The only way i see that is possible is with some sort of canister system where you simply take off the empty one, lock into place the new one.
You should ask Gordon Murray on how to do it.

In 1983 he managed to design a pressurized rig which delivered 100 liter (around 80kgs) of fuel in 3 seconds.

Bike racing at the Daytona 200 40+ years ago..
.. featured aircraft-style, large diameter hose, clear-vented, dry-break, safety-type, quick-refuelling systems..
..so it cannot be that bloody hard - now - to get right.. surely..

Is there any plan to reintroduce the awful Q3 on race fuel rule?

...this is just dumb.
The refueling ban is inconsistent with F1's recent push toward efficiency, because it doesn't make any sense to carry the fuel needed for the last lap of the race from the first lap of the race. This is doubly so when you consider that each (unavoidable) pit stop ultimately represents a missed opportunity to make the cars that much lighter/quicker/more efficient.

Of the many knock-on effects of refueling will be the end of grotesquely long wheelbases. That will make chassis lighter, stiffer, cheaper, less sensitive to aero changes, and easier to set up.

And since there's a very strong correlation between wheelbase and directional stability, the cars will be more nimble and more difficult to drive as a result of reduced stability.

In short, I think this is the best change F1 has made in a looooooooooooooooooooooooooooooooooooooooong time.
But teams wont put a 50kg fuel tank in their car IMO. They will opt for a 75kg cell instead, for more flexible strategies...

I can't envision anything greater than 55-60kg, if not less. To make the most of a 75kg fuel cell would require tires durable enough to remain competitive for at least 3/4 of a race, and I just can't see that happening. A car in such a position would likely be easy picking for any cars light enough to get more life out of the softer compounds.

Moreover, since the teams will have free rein when it comes to tire selection, I'm pretty sure they'll adopt development strategies aimed at eliminating any need for the medium and hard compounds. (We'll almost certainly never see those compounds used in qualifying, which means we'll almost certainly never see them used to start a race.)

ah well , back to boring racing
the turkeys have voted for christmas ...again
the essence of F1 should be to finish first , not finish fast , fangio knew that and said so

all I want to see is better racing , this sure isn't the way to go about it , buying success is easily stopped , how about the millions spent on front wings by the bige teams ....oh dear , if we dictated simple ones cars would be able to follow closely and overtake , can't have that we might get beaten
to the optimist a glass is half full ; to the pessimist a glass is half empty ; to the F1 engineer the glass is twice as big as it needs to be

About the unsafe release when refuelling: couldn't they implement a sistem that prevents the engagement of first gear when the pipe is still attached? In this case the driver can't start and take away the pipe like in the past

They probably could, though I believe there's only ever been 2 recorded incidents of this. Plus, that doesn't account for tampering (like that that caused the beneton fuel fire).

Just before refueling was banned, and in response to Massa's incident in Singapore, the pit lights used by some teams in lieu of a "lollipop" were generally equipped with a feature that prevented a green light until after the fuel nozzle was removed from the car. Eventually, they were programed such that the green light was triggered directly by that action (unless overridden by the "lollipop man" due to pit lane traffic).

I think this is probably still the best solution, as I don't think it's a good idea to implement a system that can take control of the car away from the driver.

I suppose from an engineering point of view that could do lots of things. One of my contentions with the way F1 handles refueling is that in the past they allowed the teams to develop their own refueling systems. (See the above pic and post by WilliamsF1)

IMHO whatever system used should be one that is owned and maintained, and frequently inspected by F1 and that all the couplings between car and fuel rig standardized, and the whole system tested throughly before introduction. Frankly I believe that flow rates should be limited by gravity and atmospheric pressure. Of course this will make pit stops linger, but isn't on-track racing the point anyway?

The refueling rig used before the ban was a standard item made by Intertechnique, an aircraft fuel system manufacturer. These generally performed safely, at least when the teams did not tamper with them to increase the fuel flow rate (as in the Benetton 1994 fire).

Tampering...
You have returned to the discussion of my initial post on this topic. Regulations and enforcement, which is why I desire a common fueling system.

Mercedes F1 boss Toto Wolff said: "We discussed many topics. Refuelling was banned because of cost and because the pit stops were taking too long. But we want to re-explore it and see if we can make pit stops for fuel and tyres happen in the same time it takes to change the tyres now - two to three seconds.
"We have agreed to explore this avenue and the cost involved because it could be spectacular. If it's too expensive, we won't do it."

This is downright scary, it would require high pressures to force any respectable amount of fuel into a tank. High pressures and gasoline is a recipe for disaster.

If it's too expensive, we won't do it. For whom? Just the members of the Formula One Strategy Group composed of Ferrari, Red Bull, McLaren, Mercedes, Williams, and Lotus, or all teams? For the smaller teams with already stretched budgets, this is an unwanted expense that forces them closer to closing their doors.

And how about Haas? Just like the three teams that entered and have now folded, the game changed before they even got their first race in. Is this any kind of financial stability for any new team to sign up to participate, and learn that when it's time to compete, the financial demands have risen?

If you´re talking about the canister system my idea would be gravity fed so no pressure in the canisters.
Essentially replacing fuel tanks except they will be much more accessible then today where they are an integral part of the cars design.

Actually i think PlatinumZealot is on to something. I think that direction is the way to go if you want to maintain extremely short pit stops and still be safe.

If pit stop time is no isse then WEC way of doing things is best, it doesn´t get much safer then that.
