I was thinking of running an electric rotary vane pump very close to the tank to a big diesel water seperator/ filter. I figured it would help on startup by not having the engine mounted lift pump pulling so far. This would of course be the weak link to the fuel system IMOP. I have had the rotary vane pumps die. They also push an incredible volume. I would run the engine return to the big water seperator/ filter abd a big return back to the tank. In my fuel injected 302 setup, which is where i have run a setup like this, it supposedly keeps fuel temps low by moving it through steel lines on the frame. It all sounds good except when the pump breaks. You could add a valve to bypass the pump if it died but then the whole system is really elaborate (read pain in the a$$ to fix or maintain). Also Rotary vane pumps can be LOUD. When I get there I'll post results. Caution, this could take a year!
