im always careful of the wind when im mixing and refilling as a gust can whip fine dust into your tank,gascan,or oil measure pretty quick and its the finest grit that will make it through to engine.flexi spouts left outside of gascans make great dust traps too.gravity fed systems aren't so bad as the filter will just block and starve engine,annoying but not critical IMO.with pressurized fuel though as the filter blocks the same volume of fuel gets forced through a ever decreasing space,raising press on filter medium,which in extreme cases can begin to fail and then crud gets forced down the line...not great for injection systems
higher quality filters will take much finer contaminants out,the catch is they clog faster.if its blocking once a year its doin a good job and proves its worth.if it stayed clean for years it would prove its uselessness!
