Fuel tank/sender question

Well, that was easier then I thought. Jacked car up and put on axle stands(I like the stance lol). Used a long, sqaure shafted screw driver and pried the lock ring ccw loose, worked like a charm.
Repop. In good shape, but float took on fuel, so a pinhole somewhere. That was more than likely from me hitting it as it ohmd out pretty close to specs I've seen on here. The float arm felt like it was hitting detents in a places? Once I opened it up I saw where the wrappings had spread and were the "detents". I decided to use a spare repop I had. Checked float, no leaks. Float arm went smooth with no "detents" and ohms were pretty close to spec, 10.0-75.0
Lock ring appears repop, that could be why it was easy to remove?
Gasket wasnt bad, but was showing some wear so put in a repop lock ring gasket set. Hope it's a non issue!
Trying to install the spare repop is a pain! I've tried several different ways to try and weasel in with no go. Tomorrow I'll drop the tank some and see if that helps. I've already drained the tank.
Oh ya, I noticed the sender I removed had a set screw that was to adjust the length/height if float arm.
