Bill, this is the first fuel filter that I have installed on a bike, I thought that the petcock stand pipe on my R65 had a metal screen, but I am wrong, at least on my bike. Every time I removed the carb float bowls, I always found a fair amount of fine grit and a couple of globs of water as well. I've had this filter on the bike for about three years, and I found no grit or water this time, and it has been three years since the float bowls were last removed and cleaned. So I guess that the filter did it's job. I did a search of the Visu-filter web-site,and they have a high flow filter, with about 15 times the filter surface area of the sintered element filter that I have now. Cost is about $3, only down side is you have to order them, and shipping costs about as much as the filter itself.
