Fuel Pressure

Fuel Pump, Checking







- Compare the quantity of fuel delivered with specification.
*) Minimum delivery cm3/30 seconds
**) Voltage at fuel pump with engine stationary and pump running (approx. 2 volts less than battery voltage).

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