No longer able to remove complete tanks from cars?

So do tanks get disassembled into metal sheets now? Whoops, there goes all my fuel. XD
Nope, on save scumming, everything seems to have worked fine. No idea what I did wrong. Might try again leaving the fuel in it.
[Edit edit]
My welder was out of charge. :unamused: So best delete this post.

Best leave the post so others can learn if they have the same issue.
