Hi there. Just a quick question regarding in-tank fuel filters. This question is relating to chainsaws, hedge trimmers, and weed trimmers. Is there such thing as a generic fuel filter that would work in various makes and models of power equipment, or does one need to run the specific one to each piece? I am just curious as my dad and I work on various makes and such, but would just rather buy a few filters and use them than order each one specifically for the tool. If they are brand specific, what or why would the reason be? If I can get away with a generic one, would it be better to buy ones that are smaller, bigger, or something in between? I do see they come in various designs and sizes. Just trying to learn things slowly. Thank you in advance for any and all help and opinions.
