I'm about to change the fuel filter on my Cub Cadet mower with a Kohler XT 725 engine. I'm finding fuel filters with micron ratings from 15 to 75. What micron rating should I look for?

The Briggs and Stratton 695666 is a very good one rated at 30 Micron.

If the engine manufacturer does not specify, I would suggest a filter micron anywhere from 50-120. My feeling would be one more towards the 100

Reasons:
  • The engines fuel delivery system will be able to handle a certain particle size without damage or blocking. No point in filtering out these particles.
  • Too small a micron leads to more rapid blocking of the filter = more frequent changes = more cost for no discernible benefit.
Personally I preferer the "plastic' transparent body/casing, gauze media filters. These are almost indestructible, allow for inspection without removal, the gauze media will not breakdown/deteriorate, can be cleaned using compressed air but better to replace . Good examples are made by Baldwin & Hengst (be careful to select original manufacturer1749515590523.png1749515811775.png);

Is this a single cylinder Kohler engine? If so, it's a gravity fed unit. If you put too small of a micron rated filter on it, it will not run.
