2015-2017 Duramax Fuel filter access

Check out this fuel filter access panel kit from Mad Jack Diesel. Not only is helpful when changing fuel filter. Gives you easy access to open and drain the water separator.
See attached (I hope) screenshot.

Sorry 2015 & 2016

Just did mine, needed to remove the inner wheel well, this looks like money well spent. I will definitely look into this !!

Was worth the dough. Instructions say to remove wheel well liner in order to mount panel, I choose to take the wheel off and used a dremel with a thin cutting wheel to cut the liner. Just need to be careful when cutting and drilling holes, there is an AC line behind the liner. Liner has enough flex that you can pull it out some while cutting and drilling.

2017 they moved the filter under the truck and it's easer to change.
