If anyone can explain I would sure like to know
My 2002 ISC 350 fuel filter was so dirty I was loosing power on hills and lite never ever came on so iam thinking this was only on some models maybe?
NOTE that it was NOT his fuel filter, but his FUEL/WATER SEPARATOR that sent the signal so his unit was NOT starving for fuel so his power remained. The fuel/water separator is separate from the fuel filters on most rigs. Have you checked your fuel/water separator?
Fuel water seperater as I understand things is a primary fuel filter.I have a fuel filter with a water seperater and a secondary fuel filter.The seperater has a water in fuel warning but certainly not a stop engine warning the way I understand things? 2008 425isl
why I keep questioning the OP issue is that I cant see how or why Cummins would ever want the "stop engine" lite to come on just because the fuel filter was nearing its end of life journey
