If I pump my Nauta (brand) fuel bladder dry, it will briefly make the engine run rough, but the instant I shut the transfer pump off it resumes normal operation, really a non issue. Nonetheless, after 22 years of flying fairly often with a portable ferry tank of various kinds, I choose to initiate the fuel transfer process at cruising altitude, rather then approaching a gravel bar. That makes the entire discussion of what position any fuel selector/which tank should be in irrelevant. KISS!

This discussion, and esp this comment, brings to mind the recent forced landing into a river by one of the youtube guys in his Cub.

I've never had an insurance company ask what size tires I use

I was wondering about that? I have deliberately run a wing tank dry in the climb to see how quickly it would change over and get back to full power. It caught surprisingly quickly and was a none event. Hardly lost any height, but i was expecting it and changed tanks quickly.
