Lots. You should inert the tank first. Hopefully it's empty to start, completely drained. Then you can simply drop in some dry ice which will fill it with Co2. That displaces all the oxygen and without O2, no fire or explosion can happen. You can also use exhaust fumes to displace the oxygen, or better yet, remove the sending unit and install the pickup through the top plate of the unit.
