you can get those glass fuel filters at most any auto parts store. autozone, advance auto. probably napa too, but i havent actually seen one there. im sure they have them though. they look nice. but they are kinda expensive. like $18 or so. and they only have a screen style filter in them. so i rather go with the cheaper plastic fuel filters with the paper element in them. paper filters are better. they catch more particles.
actually on my bike i use 3 filters. i have the petcock filter in the gas tank, i have a small in-line screen filter, meant for a lawn mower or the like. and then a clear plastic paper in-line filter. aint nothing gonna get through that...
the glass ones are the best on looks.. and probably over all quality. although it is glass. and i tend to always break things. they are thicker glass though. if there was a glass one with a paper filter i would buy it. but i havent seen one.
