Dave, I use flexible vane pumps by jabsco at work all the time. They self prime to a surprising height. When I came out of layup I vented/flooded the strainer. The pump might have had to pull 6" up and through 3' of pipe. I think it was probably flooded by the time I released the decompression levers.
As a side note: I also have a globe "run dry impeller" AND a Lifeseal cover. Both are supposed to allow for multiple minutes of dry operation.
