Just as a head up to others, You don't need to remove the tank to do all this, and in fact it provides support and a decent work height
You can use a decent bit of Flat bar steel or hardwood and a hammer to bump the lock ring off
Just do the top part first to syphon down below the fuel Pump flange before you undo the pump flange
Sorry Biker Math Not meaning to Piss on your fire, You did well you got the Job done so fair play but you probably watched an American Video before you started?
They would have you remove the feckin final drive before you remove the tank!!
