Or go to plumbing outlet and ask for a cast brass check valve for water circuits. Should be about $15 each and the mount vertically (gravity close) 1/2NPT.
Would either of those divert the backflow around the fuel pump?

If I get into solenoids, I'd just use a 3rd 3-port valve. I'd trying to cut down on the wiring & switching by going with something that will just divert the flow when it backflushes.

You could avoid this mess by making biodiesel. Then again, I am a silly bed wetter.

Exactly... Biodiesel is for bed wetters! Seriously, I'm not quite sure I have my head around your concept. Part of the problem is I've never used a check valve, so I'm not entirely sure what I should be looking for.
