My Proposal – Technical Regulations – Chapter 6 and 7

ARTICLE 6: FUEL SYSTEM

1. Fuel tanks
   If the engine requires a fuel tank, whether in solid, liquid or gas state, it has to be all stored in a unique tank which is able to sustain any crash as simulated during the crash tests.
   It has to be located in the rear section of the car, in the engine van between the safety cell and the rear wing.
2. Fittings and piping
   1. Any aperture be closed with a fitting, secured with a single threaded fastener on the full diameter of the opening, provided that this threaded fastener is provided with mechanical secondary locking.
      All other apertures in the fuel bladder must be closed by hatches or fittings which must:
      1. Be secured to metallic bolt rings bonded to the inside of the bladder.
      2. Have bolt hole edges no less than 5mm from the edge of the bolt ring, hatch, or fitting.
      3. Attach directly to the fuel bladder and have no part of the survival cell structure included in the closure.
      4. Be secured with multiple fasteners in such a way that the absence of any single fastener does not compromise the security of the closure.
         
   2. Where the tank is attached to the survival cell, fixings must be designed so that if it is pulled away from the survival cell, the attachment will fail without compromising the integrity of the fuel bladder.
   3. All fuel lines between the fuel tank and the engine must have a self-sealing breakaway valve. This valve must separate at less than 50% of the load required to break the fuel line fitting or to pull it out of the fuel tank.
   4. No lines containing fuel may pass through the cockpit.
   5. All lines must be fitted in such a way that any leakage cannot result in the accumulation of fuel in the cockpit.
      
3. Fuel tank fillers
   Fuel tank fillers must not protrude beyond the bodywork. Any breather pipe connecting the fuel tank to the atmosphere must be designed to avoid liquid leakage when the car is running All fuel tank fillers and breathers must be designed to ensure an efficient locking action which reduces the risk of an accidental opening following a crash impact or incomplete locking after refuelling.
   The cover and its attachments must be sufficiently strong to avoid accidental opening in the event of an accident.
   
4. Refuelling
   1. Tanks should contain enough fuel for the duration of the whole race, regardless od the type of the engine.
      If the engine is electric, the charging duration of the batteries should cover the length of the whole race
   2. Fuel may not be added to nor removed from a car during a race
   3. During other sessions of the Competition, refuelling is allowed only inside the garage.
      
5. Fuel draining and sampling
   1. Competitors must provide a means of removing all fuel from the car.
   2. Competitors must ensure that a 1.0 litre sample of fuel may be taken from the car at any time during the Competition.
      After a practice session, if a car has not been driven back to the pits under its own power, it will be required to supply the above mentioned sample plus the amount of fuel that would have been consumed to drive back to the pits. The additional amount of fuel will be determined by the FIA.
   3. All cars must be fitted with a system in order to facilitate fuel sampling.
   4. The sampling procedure must not necessitate starting the engine or the removal of bodywork (other than the nosebox assembly and the cover over any refuelling connector).

ARTICLE 7: OIL AND COOLANT SYSTEMS AND CHARGE AIR COOLING

1. Location of lubricating oil tanks
   All oil storage tanks, if needed, must be no further outboard than the lateral extremities of the survival cell.
   
2. Oil and coolant lines
   1. No lines containing coolant or lubricating oil may pass through the cockpit.
   2. All lines must be fitted in such a way that any leakage cannot result in the accumulation of fluid in the cockpit.
   3. No hydraulic fluid lines may have removable connectors inside the cockpit.
   4. Heat exchangers, if needed, should be located in the engine van in the rear section of the car.
