I am building a Super stearman right now also. I guess by now you are probably finished with yours so I wanted to see what you did with your smoke tank. I found that I can fit a 14oz tank directly above the supplied fuel tank. With a little foam I think the fuel tank will secure the smoke tank perfectly. I was going to drill an opening large enough for the mouth of the smoke tank to exit the firewall just like the fuel tank. That way the smoke tank stays on the CG and all my plumbing can stay outside the fuse. There is plenty of room in the cowl for the smoke pump. I am using the TME simple Smoke Pump II. Everywhere I read it says I should not mount the pump directly to the firewall because of the vibration. I am using a saito 150 and I hear it vibrates a lot. Does anyone have any ideas how the pump can be mounted on the firewall and not vibrate too much. I was very happy when I realized I could get the smoke tank above the fuel tank, but then bummed when I found out I shouldn't mount the pump to the firewall. Does anyone see any other problems with this setup?
