Fuel Pump








*) Minimum delivery cubic cm/30 seconds.
**) Voltage at fuel pump with engine stationary and pump running (approx. 2 volts less than battery voltage).

The fuel pump delivery range is dependent upon battery voltage.

Example: During the test a voltage of 12.2 volts is measured at the battery. As pump voltage is approx. 2 volts less than battery voltage then this equates to a minimum delivery of 550 cubic cm/30 s.
