Not on my checklist. Not that I’ve seen. I guess it’s a good idea to “exercise” this (as previously discussed).
I’m still leery, though, of playing with fuel selectors prior to flight. I’m more inclined to do the exercise post flight, perhaps while taxiing in or for fuel, etc. That would give the after-shutdown-inspection and pre-start inspection (next use) a chance to spot any leaks or abnormalities.
