What I also found interesting:
The regulations allow a maximum fuel flow of 100 kilograms per hour. However, there is a small margin for error. And Renault takes advantage of that.
The measuring device in the tank (Fuel Flow Meter) is exposed to certain resonances due to the movement of the racing car on the race track. Due to the vibrations and oscillations, the rules allow small outliers to move upwards. The maximum fuel flow rate may exceed 100 kilograms by three grams. That sounds like little, but it is obviously the decisive bit of room for manoeuvre in injection. "The increased flow rate is only effective for a very short time, then you have to be below it again," says Taffin. "Otherwise you won't reach 100 kilos on average."
