Claim 10:
11. A power system for use in transport, the power system comprising:
a fuel system that includes:
a fuel tank for storing fuel,
a fuel/water separator configured to separate water from the fuel as the fuel is being directed to a prime mover of the power system, wherein the fuel/water separator includes a water collection reservoir configured to collect water separated from the fuel by the fuel/water separator, and
a water-in-fuel (WIF) sensor configured to indicate when a threshold amount of the water has accumulated in the water collection reservoir;

a prime mover configured to receive fuel downstream of the fuel/water separator; and
a controller configured to control operation of the power system including a speed of the prime mover, wherein the controller is configured to:
determine that the prime mover is actively running,
upon determining that the prime mover is actively running, determine an amount of fuel passing through the fuel/water separator,
monitor an output of the WIF sensor while the prime mover is actively running,
calculate a fuel quality score of the fuel based on the output of the WIF sensor and the amount of fuel having passed through the fuel/water separator while the prime mover is actively running, and
trigger different alerts based on the calculated fuel quality score while the prime mover is actively running.
