7. A Fuel Tank must not be fouled by moving parts of the vehicle, or mounted so that it is likely to be subject to abrasion by adjacent parts.

8. Fuel Tanks must not be positioned near a heat source

9. Fuel Tanks must be positioned so as not to be vulnerable to damage from protruding parts or sharp edges in the event of a front or rear impact.

10. The fuel tank must be positioned so that in the event of a leak the fuel could not accumulate or find a path to the passenger compartment. (if fitted in a compartment there must be a drain which does not exit onto a heat source)

11. A Fuel Tank must not be located in, or form part of the passenger compartment, or other compartment integral with it and the bulkhead that separate the passengers from the fuel tank must be free from holes through which any escaped fuel could travel.

12. The fuel tank must be fitted with a vent (to permit release of a pressure build up) which does not exit on to the exhaust or into the vehicle or be situated at such a height that fuel would be likely to leak when the vehicle is driven.

13. Any fuel filler neck or vent must not allow spilt fuel to be able to fall onto the exhaust system.

14. Fuel tank filling points must not be located in the passenger compartment, luggage compartment or within an engine compartment.
