Scotty, No it is my inside the petcock sintered metal fuel filter. It is detailed in tips and trick under the carbs section. Hondaman has tested it and thinks it works great and thinks I should sell kits. I have 60 K miles on my K2 and I think it works great. I really want people who ride and can give me an opinion as to if this make sense on a very limited sales basis. They are cheap to produce and I really was looking for 4-5 people planning to put some miles on an early CB750 to tell me what they think Thanks Dan
