Gator 620i Fuel Leak - which part?

I have a fuel leak around the top of my fuel tank (Gator 620i). Looking at the blowup drawing (John Deere Parts catalog) of the tank it says the fuel gauge is part 23 and the bushing is part 24. Going down the list to the actual part number the list shows two items for part 23 - a fuel sender (AM143171) and a fuel gauge (TCU24946) and two parts for part 24 - a bushing (M149648) and another bushing (TCU22449). I don't really want to buy all four parts as I think it is just the bushing. Anyone out there know which bushing I should get???

Anyone replace one of these bushings? Do you just yank/pry it out?
