Changed my fuel filter for the first time yesterday. Display said 29% but I didn’t want to go any longer with it. Nothing to it really. I bought a GM filter from Rock Auto. They had the best price $27.00 plus tax and shipping. Priming the system worked without a hitch.
Drained the catch can today. It had roughly 3 or 4 ounces of milky looking oil/water in it. I guess it’s working!
I need to run a longer hose down under the truck to make draining it easier.
A friend of mine owns a machine shop so it only cost me $70 for the aluminum and $27 for the special tap.
I would think most machine shops would charge $250 to $350 to machine.

Has anyone tried this adapter for the fuel filter. Seems like a good upgrade.
I haven’t done much towing yet but when I have it does regen more often. That said I’ve only filled my def tank once in 18k miles. I will need to fill soon as I’m down to 32% full. Planning on inspecting the injector to see how it looks.
This is my normal week to week local driving. I recently ran two tanks without any additive and my mileage was almost 2 mpg less. I’ve been using the Hot Shot Secrets.
Catch can installed. No easy task but don’t rush it I did buy a pair of clamp pliers which worked well. Everything is a tight fit. I took the two fittings off the catch can which made it easier to install. Hose clamps are a pain but I used the supplied ones.
