I have a 2007. 5 1 ton 6. 7L... I just got the truck and was changing the oil and everything. i went and bought a fuel filter and the guy at napa asked if i needed just the filter or the housing to. . he said that if it's the first time you changed the filter that i would need this. . What the hell is he talking about? isn't it just a cartridge filter like the 5. 9L's? i haven't changed it yet. i wanna see what this is all about. . Any info will be great thanks
