Thanks for the response on fuel system ideas.  Rusty explained the secondary rail and I hope I got this right.  Fuel is delivered at pressure to primary injector rail then to secondary rail then to regulator which feeds the return line back to the tank.  My thinking was that i intended to connect both strake tanks together with a tunnel and a sump in the center where fuel would be pumped to the rail system.  Even though the tanks are connected I was not sure how quickly they would level if fuel was returned to only one tank.  I was thinking of splitting the rail system into two and returning to both tanks ie forward rotor to port tank and rear rotor to starboard tank.  If the fuel could level on all conditions then the fuel could be returned to one tank.  To implement this you would need two primary rails two secondary rails and two regulators.  I may not need to split the rail system.
