HELP!!! 2004 Yukon flex fuel lock ring for fuel pump...

If you haven’t gotten that apart by now I have a feeing that even if you get that ring off you will find that the tabs on the tank side are rusted too. You will likely need to remove that ring in pieces. You probably need a different tank.

I haven't been able to work on it because of my work schedule. I'll take another crack at it this afternoon. Just got home from work, so I need a nap.

Welp, a different tank it is. I went out on a limb after soaking the lock ring for days in PB blaster and then bashing it with a chisel and hammer. More chunks flying.
