This is the engine compartment with the metering rod I fabricated (see thumbs below for drawings). The metering system I first fabricated I mounted directly to the bottom of the bubbler. This works great and solves the problem of getting the liquid siphoned out of the bubbler properly. Make a note I have another design that should work above the water line and not require putting a hole in the bubbler that may be preferable. I haven't tested that yet, but this one is in place and should work fine. I had to remove the oil from the water running 100% water in the bubbler. Oil and water do not mix, so only water comes out anyway. Adding bubbles to agitate the mix worked to mix the oil and water, but left me with a homogenized mess that had the consistency of margarine clogging up the metering system. If I am to add any oil to the mix later I'll have to add yet another small bottle and separate metering system. Another change to make a note of, I added a tube that takes air directly from the exhaust to vent the system and bubbler. The rod passes across the top of the engine compartment to gather a lot of extra cooling. Exhaust has some unburned fuel, so this should further help in boosting mileage. Not seen here, I also took the gasoline tank vent and connected it to this system. On these old VWs the gas tank vent was dangling open to the air in front of the car. The smell often found its way inside the car especially when the tank is very full. Venting it to the GEET system should make use of the fumes to improve mileage while making things smell better inside the car. Note on the copper tube coming from the GEET reactor to the carburetor which should contain the GEET gas has an aluminum bar attached to it. This acts as a heat sink to remove heat so the GEET gas arrives to the intake as cool as possible.
