You should not need that much fuel for the race; if it rains for most of the race then you will probably only need about 210lts.
I am starting on the wet tyres with 67lts of fuel and I just left all the other fuel stops empty so every time I stop I will just refuel back up to 67lts.
True, i have gone for 220 for the whole race just to be safe in case it doesn rain for quite a few laps and the tyres end up getting destroyed before fuel runs out. Looking forward to see how it plays out.
