1L or full tank added should take 25sec. We dont set the time it takes we can only say if there is fixed time or not. Tyre change is optional but tyres are changed at the same time as fuel and it only adds 5 seconds to a fuel stop, with tyre wear seeming fairly high I dont see how saving 5 seconds in the stop would be a net gain in the race as you could lose 2 seconds per lap on worn rubber.
There is a max stint limit of 65 minutes, this means you cant run longer then 65 minutes without a pit stop. The real series has this rule to ensure no car gets a big advantage by using less fuel as some do, its also why fuel time is fixed to ensure the more effiicient cars dont get an advantage on their fuel stop. This means if you need to stop early you will need 2 stops even if your car could make the distance to the finish. You only need to add fuel in one stop however so a second stop you can do whatever you want.
Things to be carefull of in the stop, you dont want to change brake pads as its 1:15 to do this and if your strategy has different pads to what you started on, it will default to change pads. You can simply uncheck the pad change in pit mfd once in car. Best to do this on the grid before the race or on the warmup lap which is the best time to set your strat up.
Pit entry is also pretty quick and blind, its very easy to come in too fast. Practicing some pit entries will help you avoid a pit speeding penalty. The limiter only works in 1st gear and its fairly strict now at the entry.
