I am building my wings and have been thinking about fuel lines. I want to use a fuel-injected engine (most likely an IO-360 180 HP). I spoke to a friend of mine and asked him if he had a return line from the engine (for fuel overflow) to the fuel thanks and he told me no. He also has an IO-360. He told me that his return line goes directly to the fuel valve. I have a few questions. When the overflow fuel from the engine goes out on the return line, is there a mixture of air and fuel or is the line just full of fuel? Has any one done the same thing he has done? He says it works fine and has had no issues. His fuel valve is Left/Right and Off. So he needs to switch thanks every 30 minutes of flight. I want to have a fuel valve with Left/Right/Both and off. Would a system like his work with the fuel valve that I want? And last, if you have a fuel system diagram for your bird, can you please post it. Like every person that builds an aircraft, a lot of learning needs to occur and this is a section that I am weak on. Thanks for any help.
