You should really try the one from Team Orion, I'm sure it is the same as Kyosho.
I have been using Team Orion CRF Constant Pressure Device CPD #ORI88551 at my track (SpeedWorld) for two months and I like it a lot. For one, the fuel is sucked out of the tank too the drop and the cars does not even lean out one bit, it just runs it dry. That could be good or bad thing, that is up do your decision, some racers like to know if they are running out of gas, this device gives you no warning.....
I also heard from someone and I can not remember that the device does not like to be blipped a lot; I do not blip but as not experienced any problems except it does leak very, very little.
Butt the device right up to the oulet of the pipe, minimal gap as possible.
www.speedworldraceway.com they have them in stock.
