ok I thought that you might have put a check valve between the two rails, that why I wanted to clarify

so mixing that volume would not be a major concern, how large are the fuel tanks 10 L ( ~3 gallons)
if so the mixing would be a tiny influence, even if you just put a dual throw valve on either end 
of the rail. Or was your idea to mix the 2 fuels?
