Aerator Removal-bass tracker 185

My livewell pump needs to be worked on/changed as well as my fill/drain valve. I didn't take a picture of it yet but it sits right above the bilge pump. Which is going to be extremely difficult to get to. I wouldn't mind taking out the gas tank to get access to work on it but the gas tank is not square and looks like the boat was built around it. Any words of wisdom to help me out here?

I can ask a better question with pictures later, but just hoping someone has been through this and knows what I should do.
