I am one of those 2 to 3 times filter guys. I filter the gas from the can to the tank and I use one of the filters that look like crap (dubro aluminum) between the tank and engine. I am slowly switching the fleet (25+ airplanes with multiple fuel tanks) to add a clunk felt filter. In spite of the effort, I accumulate junk in both the fuel can filter and the in line filter. All filters receive an annual cleaning. I am thinking of going to an inline auto filter in the pickup line in the fuel can (we use 5 gal fuel cans).
