Deadstick is correct that your best route to success is a pumped engine. Trying to attach Iron Bay or Cline to an Atlanta is analogous to a comment attributed to Dolly Parton's dad. He mentioned that her top side looked like someone trying to put ten pounds of flour into a five pound sack. The Atlanta's nose section is just to small to install the regulating equipment unless you hang it outside.

Although, Deadstick(sorry Dan) is a bit off about the tank being at the CG. It is really a good ways forward of the CG. But that really has nothing to do with your problem.
