UNKNOWN I had performed preventative maintenance this evening, fuel filter replacement and noticed after I pulled the fuel filter from the housing and tipped housing back upright, there was what appeared to be brass/gold metal shavings in the bottom of the housing in a little puddle of fuel. If there is metal shavings in the filter, that is a problem.
