Ah, but there is another filter in our first gen fuel delivery systems; there is a 'sock like' filter bag over the inlet inside the gas tank. I have seen it many times when the sock gets ripped due to weaking from age and rust. When the sock gets ripped it actually traps particals inside the sock and it becomes a detriment instead of a helping factor. The regular metal can filters work great and can collect ten times the amount of particals a stock in-carb filter can. I like the way Greg has his.
