    I lease a 2017 Pete 579 with the Paccar MX13, and it's due for a DEF filter change before too long. Has anyone done that filter change themselves, and if so, how? I'm talking about the DEF fluid filter, not the DPF.

    Pull the bottom skid plate off the def pump. Spin out the filter cover with a 12 point socket. R+r filter. Assemble. Easy peasy
