I have a fuel pressure alarm programed into my EIS. Should the fuel pressure go low I will turn the electric pump on. I also turn the electric pump on when the fuel level is below 4 gallons in the tanks. (this should be very seldom) This satisfies my desire for a comfort level. My reasoning for not running the electric pump during take off and landing is that those are the most likely times for accidents and I would not want the electric pump running and possibly pump fuel out in the event of an accident. My plans are to install an inertia switch to open the main power solenoid then I would be more comfortable running the electric pump on take off and landing. This are only a hillbillies opinion so take it for what it's worth.

Is it req'd or will the std fuel pump pick up fuel from the tanks behind the seat. I am pulling my fuel off of the top of the tanks with tube that go to the lowest point in the tanks. I think it was Steve I was talking to and he said he only used his on take off and landing. > > ________________________________ Message 3 _____________________________________ Time: 08:33:54 AM PST US From: "Vince Nicely" Subject: Re: Kolb-List: Firestar Glide ratios with and without power --> Kolb-List message posted by: "Vince Nicely" Hi John, The time for the 2000 ft decent was 3 minutes and 15 seconds for a sink rate of 615 ft/min at idle and the sink rate was estimated at 584 ft/min with the engine off. My plane has the 68" IVO, too. I made an error on the previous post. Vince Nicely > > > Vince, > > How much time expired on each test?

I have a 68" two blade IVO. > > John Jung ________________________________ Message 4 _____________________________________ Time: 08:33:54 AM PST US From: "Vince Nicely" Subject: Re: Kolb-List: 72" Prop on Firestar II --> Kolb-List message posted by: "Vince Nicely" Dominic, Sorry, my error.
