I believe in gascolators...I've had several of those little glass filters skim over from this crappy gas we got nowadays and had fuel flow problems from that. The skim didn't show when looking at it thru the glass. I've never had a gascolator do that. And as noted from the pic, even if the gascolator isn't located at the lowest point theoretically it should catch and hold any water that passes thru. the ones I run will hold probably 4 oz anyway maybe more...if you got more than that in your tanks you got fuel handling problems
i did away with all my filters and run gascolators religiously.
