Fuel Pump








- Fuel pump delivery range is dependent upon battery voltage
- Operate remote control for 30 seconds.
- Compare quantity of fuel delivered with chart.
*) Minimum delivery cubic cm/30 seconds
**) Voltage at fuel pump with engine not running and pump activated (approx. 2 Volts less than battery voltage).

Example:
During test, 12.5 Volts is measured at battery. The fuel pump voltage is approx. 2 Volts less than battery voltage equating to a minimum delivery of 530 cubic cm/30 s.
