*) Minimum delivery cm3/30 seconds 
**) Voltage at fuel pump with engine not running and pump activated (approx. 2 Volts less than battery voltage).

Example:
During test a voltage of 12.5 Volts is measured at the battery. As the voltage at the fuel pump is approx. 2 Volts less than battery voltage then this will
equate to a minimum delivery of 200 cm3/30 s.
