  1. 2006 Chevy trailblazer LS
    Isn’t located in front of fuel tank nor rear. I see the fuel lines running on top of the tank but no fuel filter

    1. I just had same problem. there is no filter. it is actually a fuel screen and that bad boy is in the fuel tank as part of the fuel pump assembly. Si I got a new fuel pump from Rockauto for 70.00 and dropped the tank and replaced the whole unit. time consuming but is gonna be worth it in the long run. it fix the fuel gauge problem I been having.

  2. Apparently the fuel filter is an integral part of the fuel pump sending unit that is inside the fuel tank there is no external fuel filter from 2003 through 2008

    1. Then why does the tech support and internet and mechanics and auto supply say there is one from 2003-2005 in 06 up there is not.

  3. Don’t forget to change your turn signal fluid, too!

    Just kidding, but this site is an absolute joke. Chevy stopped using fuel filters in 2005 for the TrailBlazer. 2006 and beyond utilize a filter that’s actually in the gas tank.

    You’d think the top-notch mechanics behind a website like would understand that, but it turns out, no, they don’t.

    Hopefully this saved you some time from searching if you’re working on a 2006 or beyond Blazer.!

Don’t have time to take the Bloody thing of again so can i install an inline filter at the end fuel connection at the tank? Pain in the a—

  5. I just (8/28/2021) changed the fuel filter in my 2003 Trailblazer LS. It’s located exactly as stated in the article above. The entire job took fewer than 30 minutes from the time I put the TB on the lift until I put it on the ground.
