Is there a valve to switch between the two fuel tanks?

[nashville bassman]

My L-1R26 has two fuel tanks. Is there a valve that I need to turn to pull fuel from the secondary tank or does the engine pull from both tanks automatically?

Look for a y connector between the fuel lines coming from the tanks or there has to be a manifold or valve system to switch them. How's the weather up there tonight? Love Nashville!!!!! :)
