That really was a neat video; thank you very much for sharing it. I never realized how rough the welds and castings were on the tank, nor how filthy the inner side of the rear fuel tanks get from the exhaust. I think you'd need about THREE smoke units on a model to try and match all the exhaust smoke that thing puts out!
Or you may need only one of these....
