This is the Team Orion CRF Constant Pressure Device. When an engine is running at full throttle, a large volume of burned gases flow through the exhaust. Part of the gases are expelled out of the exhaust pipe and part of the gases find their way towards the fuel tank. Engines have 2 main settings, High Speed Needle (HSN) and Low Speed Needle (LSN). Engines are tuned to have the highest speed possible with the HSN and to be stable at idling with the LSN. When the engine stands idling, only a small amount of pressure is created, when the engine runs a full throttle a large amount of pressure is created.

Problems arise when you switch from full throttle to low speed, high pressure generated from running at full throttle is still present and it is pushing fuel to the carbutaror inlet though the carburator is closed. Because of this the mixture will become too rich, causing slower acceleration and wasting fuel. The Team Orion CRF Constant Pressure Device acting as a pressure valve system, effectively resolves this problem by regulating the amount of pressure going to the fuel tank. The valve allows a constant amount of pressure to be sent to the fuel tank, by opening or closing itself depending on the engine’s rotation speed.

Constant pressure allows for:
  • Easier adjustement for any type and size of engine.
  • Better low end response because the mixture always remains correct and does not enrichen because of the excess pressure.
  • Longer run times because there is no excess pressure pushing un-needed fuel inside the engine.

This thing is a piece of shit!

The pressure in the fuel system after running at a varying throttle range is the only thing that keeps the engine from running lean!

The "loading up" effect is caused by atomized fuel and air condensing on the inside of the crankcase, NOT TOO MUCH PRESSURE IN THE FUEL SYSTEM!

If you spend 40 bucks on this you're a dip-shit!!!

I would imagine any excess pressure in the tank from full throttle will be reversed and travel back out to the exhaust when full throttle is closed.

OK, this has been on "Back Order" for a while now.....what's the verdict???? Is this thing the greatest thing since sliced bread, or is it a waste of $$$????
