I had a very high pressure in my tank every time I filled up during a long ride around town (> 50 miles)
My tank was later replaced (after signs of cracking) and the Y fix completed - No more large pressure releases since... why ?? i don't know.
Warranty over now....The CC gets the boot this weekend!
You can test the electronic valves with the GS911 device.
