Disconnect fuel filler pipes (2. Large one with green clip and small one with orange clip). Squeeze the back of the clips and use pick tools
Disconnect breather tube (green clip)- use something small and strong to squeeze the back part and use pick tools to pull the rest of it out
Remove rear brace - Left side
-Remove the 14mm bolts on the left side before removing the 10mm bolts holding the plastic bc the plastic piece will get in the way and make it difficult to remove the 14mm bolts
Remove rear brace - Right side
-Remove the 10mm bolts holding the plastic to access the 2nd 14mm bolt for the brace
Remove the tank shield using 10mm sockets
Remove the fuel tank straps using 14mm sockets and a 10" ratchet extension
Lower tank out gently

Tips:
Put bolts back in the holes they belong to because otherwise it's hard to remember which bolts go where.
Put all your tools in a bin and drag the bin around with you when you get under the car
Add WD-40 to your bin of tools

Re-installation steps:
Use your whole body to maneuver the tank into place
Replace the tank straps with 14mm socket and 10" extension
Replace the tank shield with 10mm socket
Replace the rear brace - Put the bolts in loosely until they are all in place. Then tighten.
Reconnect the fuel filler pipes using dielectric grease to help
