A method for monitoring fuel quality of a power system used in transport, the method comprising: a controller of the power system determining that the prime mover is actively running; the controller monitoring an output of a water-in-fuel (WIF) sensor configured to determine whether a threshold level of water has accumulated in a water collection reservoir of a fuel/water separator that separates water from fuel passing there through; the controller determining an amount of fuel passing through the fuel/water separator ; the controller calculating 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 ; and the controller triggering different alerts based on the calculated fuel quality score, including: the controller triggering an alert to check the water collection reservoir , an alert to check the WIF sensor , and an alert to check a WIF sensor connection to the controller when the fuel quality score is above a first fuel quality score range; the controller triggering an alert to drain the water collection reservoir when the fuel quality score is within the first fuel quality score range; the controller triggering an alert to indicate low quality fuel when the fuel quality score is within a second fuel quality score range, the second fuel quality score range being a lower fuel quality score range than the first fuel quality score range; and the controller triggering an alert to service a fuel tank for storing the fuel when the fuel quality score is below the second fuel quality score range. a controller of the power system determining that the prime mover is actively running; the controller monitoring an output of a water-in-fuel (WIF) sensor configured to determine whether a threshold level of water has accumulated in a water collection reservoir of a fuel/water separator that separates water from fuel passing there through; the controller determining an amount of fuel passing through the fuel/water separator ; the controller calculating 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 ; and the controller triggering different alerts based on the calculated fuel quality score, including: the controller triggering an alert to check the water collection reservoir , an alert to check the WIF sensor , and an alert to check a WIF sensor connection to the controller when the fuel quality score is above a first fuel quality score range; the controller triggering an alert to drain the water collection reservoir when the fuel quality score is within the first fuel quality score range; the controller triggering an alert to indicate low quality fuel when the fuel quality score is within a second fuel quality score range, the second fuel quality score range being a lower fuel quality score range than the first fuel quality score range; and the controller triggering an alert to service a fuel tank for storing the fuel when the fuel quality score is below the second fuel quality score range. the controller triggering an alert to check the water collection reservoir , an alert to check the WIF sensor , and an alert to check a WIF sensor connection to the controller when the fuel quality score is above a first fuel quality score range; the controller triggering an alert to drain the water collection reservoir when the fuel quality score is within the first fuel quality score range; the controller triggering an alert to indicate low quality fuel when the fuel quality score is within a second fuel quality score range, the second fuel quality score range being a lower fuel quality score range than the first fuel quality score range; and the controller triggering an alert to service a fuel tank for storing the fuel when the fuel quality score is below the second fuel quality score range. <EOS>
