If you want to make a change, you must solve the WHOLE problem, not just the part you want to solve. You need to make that valve easy to operate, operate in a sensible way (flip right to the right fuel tank, not left tank, have a 'both' setting, etc.), and make it ergonomically work. In this case, the ergonomic issue could have been solved with a "dead pedal" right next to the right rudder. This is a fixed surface adjacent to the pedal in the cockpit wall you can put your foot on and press. There is one to the left of the clutch in most well-setup sportscars. With this, the pilot could press and reach around without any input on the rudders. But, this "builder" couldn't be bothered to actually solve the problem and he killed a bunch of the pilots using his update, including John Denver. Criminal, if you ask me.
