The barons have that lovely up for HIGH, and down for LOW function, go the wrong way and the engine stops! I do remember a Bonanza E33 landing on a beach at the Gold Coast a few years ago when pilot turned on the fuel pump when turning a long finals onto 14 at OOL, ended up on the beach, very expensive mistake!
VERY strange when one manufacturer has a fuel pump that you turn on for takeoff and landing, and the other has a HP fuel pump that if you use it when the engine driven pump is operational will flood it until it dies, in the baron you certainly need to be pretty sure what each function is for when both are on the same button!
