Hi, Dana....I prefer to have both pumps on at the same time for takeoff and climbout to at least traffic pattern altitude. Then only one pump is needed. The reasoning for this is that if the pump quits on climbout, the engine will likely quit very fast....by the time the average pilot realizes the cause and takes action (by turning on the alternate pump), it's very likely that the engine would already have quit. Restarting could get hairy at 100 feet. Just my opinion, and believe me....I could be wrong. Paul Conner

Subject: [FlyRotary] Fuel pump question.
Man am I ever going to expose my serious lack of electrical knowledge here:-) I'm planning on using a single pole double throw switch to activate one or the other fuel pump, but not both. Is there ever any reason to have both pumps on at the same time??
