Shooting a fuel tank is a common trope in fiction, especially in video games and action movies, where it is often depicted as causing an explosion. However, in reality, this is largely a myth, as fuel tanks are designed with safety features to prevent leaks and explosions, even when subjected to significant trauma like gunfire. Modern car fuel tanks, for example, have reinforced materials, anti-leak structures, and pressure release systems. While explosions from shooting fuel tanks are rare, it is still dangerous and can cause fuel leaks, fires, and other hazardous situations, especially if there are additional factors such as the presence of incendiary rounds or a nearby fire source.

In video games, shooting fuel tanks can immobilise enemies
In video games, shooting fuel tanks is often a go-to tactic to immobilise enemies. While in reality, shooting a fuel tank will not make it explode, video games have popularised this trope for dramatic effect. This is especially true in games where the fuel tanks contain nitro, in addition to gas, or in cases where there is something in the vehicle that can spark and blow up the fuel tank.
In the video game From the Depths, for example, shooting a fuel tank will cause an explosion, but the primary advantage of attacking the tank is to cause the enemy to run out of fuel and lose power. Similarly, in Grand Theft Auto: San Andreas, shooting the gas cap on a car will cause it to explode, but this is a rare occurrence in the game. In most cases, shooting the fuel tank will only cause flames to shoot out, as seen in Lethal Enforcers 1. In Mafia II, however, shooting the fuel caps causes cars to explode reliably after two shots with any weapon.
The Red Alert series of games also features explosive fuel barrels conveniently placed next to key targets. The second game in the Tiberian series features less-explosive ammo crates. The Far Cry series of games has this as a gameplay element, usually to showcase dynamic fire effects. Some of the tanks don't immediately explode when shot; instead, they emit gouts of flame from the bullet holes or fly around like rockets before exploding.
In World of Tanks, shooting another tank's fuel tank won't make it explode unless the weapon used is powerful enough to kill the tank. However, if the tank survives, it will be immobilised until its crew can fix it. Shooting fuel tanks is also a viable tactic in both Mass Effect games. In the first game, there are little plasma, ion, and cryo tanks all over different battlefields, and occasionally, a big one with fuel in it. In the second game, shooting the fuel tank with a lower-damage weapon will light it up, and it will explode. Using a high-powered weapon like a sniper rifle will cause it to explode immediately.
In some games, shooting fuel tanks is a way to refuel the player's vehicle. In the 1982 game Zaxxon, the player must fly through an enemy fortress with a diminishing fuel supply, and they can refuel by shooting fuel tanks.

In films, shooting fuel tanks is a special effect
To create a fuel tank explosion in films, special effects are employed, and the tanks are often filled with nitro in addition to gas. The use of “tracer or incendiary" ammunition, which contains pyrotechnic charge, can also increase the chances of an explosion. However, in reality, modern automotive fuel tanks are designed with safety features, such as reinforced materials, anti-leak structures, and pressure release systems, making them resistant to leaks and explosions, even when subjected to gunfire.
In some cases, shooting a fuel tank can result in a fuel leak, which can still be dangerous and potentially lead to an explosion if there is an ignition source nearby. This was demonstrated in the film Terminator 2, where shooting the fuel tank caused a leak, and a flare was then used to ignite the fuel. Additionally, in certain video games, such as Grand Theft Auto: San Andreas, shooting the gas cap is depicted as causing an instant detonation of the vehicle, further perpetuating the "Shoot the Fuel Tank" trope.
While the on-screen portrayal of shooting fuel tanks may not align with reality, it remains a popular cinematic device, contributing to dramatic action sequences and heightening the sense of danger in battle scenes.

In reality, shooting fuel tanks rarely causes explosions
For an explosion to occur, three essential elements are required: an oxidizing agent, heat, and fuel. While fuel is obviously present in a fuel tank, the other two elements are typically not present in sufficient quantities to cause an explosion. The amount of oxygen in a fuel tank is usually too low to support an explosion, and the heat generated by a bullet is often insufficient to raise the temperature of the fuel to its ignition point.
In a 2004 episode of the TV show MythBusters, the team tested this theory by shooting a gasoline tank with five bullets. The tank did not explode or even catch fire. They concluded that standard bullets were unlikely to cause an explosion, even when fired from a distance that would allow the bullets to ignite with air friction. However, they noted that tracer rounds or incendiary rounds, which are designed to create intense heat upon impact, could potentially ignite the gasoline and cause an explosion.
It is worth noting that while explosions are rare, shooting a fuel tank can still have dangerous consequences. It can cause fuel leaks, fires, and other hazardous situations. Additionally, in certain circumstances, such as with larger storage tanks or aircraft fuel tanks, there may be a higher risk of an explosion due to the increased volume of fuel and other factors.
Overall, while shooting a fuel tank may not result in a dramatic explosion as often depicted in fiction, it is still highly dangerous and discouraged due to the potential for other hazardous outcomes.

Fire departments shoot acetylene tanks to prevent explosions
Shooting a fuel tank is a common trope in movies and video games, where it is often depicted as causing an explosion. In reality, however, this is not always the case. For example, during World War I, England tried shooting down German hydrogen airships with standard bullets, but this did not ignite the hydrogen. Only when they used tracer bullets with phosphor were they able to ignite the gas and destroy the airships.
Similarly, the TV show MythBusters tested whether shooting a gasoline tank would cause it to explode and found that it did not. They explained that the fuel inside the tank did not reach the necessary ignition temperature.
In some cases, shooting a fuel tank can actually be a safety measure. For instance, in the video game Gears of War, the player can shoot propane tanks to light paths and clear areas of enemies. This tactic can also be used by fire departments to prevent acetylene tanks from exploding. By carefully shooting the tanks, firefighters can release the built-up pressure and prevent a potentially catastrophic blast.
While shooting a fuel tank may not always result in an explosion, it can still be a dangerous and destructive act. The fuel inside the tank can leak out and ignite, causing a fire. Additionally, the tank itself can be damaged or destroyed, releasing its contents and creating a hazardous situation. Therefore, while it may not always live up to its explosive depiction in popular culture, shooting a fuel tank is still a risky and potentially deadly proposition.

Military aircraft use inert gas to prevent explosions
Shooting a fuel tank is a popular trope in fiction, where it is often depicted as causing an explosion. However, in reality, shooting a fuel tank may not always result in an explosion.
Military aircraft use inerting systems to prevent explosions by reducing the oxygen content within the fuel tank to around 9%, which is lower than the normal atmospheric oxygen content of 21%. Inerting systems work by ventilating fuel-vapour-laden ullage gas out of the tank and into the atmosphere. The goal is to create an inert atmosphere within the fuel tank that will not support combustion.
Nitrogen is commonly used in inerting systems due to its availability and low cost. It is generated during flight using a membrane that allows nitrogen atoms to pass more easily than oxygen, resulting in a gas with only about 12% oxygen, which is low enough to prevent an explosion. Other gases such as argon have also been considered, but their rarity makes them more expensive and less practical.
The use of inerting systems in military aircraft has been standard practice for several decades, with early applications dating back to the 1940s. Civilian aircraft have also adopted inerting systems following incidents such as the TWA Flight 800 crash in 1996, which was caused by a fuel tank explosion. The Federal Aviation Administration (FAA) has since mandated the use of inerting systems in commercial jets and is continuously working to improve their effectiveness.
In conclusion, military aircraft utilize inert gas systems to prevent explosions by reducing the oxygen content within fuel tanks. This technology has been crucial in enhancing the safety of military and civilian aircraft, reducing the risk of fuel tank explosions, and protecting both passengers and crew.

Frequently asked questions
In movies, we often see a fuel tank exploding after being shot at. However, in reality, this is a myth. Modern fuel tanks are designed with safety features to prevent leaks and explosions. For an explosion to occur, you need a precise mixture of fuel vapour and air, along with a potent ignition source, which is not typically met in everyday scenarios.
There are very few documented cases of fuel tanks exploding due to gunfire. In most cases, it does not lead to an explosion. However, in certain video games like Modern Warfare and its sequel, it will take several rounds to explode a fuel tank. In the TV show MythBusters, the team was able to ignite gasoline with tracer rounds from a great distance, but the tank did not explode.
Shooting a fuel tank can cause fuel leaks, fires, and other hazardous situations. It can also immobilize vehicles that run on fuel. In certain situations, shooting at a fuel tank can be a viable tactic to deal with potential explosions, as it releases gas in a semi-controlled manner, which can then be burned off.
