Definitely. Part of the fuel system service is to drain this filter to remove water. I haven’t heard back from Exmark re how often the element should be changed out.
NAPA used to sell diesel fuel filters with radiator-type water drains on the very bottom. That was nice because you could drain without taking the filter all the way off. Another filter maker, Raycor, had a transparent bowl so you could visually inspect.
Thanks. Exmark indicated it should be changed between 250-400hrs. Funny that there is no reference to doing so in the manuals provided to the consumer. Maybe its referenced in the workshop manual which they wont provide to those of us that like to work on our own stuff.
