In order to replace my in-tank fuel pump, I have to drop the tank and remove the sending unit, which is installed through a hole on the top side of the tank.
There's a tool that is used to remove the lock ring that secures the sending unit to the fuel tank. I did a search online and was surprised to find out that these tools are very common.
So now I don't know which one to pick! Do they all work because it's such a standard thing? If someone has one that works on the ring on a '76 - '79 tank, can you please tell me which one to buy? Based on the service manual, it sounds like the Eldo and Seville had the same sending unit during this period.
Thanks!

I have always tapped the lock ring loose with a small driver and hammer.
I have known people with tools and it didn't seem to help much. If it wasn't rusty you could work them out with a hammer and punch or screwdriver. If they were rusty the tool just slipped off and mangled things and you still ended up destroying it.
OK. Thanks guys! I saw a video of someone using a pin and a hammer to get it off. I just assumed the tool would be easier. My guess is that this is not the last time I will have to do this, ha.
I always managed using a flat end punch and small
hammer, working my way around the ring a few times.

I use a brass drift and a hammer. When you do it sometimes the lock ring will shift slightly side to side. If you take turns tapping around different areas of the circumference it will tend to center it a little more; tapping from a side where it's getting closer.
When I installed the new sending unit the original lock ring fit a lot nicer than the replacement. By memory the form was a little different and it made it very tight, maybe too tight, to install so I used the original.
If you look on Rock Auto for sending unit lock rings and then you look up the application you will very likely see MANY vehicles use the same number. Doing that you can probably find a tool which will work under a different car listing if your car isn't listed. I've never used one but if the interact with the tabs a little nicer and they keep the ring centered turning install I could see how one would be helpful.

I never had the tool, never felt a desperate need
for it. But I really wonder of its effectiveness
on a ring that has gotten pretty much stuck in one
position for a long time? Tapping around the edges
can break loose one area at a time, instead of
trying all of it at once. Bruce Roe
