Looks like someone has been in there before, I'm sure the fuel sender don't come from factory with silicone on the wires, and I've seen a lot of senders. The wiring should be kept high as possible to keep any connections dry. Looks like you are doing ok so far and it does look like the screws you pointed out need to be removed to access the area. A pic a little farther away would give us some perspective of the area also. While you are in there, check all the fuel hoses for weather checking, and see if that sender was leaking for some reason in the past. If it was, replace it. If the deck goes under the helm area to far, it may have to be removed also, been there in the past, hope yours just is slightly slid in there.Good luck!
