If the filters look clean and you don’t see any water when you open the drain save your money and leave them alone.
A fuel filter is designed to catch particles that are perhaps 2 microns or less. As they become loaded with contaminants they actually do a better job of cleaning the fuel at the expense of flow.
When the engine feels sluggish & won’t run at rated speed & load that is when you must stop & replace them.
Unlike engine oil filters that can restrict flow and go into bypass mode allowing contaminants to bypass the filter & cause engine damage fuel filters have no bypass feature.
Recommended schedules are conservative to avoid unplanned downtime.
I have a 28hp 1720 Ford compact tractor with a very very small fuel filter that I rarely replace because I fuel up from an inside bulk fuel tank with 3 filters. The first filter is 10 micron 2nd is a 2 micron and 3rd is a water block/10 micron.
The last time I replaced the filter was because the o-ring was leaking, filter was clean.
