EMERGENCY REPAIRS TO TANK ENVELOPE.
There are two ways to repair the tank
envelope.
Wood plugs should be used during emergency tank repairs to stop
fuel leaks until a sealing clamp can be installed. Plug replacement may not
be possible until the fuel height and internal pressure have been reduced.
Plugs can be used for tears up to 1 1/2 inches (3.8 cm). Sealing clamps can
be used for tears up to 6 inches (15.2 cm).
