Fuel tank sending unit
Do you have your old ( assuming OEM) sender. DO NOT TOSS IT! I would be interested in it working or not.
The lock ring has 3 nubs on it. The tank ring has 3 sets of 2 nubs. the ring nub gets turned till each of the ring nubs are between the tank nubs.
This image is not what your sender is going to look like but it will give you an idea, also the nubs on this tank are one recess rather then two nubs seperated by a space as I was thinking.
Properly seated
I highly recommend this tool, you can do it with a screwdriver but the right tool for the job is always better.
