Ok, I've been thinking about the fuel system a lot and I think I have finally came up with a system that I like. It has a lot of bennifits:
1. No Fuel in the cockpit 2. Minimul Ful line runs 3. Simple with few points for leakage
Drawback is it requires remote switching. I really like the idea of remote switching but it has the drawback of what if it doesnt switch. To minimize the risk I went with a Parker Marine switching valve. It is only 3 lbs and has a very high reliability. The rest of the system is strait forward and simple.
