I have the Lock Technologies one (LTI on Amazon) and have no complaints. I did have to notch it a bit to fit a mercedes ring, but other then that, I haven't found a lock ring it cannot do. The Lisle one looks like a stout piece as well. Don't think you could go wrong with either. Hammer and a screwdriver are a bad idea when those plastic rings get some age on them and get brittle.

Ya that is why I want to go ahead and pick up the right tool. I've never worked on any mercedes so that shouldn't be an issue. Will the LTI one work on the metal GM lock rings like this also? https://www.google.com/search?q=gm+...fuVJ6DE8zagwSU8ILoBA&ved=0CAcQ_AUoAg#imgdii=_

I too have the lock technology tool. It will work on the metal ring GM pumps, but only at certain angles, as the fuel lines cover some parts of the ring. For those, I still use a small hammer and chisel.

I've never tried to use it on the metal GM rings. I have a brass drift that now has the perfect indentations in it where it won't slip off. If I lived in an area where rust was prevalent, I would probably grab one specific for them. Heck, I might even throw one in on my next order since we're talking about it lol.

I've always used a punch also but with rust and age I get scared of breaking one. Which tool would you get for the metal GM ones?

If these guys claim the lock technologies tool will work with the GM pumps, I'd go with that, since it is versatile enough to do all the pumps with plastic rings too. I'm putting a tank in one on friday, so I'll know for sure then if it will work and let you know if you have the time to wait.

I got the OTC 6599 for GM's, but haven't used it yet. Reviews are good.

Ordered after a particularly tight ring on my Suburban and very strong pump return spring. Taking 'em apart is rarely the issue, it's putting them back together where you find yourself wishing you had some way to push down concentric on that ring while simultaneously twisting into place. Sounds like something a specialty tool might do :D

My messed up thinking says to order it from TT since it's cheaper and then add another 62 dollars of tools just to get the free shipping! We don't all think like this? :lol_hitti

Hey, I wasn't gonna be the one to say it, figured someone would pick up on it lol :beer:

Channellock oil filter pliers (#215?)work good on those plastic rings. Have the lisle tool also and it works on the plastic rings but is slower to use and costs more. Can't see how that lisle tool would work on the metal rings.

For the record, the Lock Technologies tool will not work on a Trailblazer. However, that is one of the easier ones to pop on and off with a drift and hammer.

I find that there's some where 1 screwdriver and hammer will just break off the tab you're pounding on. If you have a helper, then the 2 of you working 180° apart will make them come off like butter. It's real fun if you're doing it through a hole in the trunk floor. :eyecrazy:

This was why I am looking for a correct tool, or looks like in this case I will need tools to do all the lock rings. I've had some GMs that were rusty and using a punch and hammer I was a little worried it was going to break, one saturn I remember in particular.

For the plastic lock rings, couldn't you use a strap type oil filter wrench?
