Duramax fuel filter housing

(PA) | August 7th, 2020
I was skeptical at first. Price ranges were all over the map. The fact that it came with an AC-Delco filter was reassuring. Fitment was flawless. If its not OEM it sure fit like it was. Installation was a breeze. Just remember to start both bolts bolt, 2-3 turns, together before attempting to seat them.

1198525 My Duramax died on me. At least it was in the yard. Convenient for me. So I identified the problem and within minutes I had it ordered from XTreme. Amazing service and was shipped out next day. Has worked flawless. I’ve replaced it twice now the factory replacement from you is way better than the eBay special I did the first time. I’ll be ordering from you from now on.
Great item

Most Popular Questions

Will this work with my LB7?
View Staff Answer 
Answer

The GM 12642623 is a direct fit for 2004.5-2010 GM 6.6L Duramax 6.6L.

That being said, the Fuel Filter Head Assembly can be used on LB7 applications. This requires additional fuel line and rerouting to work properly. (You will not have the ability to reconnect the filter head heater wires. This will not cause any CEL’s or issues.)
