and at this point is there any point trying to fight the fire ?
Doubt it would flash back to the tank - too much petrol vapour - not enough oxygen - a full tank is safer than an empty one!
Some racing cars used to use a mesh in the tank which would stop the tank catching fire - it worked well and also had the advantage of acting as a big baffle but made refilling the tank a nightmare.
As to people using CO2 it is not suitable for anything in the open air and needs 10 times as much to replace Halon.
Personally I would stick with powder on show and my hidden green ones!!!
An electric and fuel shut off would also be essential.
