Subject: [PATCH] Added ability to rig fueltanks

To make your very own ghetto explosive:
1.Wrench faucet open on tank.
2.Add assembly of your choice (only timers and radios work as triggers here)
To unmake it simply remove assembly with hands and wrench faucet back.

Rigging tank with igniter logs for admins.

Also explosion size depends on amount of fuel left in tank.
