I haven't seen it yet, so I'll reiterate this point: NEVER WORK ON A PRESSURIZED SYSTEM.

Tightening brass fittings in a pressurized plastic tank has a higher probability of causing cracks, which ultimately leads to a rupture.

I don't know the details of the GTR tank rupture, but all of the evidence in past explosions points to user error, not a design flaw.
