I didn't have much success with pictures but what I see on this top view of the tank makes it look like the rigid black nylon hose from the center to the canister may be removable...
It looks like a formed rubber hose, but I just can't remember there being one there. I've had dozens of tanks out and chased evap leak codes for years but when something doesn't give me problems I don't always take notice lol! Here's a rather poor underside view of the line at the canister...
If the yellowed area is what was cracked or broken, it does seem like it could be repaired with a little creative hose work. All that matters is that you maintain most of the inner hose diameter and that the system has no external leaks... pretty much anything goes.
The hose on the far left in this pic is the one I'd wondered about earlier and seems to crack only up near the steel line.
To drop the tank, do what you can to run some gas out first. It's not a hard unit to work with, but gas adds "live weight" to the thing, something that can get away from you at times when it sloshes.
I use motorcycle tie downs to support the tank when the tie straps are removed. If you can string a single tie through the center of the tank in a north-south direction, it will give you quite a bit of room to lower without it being able to get away and fall out because it tips and contacts the bottom of the car.
Take your fuel line and pump connector off first so they don't get stretched.
Going back up is handy with the motorcycle tie down as well... just push up with one arm, pull the strap with the other to hold it in place while you get the straps back on. The straps hinge at the forward part of the tank and unbolt near the axle.
