my sending unit is no good, it was bouncing from e- 3/4 tank while not moving then I tried checking for a good connection and I fixed it so good it just stays on e my question is do i have to pull up the center floor section to pull it out? I have an access hole but it is off to the side of access. Is there anything I need to do ,other then remove screws, when pulling it and reinstalling it?

the floor section

I have never had mine up. I can reach mine leaning into the bilge. I would try that.

I would try to reach it from the bilge if you can.

You can get it out without removing the floor... Just remove the screws and pull it out. If you have a 242 SS you may have to pull the floor panel but the LS will come out with everything in place!

I pulled the floor it was easy I just didn't know if I would be opening a can of worms
