Any members who have tried this partial flow system, and what kind of results are you getting, especially if you tow commercially. I presently have the Frantz for over 300k w/ regular analysis and no real complaints. I don't like black oil, even when it is translucent and the analysis always says go longer. Watched their video, wow. What about real world and how much is the cost of the replacement filter for 10k service (about once a month for me) Also is there a fuel filter relocation kit for my first gen ?
