how can i open the fuel cap valve?
You will need a “penta-key” and a bit if patience as these are very easy “rounded”.
First time I open a (new to me) SRV/fuel cap valve, I usually let it soak a couple of days in either thin penetrating oil or a 50/50 mix of Acetone and Transmission oil.
A Penta tool could look like this one:
Optimus Fuel Cap SRV Tool wrench Pentagon / Five angle | eBay
I haven't tried this tool though - I got mine from @Spiritburner (the Fettlebox). Good luck.
Thanks a lot
Count the number of turns when unscrewing the SRV cap. So you can reset it to the same position and pressure setting.

You can use a 5 point TORX like bit too if you are careful, you might be able to get one of those locally at an auto parts store. There is thread locker on it from the factory, you'll need to hit it with a torch to break the thread locking compound - this will destroy the small pip, so make sure you have a replacement handy.
Careful is the key word.
The Torx is rounded and can easily damage the part.
