Found this article that examines the reality of "blowing up a fuel tank" It mainly addresses the fictional/special effects automobile gas tank explosions, but further down the article, jet fuel and aviation fuel (Avgas) is also discussed.

excerpt:
In fiction, shooting a fuel tank makes it explode. This myth was busted by MythBusters as [video=youtube;w4n--xOOoWE]http://www.youtube.com/watch?v=w4n--xOOoWE[/video] that in most cases it simply will not work. A real life fuel tank explosion was only possible when they used a minigun armed with incendiary rounds which, suffice to say, is generally unlikely.
excerpt:
Diesel pretty much won't blow at all unless you light a fire under it and keep it burning until it causes a BLEVE (Boiling Liquid Expanding Vapor Explosion), which will take a while to accomplish. Jet fuel's extremely-high ignition temperature causes it to behave a lot like diesel.
Avgas (aviation gasoline, the super-high-octane blend used in piston-engined aircraft) can blow up like this (with a very Hollywoodish fireball), which is why airplanes since the 1920s have things like self-sealing fuel tanks and inert-gas-pressurization for their tanks.
...and this. . .
It is important to note that, while conventional bullets or even tracer bullets do not often generate the heat or have enough surface area to diffuse this heat fast enough required to ignite fuels like diesel or jet fuel, white phosphorus rounds, like those shot from the Lahti L-39 Finnish 20mm Anti-tank/Anti-aircraft sniper rifle (more commonly known as the "Elephant Gun") or the minigun wielded by the Mythbusters, are more than capable of both penetrating the outer shell and fuel-tank wall of the vehicle they are hitting and delivering enough heat to cause an explosion.
MOO
Not sure of the specific blend of fuel in the targeted tanks, or if SP had an "elephant gun" or "minigun" available in the room.
