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 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 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.
