> "Ethanol will eat up your fiberglass (epoxy) tanks also." My main tank (17.2 gallons) is aluminum, custom made to fit Ken's dimensions. The 4.2 gallon aux tank in the starboard wing is vinyl ester and is supposedly ethanol-proof but I've taken no chances. I've never put anything but avgas in it. Ken was going to put an identical tank in the port wing and plumbed for it during the build but told me the aux tank in the right wing took so much time and trouble that he decided to forego the one on the left. After fueling on cross-country trips - the only time I use the aux tank - the plane is a little right-wing heavy until I've burned off enough space in the main tank to make room for the aux fuel.
> "For gravity feed systems . . ." I assumed for the longest time that my engine/carb needed the electric fuel pump in order to run. The plane came with a primary pump and a back-up pump that's available with the flick of a switch and figured the back-up fuel pump was there for a reason, but one day I was cruising along and turned the primary pump off just to see what would happen. Nothing happened. It continued to run as if the pump was still on. Since my Ellison is top mounted I have no idea why this happens - maybe due to the "siphon effect"? I had been so concerned about being dependent on an electric fuel pump that I installed a secondary electrical system devoted to just the fuel pump and the Trutrak artificial horizon. These items are powered (if the back-up electrical system is being used) by a small AGM with enough capacity to keep me going for several hours. I had considered that a major electrical system failure such as a failed master switch would put me out of business and since I fly at night and in weather, having electrical back-up for these items seemed critical. But nothing has ever failed and I've never used this secondary electrical system. If my master switch or other critical electrical component ever did fail, I now know the engine would keep on running with gravity fed (or siphon-fed, dunno) fuel and the magneto. Whoever has this plane after me will probably want to get rid of the battery and secondary bus & wiring to save some weight. ____________________________________________________________ How Old Men Tighten Skin 63 Year Old Man Shares DIY Skin Tightening Method You Can Do From Home http://thirdpartyoffers.juno.com/TGL3141/54d5478047e8947803983st01vuc
