Simplifies the problem. If you are using the fuel pumps that Tracy supplies, you do not need check valves as they have them inside. You will need filters after each pump though. If either of the pumps craps out, it will fill the injectors with residue and you will not then need the spare pump. Bill B -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of randy echtinaw Sent: Tuesday, December 02, 2008 6:59 PM To: Rotary motors in aircraft Subject: [FlyRotary] Fuel system Gentlemen, Because a large majority of homebuilt problems are fuel related I am trying to make my system as simple as possible. This is a biplane with a 20 gal. and a 10 gal. tank in front of the inst. panel, RX-8 engine. The only "known" problem I have at the moment is my fuel return. I would like it to return to the main tank only. This would mean burning off 2-3 gallons from the main tank before switching to the 2nd tank. But, this might mean I am setting myself up for a future "pilot error" in fuel management. If I return to both tanks I would need another selector and cockpit control which is making the system more complicated and, again, potential "pilot error." So, suggestions . . . Thank you very much, Randy
