I have a base model 06 envoy 4.2 can’t find fuel filter, it is not near the tank. Had hard time finding temp sensor was on the back of the head on passenger side.
I have the exact same year model and engine and there’s no in-line filter to be found. From the research I’ve done it appears that the later model 06’s and up do not have the in-line filter, they have the filter sock on the bottom of the fuel pump. Can anyone tell me anything different that I’m missing??

I have a 5.3 denali envoy 2007 do i have a fuel filter outside of gas tank
From what i understand the fuel filter is connected with the fuel pump, so it seems you would have to drop the tank at least enough to pull the pump assembly out of the gas tank. I’m not 100% sure what years used this snd which didn’t, but if you don’t see a filter either in front or back/ right around the tank then it must be in the fuel pump. Consult with a professional or check with your manual, but I was told this when I too could not locate the filter anywhere.
