. |
| |
3. To disconnect the pipeline of the return supply of fuel (1) from a branch. To connect by means of an adapter an additional hose with the manometer, to lower the second end in measured capacity. In the drawing the 4-cylinder petrol engine is represented. |
| 4. To include remote control, gradually closing the crane until the manometer shows 3 bars. To leave the crane in this situation. |
| 5. To release measured capacity. |
| 6. To include remote control for 30 seconds. |
| 7. In size of the written-down tension to determine the required value of the minimum quantity of giving by the chart. For example: to value of voltage of 10 V there corresponds the minimum quantity of giving = 500 cm3. |
| 8. To compare the minimum quantity of giving to the measured number of giving. |
Prevention
If tension is normal, and the number of giving nevertheless is not enough, to check whether are bent and whether fuel-supply lines are hammered, whether the fuel filter is hammered. If everything is all right to check the backpressure valve of the fuel pump.
