Self-sealing fuel tanks don't usually use pressurized injection. They simply have layers of material around the container that swells when exposed to fuel. There is a bladder inside that prevents contact under normal conditions. When punctured, the fuel wets the material, which swells the material and seals the leak.

It's remarkable to me that this car is secured against rifle rounds. It takes serious armor to protect against rifle rounds. To give some perspective on the difference between a rifle round and a typical hand gun round, here are a couple of groups of guns:
Typical law enforcement sidearm rounds: 9mm - 470 joules .40 S&W - 576 joules .45 ACP - 540 joules Military assault rifles: 7.62x39mm (AK-47) - 2,070 joules 5.56x45mm (AR-15) - 1,796 joules 7.72x54mm (.308 Remington) - 3,799 The AK-47 (and the AR-15 for that matter) is relatively weak for a rifle (when compared to hunting rifles, for example), but it's still roughly twice as powerful than the majority of hand guns people carry around. Just for fun (and perspective), here's the energy for some not-so-typical firearms. Powerful handgun rounds: .357 magnum - 750 joules .44 magnum - 1,400 joules .50 AE (the round fired by the Desert Eagle) - 2,000 joules Ridiculous handguns that most people own just for novelty, or because they need to kill a bear. All of these are fired from large revolvers that you wouldn't want to strap to carry around. .454 Casull - 2,600 joules .460 S&W - 3,300 joules .500 S&W - 3,500 joules Monster rifle rounds that the military uses for "anti-material" purposes. Basically, these are powerful enough to detonated unexploded ordinance. .700 Nitro Express (featured in a lot of "LOL they dropped the rifle" videos) - 12,000 joules .50 BMG (commonly referred to as the fifty-cal) - 15,037 14.5x114mm (Russian "equivalent" [in purpose anyway] to the .50 BMG) - 32,000
