2014 ML350 bluetec DIY fuel filter change
I'm trying to DIY this nasty fuel filter change for my ML for the first time. With the pdfs (dm me if you need those!) from WIS and a few YouTube videos, the instruction seems to be pretty clear. Have anyone done this before, and is there anything that I should be particularly careful about?
Also, do I need those thread lockers on the screws when re-installing everything back?
