Pump gas isn't exactly loaded with contaminants and debris. In the old days, metal tanks would scale and rust creating all kinds of nastys to get trapped in filters. I went crazy and chopped my filter in half to inspect the element. It was discolored, sort of gray but definitely not clogged with scary stuff. I'm leaning toward a weakened pressure regulator or as Soildjake mentions, a fresh pump pushing the juice harder.
May never know what performed the magic but nice to see others noticing an improvement as well.
