DEF filter

Just read the article about a DEF filter. I did not know there was such a thing. Has anyone done this? Where do you get the filters? How do you drain the tank to change the filter...any other tips...
Thanks!

  • I just saw the article on the DEF filter in my FMCA magazine. It says to change it every 200,000 miles or 2 yrs. whichever comes first.

    I, too, had never heard of it but will have it checked out at my next chassis service. We are currently at 38,500 miles and 2.5 yrs. :p

    Safe travels,
