I think according to legend you can get to it without removing the fuel tank - you just have to have rubber arms - if your's still has the pretty fiberglass cover over the lines running into the back of the livewells remove it and see what you can see. I've had one go bad and finally just took it to the dealer and pretty sure they removed the tank to get to it. Did replace one pump cartridge and that was hard enough since you could only see the top of the pump. Love my legend 211 but trying to work on pumps etc is a real pain with that fuel tank in the way - only complaint I've ever had with the boat.
Back then Fish and Ski Marine in Sanger was a dealer and they did it for me - they aren't legend dealers anymore but could probably do it if you can't get to it yourself or don't want to try to pull fuel tank.
so I pulled the cover off
I can touch the pump and believe i can probably finagle the quick disconnect lines off the top and front..
the rear is under the tank and may be able to get it off but getting everything back in and new cable is gonna be tough
