There are impact wrenches and there are impact wrenches. The point is not to apply great torque but to do it pressing down, not off to the side. If you apply enough torque to shear the bolts holding the Lisle tool together, or spread the little fingers, you've got bigger problems than figuring out which tool to use.
But I'm glad the CTA tool worked out well for you. Who knows, I may end up buying it anyway.

My tool bin includes 3 ..2post lifts. 2 star systems lots of older MB trouble shooting equipment for the 80’s and 90’s MB’s. Between 5 different 163’s and 164 chassis I have managed to put on over 400k miles maintaining them. Always asking questions and when I can giving some advice.

Eric thanks for your helpful tips on how to use a LISLE tool. IMO they are junk. I hope I save some future people the headache . Since I have had the pleasure of using both tools i have a strong opinion.

Eric maybe you need a few more hobbies! 😂
You do realize that a tool that grabs 2 plastic points vs a tool that grabs well over 20 well maybe you don’t realize….
By the way who changed your fuel pump? What tool was used?

Some of us don't have 20k square foot shops with five four-post lifts, a constellation of stars, and a plasma rifle assortment. Some of us don't want to or cannot afford to spend $65 on a tool we hope we are going to use once.
Some of us are able to use the $20 tool.

You are commenting on something like you were at my shop watching the 2 contacts peel off the plastic? Once you buy the proper tool I will accept your “you were right” 😂
😂 at least you provide after work hour entertainment..I thank you for that 👏 !!!

Final wrap up post
Installed the pump tonight and it fired right up.
1. Buy the full circle tool.. some people have been able to remove the ring with the 2 post tool .. I can tell you it is much safer,easier and smooth to use a tool that contacts the whole circle.
2. My 2008 did NOT have a fuel pump controller so it will not throw codes about fuel delivery like a 164 with a controller which will have feedback to the computers.
3. Cleaning up the lid I use a heat gun (away from the car and tank) to help scrape the old sealant (probably a urathane base) .. the heat made it a little more pliable.
4. No codes no warning just a quit on the side of a mountain road.. checking for fuel pressure by just pressing the common rail test port to see there was NO pressure of fuel.
5. The tool that helped me cut under the inspection cover lid (under the rear seat) was my favorite Golf grip removal tool. Hyde knife .. I sharpened the end of the blade than used a rubber mallet to slide it under and cut away the caulking . The blade is thick enough to hold up to pressure but thin enough to slide under without distorting the circle plate.
