i think that there are three fuel filters on my 48. One close to the tank, one just in front of the fuel pump and the little one that goes in the carb. Over the years they plugged up at alternate times.
Exactly what type of **** is it? Brown, soft and formed? (lol...just bein' an ***) Or...is it white powdery ****? If so, it's probably due to the **** gas. (ethanol) It eats metal, and can deposit the white ****. Otherwise, just impurities form the gas-staion, or rust particals from your tank. In that case, clean your tank and upgrade on the filters...more of them, and a good grade.
