I'm got an 83 300d and have changed my fuel, and the tank seems to be cleaning itself. I'm changing the inline fuel filter constantly, and have noticed they have really gone up in price. The ones I use seem to be sturdy, wondering if there is a way to clean them (provided they aren't that dirty). Seems a shame to toss them if they somehow can be cleaned and re-used. The filters aren't black when I change them but I'm doing it often as my car almost came to a halt a couple weeks back because of a dirty fuel filter. Anyone out these tried to clean the filters? Thanks
