I don’t see a question, but it’s not hard.
Support the tank with a block on top of your jack and loosen the strap bolts so it drops on the jack.
Then lower your jack a little and you will have Access to the tunnel if that is what’s needed.
If you want to fully remove it, then obviously you remove fuel lines and drop it.
I would drain the tank to do it too. You can get a tune revision that makes the fuel pump run in accessory mode. Be careful, it will fill a 5 gal gas can quicker than your think. Don't ask me how I know that.
I have a TP50 from SnapOn. Lisle now has one available too (for much less $ than SnapOn, obviously). You definitely do not want to use the standard T50 on the gas tank bolts.
