Today I changed the fuel filter on my 06 DuraMax. My first time doing it myself just wanted to say what a breeze. Maybe an hour total including the reset on the DIC. Kinda fun. :)
Hi, congrats you have saved quite a bit of money doing it yourself . I have an 06 also. My first change took me about an hour, but is about half hour now. The only thing I remove is the air intake boot. I use an oil filter wrench to take the filter off. The hardest part for me is the o ring on top of the filter never wants to stay in place.
