FIA FUEL TANK CAPACITY MEASUREMENT
Here is the method for measuring the volume of your fuel tank, practiced by the FIA. We invite you
to perform this procedure every 6 months.
Any other measure is considered inadmissible
The method for checking the total capacity of the WRC fuel tank is as follows:
1) The competitor will supply the material, tools and extinguishers needed.
2) Fuel tank must be fitted with its leakproof box (see article 255A) on the WRC car.
3) The WRC car to be checked will be located on a flat surface.
4) The fuel supply outlet for the engine will be disconnected and a leakproof cap will be fitted on the fuel
tank.
5) The fuel return into the tank will be disconnected and a leakproof cap will be fitted on the fuel tank.
6) The breather in conformity with Article 253 of Appendix J will be disconnected and a leakproof cap will
be fitted on the fuel tank.
7) The petrol gauges will remain fitted on the fuel tank.
8) The fuel tank must be filled completely (using the two quick‐action couplings for refuelling as specified
in the Homologation Regulations for WRC kit‐variant).
9) By means of the FIA sampling connector, all the fuel taken on board and available by this method will be
taken out, measured and accounted for.
10) After a complete withdrawal of the fuel by the methods given above, if fuel is still found in the low
pressure pumps, internal fuel lines, etc. and the depths of the tank, it will be taken out by dismantling
and stocked. It will be accounted for. All these actions, emptying and transfers will be made by the
competitor’s mechanics under the orders of the Technical Delegate.
11) The amounts of the various quantities of fuel taken out according to this method will be added together
to obtain the total capacity of the fuel tank. The maximum tolerance will be 0.50 per 1000 on the quantity
of fuel taken out and there will be no corrections for temperature and/or density.
12) After the final measurement of the amount taken out, the competitor, while present during these
checks, will acknowledge that all the fuel has been taken out by signing the final measurement sheet.
13) In the event of contestation or appeal, if it is decided to repeat the measurement at once, the
replacement of all parts removed must be made by the competitor.
