I just looked at the FIA website, there is a PDF of technical regulations for 2020 dated 04/30/2019 and a 0.25 liter restriction is already present. So FIA decided to close this "grey area" by itself or were there suspicions and requests from the teams in April?
Interesting.
So I have checked, what has changed between the sets of the Sporting and Technical Regulations between 04.30 and 12.04, which may be related to the discussion in this thread.
Here's what I have found:
Sporting regs:
In the PARC FERMÉ it is no longer allowed to do the following
h) Removal of the ERS energy storage devices which, once marked by the FIA technical delegate, may be retained overnight by the team.
i) The main electrical battery and radio batteries may be changed.
Technical regs:
6.1.2. When viewed in lateral projection, all the fuel stored on board the car must be situated between the forward-most of the two vertical planes referred to in Article 5.3.7 and 50mm forward of the line a-b-c in Drawing 2.
Added text in bold.
As noted in the thread on Ferrari PU there are changes to the test procedures for the fuels.
This is new text:
19.8.2 Fuel density will also be checked and must be within 0.25% of the figure noted during pre-approval analysis of the fuel that is declared to be in use .
19.8.3 Fuel samples taken during an Event will be checked for conformity by using a gas chromatographic technique, which will compare the sample taken with an a reference sample of the fuel that is declared to be in use. Samples which differ from the approved fuel in a manner consistent with evaporative loss, will be considered to conform. However, the FIA retains the right to subject the fuel sample to further testing at an FIA approved laboratory.
19.8.4 GC peak areas of the sample will be compared with those obtained from the reference fuel. Increases in any given peak area (relative to its adjacent peak areas) which are greater than 12%, or an absolute amount greater than 0.10% for compounds present at concentrations below 0.8%, will be deemed not to comply.
If a peak is detected in a fuel sample that was absent in the corresponding reference fuel, and its peak area represents more than 0.10% of the summed peak areas of the fuel, the fuel will be deemed not to comply.
If the deviations observed (above) by GC indicate that they are due to incidental mixing with another Formula One fuel to the one declared, but which has been approved by the FIA for use by the team, the fuel sample will be deemed to comply, provided that the adulterant fuel is present at no more than 10% in the sample. Any systematic abuse of mixed fuels will be deemed not to comply.
This is previous:
