A-Fuel Pumps

Anyone with experience running both Nuke and waterman pumps? What is the difference in the pump characterists? I have a Waterman 14x14 which I am running and a 48 gal. Nuke that I have not run.
I have flow sheets on both but they don't give much info. as they were nor flowed using an orfice the size of nozzle area. I do have computer info on the Waterman off car but not the Nuke. This is a wonderful site if you run alcohol car but information concerning fuel systems on fuel cars is more difficult to discuss than getting bomb info from Los Alamos.
