I changed the filter on the Low Rider at 40k, the RGL at 25k, both were very dark, 25k is the max I run them now.

My 14 SGS Fuel Pump started making a very intermittent "screaming" sound when powering the bike up about 25,000 miles ago. Started a new thread about it here and decided to change the filter/regulator on it before a trip. It really had little effect on the noise. It reminds me of a fan motor shaft chattering in a bronze bushing when it gets worn a bit. The bike is getting torn down this winter for a motor refresh and I will change out the whole fuel system in the tank at that time.

Had the fuel filter canister fail about 1000 miles after a fuel filter change. Even at that low mileage the filter was quite dark. My THEORY is that the filter material turns dark in a gasoline environment regardless of whether it is dirty or not.
