The Sullivan Skywriter will be your best bet on pumps. B&B makes a smoke muffler/manifold that is fairly cheap, Bold Muffler makes a pitts style smoke muffler designed for the G-23. Super-Dri is the best smoke fluid on the market, but diesel fuel, transmission fluid, and kerosene cut at 33% does pretty well. you need to use Neoprene tubing from the muffler and Tygon everywhere else. Make sure your smoke tank is much smaller than your fuel tank. Good-luck
