Make sure there is no fuel left in the sensor and then set the meter to the
"Impedance" scale and measure across the BLUE and WHITE wires. Cor-
rect value is as follows: 1.3 KOhm (+/- 10%) at 20 °C.
B: pump operation
Connect the RED (+) and BLACK (-) wires to a power supply unit with con-
stant 12V output and make sure that the pump runs.
Never keep the pump connected to the power supply unit for more
than 3 seconds in a row.
