Thanks DrDeath and Billy Hell for your info.

I think I'll check out those rubbermaid jugs.
As far as my plumbing, I 'm going to install a tee between the vent lines from each jug and exit the one line out of the field box to a fueling dot. Then install 2 more fueling dots, one for the ducted fan fuel and the other for the prop plane fuel. For a total of three fueling dots mounted and labeled on the field box. When I want to refuel I'll uncap the vent and one of the the fueling dot then plug in the pump line from the pump mounted on the out of the box. When I bring both planes to the field, this will keep me from having to go into the field box and switch lines between the jugs and the pump every time I switch planes.
