Given the tank was an HP100 steel, I'm not to worried about the fill the OP received. Heck, a set of HP100 doubles I dove two weeks ago in Florida from Fill Express were at 3800psi. Thanks Didier!!!!
My real concern here is the tank is a rental and the attitude of the rental operator. If they are treating their tanks like this, what does the rest of their rental fleet look like? Not paying attention to a tank while filling could indicate other "inattentive" issues with that operator's gear. Given it was a yoke connection and the fact it sat out in the sun under pressure is not surprising the o-ring blew. Heck, I have seen yoke o-rings blow under normal pressure while the rig was being moved around on dive boats. That's why DIN is a much better system of connection. B.
