Method and system for fuel filter monitoring

A fuel filter monitoring method for a fuel supply system including a plurality of fuel injectors, at least one fuel filter upstream of the one or more of the fuel injectors, and a sensor system configured to detect at least one of a location, a barometric pressure, or a fuel temperature associated with the fuel supply system, the method comprising:

• receiving a signal indicative of at least one of the location, the barometric pressure, or the fuel temperature;
• determining a remaining life of the fuel supply system based on a pressure drop across the at least one fuel filter and the received signal;
• modifying a rate of change of the remaining life while a temperature associated with an internal combustion engine and a pressure drop across fuel filter remain constant;
• and
• outputting a notification indicative of the remaining life of the fuel supply system.

A fuel filter monitoring system, comprising:

• an internal combustion engine that receives fuel injected by a plurality of fuel injectors;
• a fuel supply system including at least one fuel filter connected between one or more of the fuel injectors and a fuel source for supplying fuel to the internal combustion engine;
• a sensor system configured to detect a pressure change across the at least one fuel filter;
• and
• a controller configured to:
• estimate a remaining life associated with the fuel supply system based on the pressure change,
• identify a characteristic of the at least one fuel filter based on a rate of change of the estimated remaining life, and
• output a notification indicative of the characteristic of the at least one fuel filter based on the estimated remaining life and the rate of change of the estimated remaining life.
