Creating a fuel delivery system for a fighter jet is a tricky process, as the whole body is regularly subjected to intense force. That means the system can’t be too complicated, or it would only take a small jostle to throw the entire system out of whack. This is probably why the developers of the Eurofighter Typhoon decided to opt for a simple, streamlined means of fuel delivery.
The Typhoon utilizes a series of flexible couplings designed to swiftly and simply deliver the fuel through the main fuselages and wings. This makes it easier to connect and maintain the fuel tanks, which in turn all have matching fuel-flow proportions. The design also gives the entire jet a uniform center of gravity which, alongside a series of strategically-placed relief valves, helps to maintain the system’s air and fuel pressure levels. The combined fuel tank can hold a maximum of 16,755 pounds (just over 8 tons), which is managed by an onboard computer system. Basically, this helps deliver fuel efficiently, allowing the jet to fly long distances without burning up its entire tank. Overall, this fuel can carry the jet 1,800 miles before it needs a refuel.
