That little nut on the bottom of the sender has something like a tight fitting little "round" of plastic tubing surrounding it. I just preyed if off, undid the nut, fixed the sender and used thread lock on the nut when reassembling.

Come to think of it I think I did finally get the nut off, because I did eventually get it apart, just been so long I forgot. My memory is not what it use to be to say the least.

I figured if I started prying that little plastic tubing off, that would be the end of the sending unit but I could bring the unit into the shop tomorrow and attempt it.

I got into one where the little wire was broken at the bottom. A friend held it and I soldered it back together. I tucked it away for a spare and didn't try it, but I think its fixed

I seem to remember that the fuel sending light getting brighter was a sympton of another problem on a shared circuit. If you have a electrical diagram look and see if it shares a circuit and if it does share with say another gage or warning light the other part of the circuit is the problem.

I've tried to remove a fuel level sending unit from a 300D with channel locks before with no success. There isn't a lot of room.

Is there another method or tool that can be used?

Channel lock is the tool I used. It was a tight space, but it worked well for me.

I went to a friends shop and borrowed a socket & ratchet that fit the thing. Someone had PMed me the idea & size. Due to length of time since then I don't remember who or the size the of the socket. Later on for future removel I was able to use my channel locks.
