GM Genuine Parts TR26 (10325852) Fuel Tank Lock Ring (Right)

Fit perfectly but be warned, these things are quite a challenge to get locked down with even old seals. The trick I found, thanks to the YouTubes, is to take a pair of locking pliers and get them set up on one flat of the ring and then use a pair of large channel-lock pliers directly opposite to squeeze the ring and the tabs together. Spent 2 hours with brass punches, air hammers, and sledge hammers and this little trick worked like magic. It came with GM hologram stickers on the package so I'm certain it is OEM and it was identical to the original OEM that I removed.

Great fir

I typically buy a replacement ring when I replace a fuel pump and that’s usually when a vehicle is 10 years old or greater and at that time, the old ring is more of a rust ring. I also buy high quality fuel pumps so I don’t have to repeat the labor for another 10 years. AC Delco or Delphi are great brands. I also take the time and clean the tank to prolong the life of the new pump. I know that’s a lot of extra work but it’s always a pain to change these so why not do a ‘once and done’ you and your time are more valuable then dinking with a new pump every year or two. I also tend to ding up the metal on the ring a little when I install (a few nicks) with a large screw driver and a mallet so I touch up with black Rustoleum to prevent rust. I have an install tool but don’t like the tool and prefer the large screw driver and mallet method. The ring was a perfect fit for my application, 05 Escalade.

AC DELCO there is no substute for quality

Just the right one, just like the original

genuine gm and worked perfectly as a replacement

This is a nice,well made lock ring.It fit the tank on my 2008 Avalanche perfectly.For the price,I would recommend getting this whenever you have to change the fuel pump,even if the old still looks good,it's cheap insurance to go ahead and replace it since you have to remove the old one anyway.

Was super hard to get the old one off the avalanche tank. had to make a tool to remove old and put on new. Buy the tool they recommend to go with it and save all the swearing. Once installed, it was a perfect fit for the sending unit.
