ARTICLE 6 : FUEL SYSTEM
6.1 Fuel tanks :
6.1.1 The fuel tank must be a single rubber bladder conforming to or exceeding the specifications of FIA/FT5-
1999, the fitting of foam within the tank however is not mandatory. A list of approved materials may be
found in the Appendix to these regulations.
6.1.2 All the fuel stored on board the car must be situated between the front face of the engine and the driver's
back when viewed in lateral projection. When establishing the front face of the engine, no parts of the fuel,
oil, water or electrical systems will be considered.
Furthermore, no fuel can be stored more than 300mm forward of the highest point at which the driver's
back makes contact with his seat. However, a maximum of 2 litres of fuel may be kept outside the survival
cell, but only that which is necessary for the normal running of the engine.
6.1.3 Fuel must not be stored more than 400mm from the longitudinal axis of the car.
6.1.4 All rubber bladders must be made by manufacturers recognised by the FIA. In order to obtain the
agreement of the FIA, the manufacturer must prove the compliance of his product with the specifications
approved by the FIA. These manufacturers must undertake to deliver to their customers exclusively tanks
complying to the approved standards.
