RE: Adding fuel line filters ...
I've never used filters on my planes before, but I'm considering using one now for my 4-stroke muffler tap. A lot of junk is getting into the tank from the muffler. This seems to happen only with 4-strokes. I guess the 2-stroke exhaust is not as hot.
How has using a filter in the pressure line worked out for you all? Do you notice that the tank stays cleaner?
