I'm installing an electronic ignition/electronic fuel injection system on my 0320 H2AD and had a question I was hoping the group could help me with. The supplier of the system (Tracy Crook at Real World solutions) recommends drawing from and returning to the same tank and using a transfer pump to move fuel from the other tank. I have opted to do this to simplify installation and cost (duplex valves are EXPENSIVE!!!). I installed 2 bulkhead fittings in my left tank (one for return and one for transfer) The facet pump will act as a one way valve (keeping fuel from the left tank from flowing to the right), but will allow fuel to flow from the right to the left tanks when the pump is off. My question is --- is there a problem with this? I can't really think of a situation where this will be a bad thing. If the plane sits a while with more fuel in the right tank, the tanks will equalize, but this does not seem to be a bad thing. Can anyone think of a reason why I would not want to do this? I could put an electric valve (primer) in the system, but I'm not sure it is necessary. Just for info, I plan to leave the original valve in the system. In case of pump failure I can always suck off the right tank and return to the left and then switch back. It will also leave me a way to completely shut off the fuel in case of an emergency landing. Any info will be greatly appreciated.
