I talked this issue over with Lancair and they have indicated that the pump should be as low as possible - under the co-pilot floorboard and mounted sideways.  I couldn't avoid a right angle, but I think the height of the pump is the crucial element as the pump primes itself poorly.  I've attached a couple of photos of my installation.  (These and other photos in high resolution are also available.  I can send them directly to you, if you like, so as not to overload the mail server.)
