Thread-Index: AcTn0z6jrFnGeIakQc+PNRAwf9LqMgAXE2Lg From: "Mark R Steitle" To: "Rotary motors in aircraft" If I can add my 2 cents... if you wire both pumps to one switch, you've created a single failure point. IMHO, two switches would be better.

Dana, I strongly recommend that you wire your two pumps so that both may be operated simultaneously. I turn on both pumps for take-0ff and Landings. Should one pump fail, I would not need those precious seconds to recognize what had happened to react correctly and get the fuel pressure back up in time. So look upon it as insurance. Once at adequate altitude I turn one pump off.
