My fuel pressure held constant from sea level to at least 12,500' without it, even in very hot weather". Jim Actually you don't even have to use it for starting, but only for priming. In the wintertime when my battery has been down and the temperature so low that I couldn't pull both starter and boost pump, I have succeeded in starting by priming first, switching off the pump and turning the starter. Since the fuel lines are primed you get fuel from the engine driven pump as soon as the engine fires. I think the most important use of the electrical boost pump is as a stand-by for your engine driven pump should that fail during take-off and landing. I have that item as "on" or "off" on my "Before take-off", "Climb", "Before descent" and "After landing" checklists.
