Inline fuel filter specs

[Cupwalker]

Never paid any attention to the filtering specs of inline fuel filters because honestly I didn't know there were different micron levels available or so it seems. The reason I said "or so it seems" is because I recently saw the filtering specs in a listing for a fuel filter and I can't think of any other reason why it would've specified the micron level if there weren't other options available. The only criteria I've always had when buying fuel filters was...will it fit the fuel line I have and does it look similar to what I'm replacing...but now I'm wondering if I've been overlooking important aspects. Aspects that could possibly play a vital role in performance or vital to the longevity of other components? So maybe someone can answer this. Is there a specific micron filter that should be used per the hp of an engine or size of fuel pump etc? What do you guys think? Thanks...Cup

Don't think so. I would get a good quality in line filter rated for gas engines. I have seen lawnmower engines using anything from El cheapo (not recommended but better than nothing ) filters to expensive car filters. Both filtered and didn't impede the fuel flow. In all the years working with mechanical things the only time I was concerned with filter microns was with hydraStat trans. Some are very specific especially working on warranty machines.

That's always been my take on the situation as well but when I started seeing micron filtering capabilities noted in the listings it made me wonder. Thanks for the feedback...Cup
