I know the rules, but it's not banned to have fuel line, you also need to have some control over the flow e.g. the control valve and you need also fuel pump. It's legal like DAS is. There is no rule that ban flexible fuel line and there is no restriction (new one is on the way - 2dl) how much fuel can be in the fuel line.PlatinumZealot wrote: ↑Wed Mar 04, 2020 4:37 pmAccumulation of fuel is explicitly banned. This would be slam dunk disqualification so you are suggesting that the accumulation device is there but it is disguised or cannot be easily checked when the car is at a stand still.
In this case it would be that FIA cannot prove that it is there. Otherwise it would be a slam-dunk DQ again.
For fuel accumulation they could use Memory Metal.
The other way of cheating the flow meter is using a variable property fuel.
What piqued my interest in the letter is the mention of "Alternative Fuels."
Was Ferrari using a sort of fuel that changes density? or a type of fuel that changes its composition? Hmm.. this could explain why less fuel was left in the tank than expected.
Ferrari will say "We have fuel pump with fixed flow (not exceeding the allowed amount) therefore we need controlling the amount of fuel for ICE with flow valve. To prevent the fuel line to fail/burst we have expendable fuel line."
