I watched my smoker in action while I have the top off my Tiger. I noticed that the angle is not very steep were you add the fluid, so it doesnt want to go into the smoker, rather stays in the "exhaust tube". I was wondering if it might be a good idea to drill a hole in the top of the smoker and run a seperate filler tube up under the engine grill. You could then use a syringe to fill it. When filling your stock smoker, are you suppossed to fill by only one tube? While the computer fan idea is inventive, I prefer improving the stock setup as the fan method looses the puff, puff that is in sink with the motor.
