I have 3,2005 IC DT466 EGR Engines, Fuel filter light always coming on. Replaced filter and fuel pump, I even changed primer pump and pressure regulator. Fuel pressure is 50-55 psi. Has anyone had this issue, and what did you find works!
Most the time the fuel pressure regulator is the issue ive found but if you have a heater on the bottom cover check that sometimes you get a pinhole in the plastic by the plug.
Have you done any diagnostics on the sender that's on the backside of the filter assembly? We occasionally have had one of those out of range. P/N 1839415C91 used for EOP and EFP.
No i haven't checked that yet, we have about 4 buses with the same problem and our admin wanbts us to install a racor filter but there isn't a proper way to splice the suction line that i have found. I've changed everything else on the fuel system on a couple of the buses also. I will check the sensor today on oneof them and see what i find.
Our international dealer suggusted we let them reprogram our busses to set fuel filter changes to 999,999 miles between changes which we will never see
