Relevant info:
But after the car was recovered to the pit lane, the FIA were unable to extract the stipulated one-litre fuel sample from the C43 machine, leading to Bottas being disqualified from proceedings – although the stewards have ruled that the two-time Silverstone pole-sitter can start the race in P20.

Does this mean the reason he had to pull out in the first place was because he ran out of fuel?
It had to be. There was almost nothing left in the car. I get the feeling the FIA wil be testing the car frequently for underfueling now. Looks a bit dodgy for Alfa
Technically this breaks the rules by stating Bottas’ position, but I honestly can’t think of a reasonable way of phrasing it that wouldn’t make this obvious anyway.
