On my '05 990, the grey tank is narrow and long and on the left side. Runs from the front to the start of the rear overhang. Probably more than 7 feet long. The sensor wires are located all the way forward on the front end of the tank.
I have the dimensions somewhere but yours has a sliding tray so will be different.
I think you'll need to remove the bottom cover to get easy access. It's not that difficult, but you'll be on your back and have to dig out the sealer on the screws.
It will give you good insight into how everything is put together. I found one of the tank support frame screws running through the wire from the generator to the transfer switch, some broken screws, and some cracked support frames. Luckily it wasn't shorting the AC power. (The TC was used when I bought it so not sure how it got that way) I repaired everything and added insulation. Then resealed the bottom cover and screws with flexseal.
You may want to add some extra insulation when you have it off. I added one cross member also, to help support the bottom center of the fresh water tank. The black and grey tanks didn't need more support.
