| Compare quantity of fuel delivered with specification. |
1)
| Minimum delivery cm3/30 seconds |
2)
| Voltage at fuel pump with engine not running and pump running (approx. 2 volts less than battery voltage). |
During the test a voltage of 10.5 volts is measured. At this pump voltage, the minimum delivery rate is 540 cm3/30 s. |
If minimum delivery rate is not attained: |
–
| Check supply line to filter for possible restrictions (kinks) or blockages. |
–
| Check fuel delivery rate before fuel filter. |
WARNING Fuel supply lines are under pressure! Wear eye protection and gloves to avoid injuries and skin contact. Before loosening hose connections, wrap a cloth around the connection. Then release pressure by carefully pulling hose off connection. |
