ACDelco TP3018 Professional Fuel Filter with Seals

100% correct filter. Acdelco gm genuine blue filter that came with the 2 proper O rings and even came in the right box. I’m always buying my Duramax filter from this supplier now

Its a fuel filter with seals. It was the one I needed. Works fine. Original AC Delco filter. Not much else to add...

Easy to fit to the Chev Duramax and works great

This is as good as any of the replacement filters, very reasonable price ($31 at Amazon as of this writing) vs. auto parts stores $50+. If you have changed one of these yourself then you know dealing with the filters large o-ring is a major pain. That o-ring just will not sit in position until you get it placed at the filter housing to attach it - no matter if you use oil, deisel or grease to help hold it. For me the best way to do it is to also stretcchhh the o-ring a couple times like a rubber band - not TOO much or you will damage or even break it !!!! It will then sit in place for a minute, maybe two, before rubber "memory" causes it to pull in and buckle out of position. Stretching will only give you a short time to get it in place so don't lollygag around. Also you have to push the filter up into the fuel filter housing agressively to get the threads of the two parts to meet so you can spin it on. One more note - don't forget the fuel bleeder screw o-ring. Those plastic bleeder screws are a joke (get a metal replacement) but the o-ring ages and needs replacement too. Mine is a 2003 Duramax and that o-ring developed an air leak causing hard-acceleration hesitation, reduced power, hard start and no start issues.
