Luckily the hose fittings for the tank are exposed under the sink, so it's easy to access/service the hoses. But the tank is original, made of aluminum, and since I can see urine scaling around one of said fittings, I worry about other leaks that I *can't* see because they're behind the fiberglass. So for peace of mind, and because I can't get the disturbing image of a colander out of my head, the thing needs to come out. There's an article in the owner mods section that shows pictures of this job, but not the dimensions of the cut. I suppose I could eyeball it from these pictures, but I was hoping to remove a little of the guesswork. I seem to remember coming across a schematic of the tank with the Hunter logo on it and everything, but I'll be darned if I can find it now. I should've downloaded it when I had the chance! In the meantime, I'll keep poking around to see if other spaces can accommodate a fancy new Ronco tank.
