Fuel system and refuelling
The fuel tanks on Formula One cars comprise a single rubber bladder. These must be made of materials approved by the FIA and must be manufactured by certain approved companies.
The tank must be situated directly behind the driver and directly ahead of the engine. All fuel lines must be self-sealing in the event of an accident and no lines must pass through the cockpit.
The fuel tank must be encased within a crushable structure that forms part of the car's safety cell. This structure must be able to withstand very high impact loads as specified in the regulations.
The FIA may take a one-litre fuel sample from any car at any time during a Grand Prix meeting to check that the fuel being used is legal.
