has anyone listed a list of filters that are bigger than some common ones? for instance, i used st3614's, only to find out i can use st3600. the 3600 is bigger.
If the ST3614 is a 3/4-16 thread filter (IIRC, it is) ..then you've got just about any size filter you can imagine. Most of the gaskets are within .1" of each other ..with very few exceptions. The only limit is your capacity for bigger diameters or longer lengths ..or ground clearance.
..but in the ST line you're looking at the ST16 or the ST8A. I don't know if they have an FL300 equivalent.
