3.2. GROUPS T1A et T1B

3.2.1. Fuel lines and lubricating oil must have a minimum burst pressure of 70 bar (1000 psi) and a minimum operating temperature of 135 ° C (250 ° F).

when  they are flexible, these lines must have threaded connectors and an outer braid resistant to abrasion and flame (do not sustain combustion).

In the case of fuel lines, the metal parts are isolated from the shell of the car parts / non-conducting parts , must be electrically connected.

 


3.2.2. lines containing hydraulic fluid, with the exception of lines under gravity alone, must have a minimum burst pressure of 70 bar (1000 psi) or more depending on the operating pressure, and a minimum operating temperature of 232 ° C ( 450 ° F).

If they are flexible, these lines must have threaded connectors and an outer braid resistant to abrasion and flame (do not sustain combustion).

 


3.2.3. lines  for cooling water or lubricating oil must be outside the cockpit. Fuel lines and hydraulic fluid may pass through the cockpit, but without presenting any connectors except the front and rear bulkheads in accordance  with the  drawings 253-59 and 253-60, and the braking system.

Only the supply of hydraulic fluid and the master cylinder brake will be accepted in the interior.

 


3.2.4. Pumps and fuel valves must be outside the cockpit

 

3.2.5. Only the intake , exits and lines for air  ventilation of the interior are allowed inside  cockpit.

 


3.2.6.The electrical cables must be protected by coverings which do not sustain combustion.

All fuel pumps must only be operated when the engine is running or during startup.



FUEL TANK

CAUTION: a validity of 5 years they can be approved  by the manufacturer for a period of 2 additional years

IMPORTANT IF YOU CHOOSE TO T2 ASSEMBLY FOR THE TANK OR FT3 FT5 ALL THE FUEL SYSTEM MUST BE MUST CONFORM TO THE TYPE AVIATION ARTICLES 3.2 AND 283 285.1.2


important for setting the tank vents origins or FT3, FT5 it should be out on the roof of the car or make a loop as high as possible insinde the car and come  under the car on the opposite side connecting the tank to put these free air must be equipped with self sealing when said valves no-return valves

ARTICLE 14 FUEL TANK  APPROVED BY THE FIA
When a competitor uses a safety tank, it must come from a manufacturer approved by the FIA. To obtain the approval of the FIA, the manufacturer must have demonstrated consistent quality of its product and its compliance with the specifications approved by the FIA.

The tank manufacturers recognized by the FIA ??undertake to deliver to their customers exclusively tanks complying with approved standards. To this end, on each tank delivered shall be printed the name of the manufacturer, the exact specifications according to which the tank was manufactured and the date of manufacture.



INSTALLATION OF TANKS

The tank can be replaced by a safety tank homologated by the FIA ??(specification FT3), or other approved by the manufacturer of the car. In this case, the opening left by the removal of the original tank may be closed by a panel.

The number of tanks is free.

You can also combine different approved tanks (including the standard tank) and FT3.

Any container not approved to be an FT3. The competitor must submit the certificate of compliance or approval of FIA which include the tank number and year of manufacture.

Collecting tanks with a capacity less than 1 liter are free construction. Their number is limited to the main tanks fitted to the car.

The original tank may be retained but in its original position (t2, T2B and T2B+). FT3 a larger capacity can be mounted at the location of the original tank.

For cars that the manufacturer has provided a closed space for luggage (trunk forward or backward), an integral part of the body, this property should be used to accommodate the extra tank. Of holes must be provided in the floor of the case to permit the flow of fuel in the event of leakage. For cars with the manufacturer did not provide any specific location for luggage, forming part of the body, the additional tank may be located inside the passenger compartment behind the rearmost seat.
For the position of the tank in the car T1Aet T1B refer to the Technical Regulations T1. SEE BELOW

In all cases, the tank, including the fill pipe must be completely insulated with non-combustible walls and sealed to prevent any leakage of fuel in the cockpit or contact with the exhaust pipe. In case the tank is installed in the luggage compartment and rear seats removed, a fireproof wall and waterproof flame and liquids will separate the interior of the tank. In the case of cars with two volumes, it is possible to use a non-structural wall of transparent and non-flammable plastic between the cockpit and the location of the tank. Tanks must be protected effectively and securely attached to the bodyshell or chassis of the car.

The location and size of the filler opening and the closure cap can be changed provided that the new installation does not protrude from the body and present any collateral against a fuel leak to an interior compartments of the car. These holes may be located in the locations of the rear windows.

The filler and vent free should always be located outside the cockpit on a metal part. If a fill port is located within the body, it must be surrounded by a discharge vessel with outwardly.

Setting the air vent must be out on the roof of the car, or to loop as high as possible inside out under the car to the side opposite its connection to the reservoir. These vents have to be equipped with free self-sealing valves.

For Pick-up type cars involved in T2,T2B or T2+, and whose interior is completely separated from the rear tray (metal cabin fully closed), the tank will be required to come from a car manufactured in series or be a reservoir of FT3 safety guy and tray must be fitted to allow the flow of fuel in case of leakage.

 

          
   Tank Installation: EN T1A ET T1B  ( YOU CAN SEE ARTICLE 283.14)
2.2. Tanks: (See also article 283.14) Any tank containing oil or fuel, must be located in the main structure of the car.

2.2.1. Only the fuel tanks conforming to the FIA/FT3, FT3.5, FT5 standard are permitted
.
2.2.2. Tank installation: The tank (s) will be installed (s) preferably outside the cockpit. If a tank is installed in the cockpit, it will be located in an area at least 15 cm inside the structure. It must be isolated by a fireproof and liquid-proof bulkhead. For any new construction from 1st July 2014, and only for cars competing in an open-road event (rally) the fuel tank must be situated behind the front seats.
