Formula 1 car fuel buckeye filler hole slot difference (refuelling era and refuelling-ban era)

The F1 car fuel buckeye filler hole slot since the refuelling-ban era.

During the refuelling era, the F1 car fuel buckeye filler hole slot was larger due to larger fuel hose. But since the refuelling ban, the F1 car fuel buckeye filler hole slot was made multiple due to smaller fuel hose.

Your thoughts?

Yep, it's smaller. Why would that be? Hmmmm.

Is there not a reduced rate of flow for filling?

No need for rapid filling, would be my guess.
The interesting bit for me is the FIA connection….

The FIA connector will be for them to take their samples, presumably.

I assume the LH side, RH side ports are vents for filling. Unless the tank is actually split in two.
If you are more fortunate than others, build a larger table not a taller fence.

The other difference is in the refuelling era they had a buckeye on both sides of the car to accommodate different pit lane layouts.

Exactly my thoughts, I just wondered why they need a unique coupling for it and if so, how on earth did AM fall foul of the fuel sample test?

I guess it drops down to a specific pot in the tank designed to contain the fuel for sampling. But they had a leak of some sort and so used all of the fuel including the stuff in the "sample pot".

Since refuelling was banned, teams went back to smaller filler bulkheads. They can be smaller as the large spec refuelling port isnt required and refill times can be longer. Some are even smaller than the Toro Rosso one pictured (that's my picture by the way thanks for the credit).
The tank still has left and right filler ports, but only one is set up with the connectors, to correspond to the side of the of garage the fuel scales are positioned.
The left and right connectors are to drain the tank, as as the hybrid battery and safety data recorder tend to sit under the tank along the centre line, thus the very bottom of the tank tends to be split left to right.
The fill connector is as you would expect, pipework runs up to the top of the tank to allow it to be filled to the brim.
The FIA connector reaches down into the fuel collector, where the 1L sample needs to be taken. It's taken from the Collector as in theory it should always be full with over 1l of fuel, this also saves the FIA having to scavenge fuel from the very bottom of the fuel tank itself.
