    Trying to replace the DEF filter on a 2012 Hino 338. Can anyone tell me where it is located? I cant find anything that resembles this filter anywhere on the truck. Thanks for any help.....

    I believe a lot of them are in the def tank.
    As soon as GreasyTShirt shows up you’ll have the exact answer.

    Directly behind the DEF tank is the dosing pump. The filter is hiding under a cap with a 27mm, 12 point head on it. You access it from underneath. You will get DEF in your armpit. Don't put any lubricant on the o-rings, just shove it firmly into the hole. Don't forget the butt plug, that gets stuck up in there too.

    It'll make perfect sense once it's taken apart.
