Though a Ram post, my filters got water in them 1st part of Feb and then Temps went waaaaaay south and subsequently gelled up on my '15 6.7. Unable to get into dealer, they suggested I go to their sister dealer who works on trucks (Lincoln dealer). went there and that's when I was told it gelled up. Total cost for everything would've been 350 bucks(100 for dia, 100 for labor and 1509 for filters). Told them I'm NOT paying 150 for filters or 100 bucks labor (1 hour or 8/10 as I was told that what the book says). Buttoned it up, drove home w/o any problems. Next day got filters from NAPA for 85 (retail was 114). Short while later, ordered 4 from Dieselfiltersonline for 50 bucks along w/oil filters. No shipping fees. BTW, having never done a fuel filter cahnge before on the 6.7, yes it did take me an hour, but now that I know what to do, next time should be 20-30 minutes.
