Fuel Selector Button?

Hey guys,
hopefully someone can help me here, as I’m still pretty new to the community.
On the Cessna Caravan you have 2 valves on top for the fuel flow (see picture) and I’m trying to bind them each to a separate button, but I dont know what they are called in the control option menu.

Hopefully someone can help me out here. Would be much appreciated.

Regards

They should be called Fuel Selectors Left/Right/Both. Make sure you choose „all“ in the keybindings to find them. Otherwise it will show the enabled ones only.
