The following instructions are very important.  They should be read through carefully.  The following is a sketch to help aid in the understanding of these instructions.  If you need further help you may call technical support at (888) 436-0899, or may refer you to our plant engineers.

Step 1) Mounting The Fuel Vaporizer GLS
  The Fuel Vaporizer GLS needs to be mounted in a cool upright position, away from the engine, and no lower than 8" below the intake manifold. The firewall, strut towers, or on either side of the radiator would be good places to mount it. A bracket may need to be made for certain applications.
                          Special Tip Keep the unit out of the way of  "hood close area" and/or  "hinges".

Step 2) Installing The Gas Line Tee
      Warning - Cutting into a gas line will result in some gas spillage, it may even be under pressure and be released in the form of a spray. To avoid danger take these precautions:
                                          1. Release gas cap.
                                          2. Keep heat and fire away at this time
                                              (light bulbs, cigarettes, etc.)
                                          3. Keep electrical cords and equipment out of the way.
                                          4. Install when engine and muffler are cool.
                                          5. Wear safety goggles and appropriate clothing.

Fuel Injected/                                           Fuel Systems
Throttlebody
   Since vapor gas is injected right into the intake manifold, it doesn't matter where we get the gas from.   So, on fuel injected systems install the tee into the return gas line.   If it doesn't have a return line (like the newer Dodges as with some Toyotas and Fords), tee into the high pressure gas line and see  "special tips"  below.
Carbureted
   Install the tee between the fuel pump and the carburetor. There should also be a fuel filter between the tee and carburetor, sometimes this is in the carburetor itself.   If not, then the gas line will need to be flushed. Unhook it at the carburetor and with the tee in the line, start the engine enough to flush the line out into a container.  Otherwise rubber debris from the hose might mess up the needle valve in the carburetor.
Special Tips
  • The fittings in the tee may be replaced with other fittings to adapt to the fuel line.
  • If there is a lot of pressure retained in the fuel line after the engine is shut off, such as a fuel injected high pressure line, a solenoid may need to be installed between the tee and the Fuel Vaporizer GLS to stop the flow of gas to the atomizer after the key is turned off. This will keep the vehicle from flooding next time it is started.
  • To avoid vapor lock in the tee on carbureted engines, place the tee in a cool spot, maybe on the firewall, and reroute the gas line to it.
  • Step 3) Connecting the 1/8" copper tubing
        Fasten one end of the copper coil to the tee (unroll as needed). Close the Gas Flow Control Valve on the tee and start the engine. With engine running, adjust the control valve so gas is coming out of the tubing at a fast drip. Now, turn the engine off and fasten the other end to the Fuel Vaporizer GLS.

    Step 4) Connecting the PCV Valve
        Inspect the PCV Valve for good working order (it should rattle). Connect one end of the 3/8" hose to the PCV Valve and the other end run to the nipple on the Fuel Vaporizer GLS marked PCV In, but do not connect it.
    Special Tip
  • If you can't find the PCV Valve. Look on the emissions schematic located under the hood or check with a local dealer. If you do not have one see troubleshooting.
  • You may need to adapt the hose end to fit the PCV Valve.

  • Step 5) Connecting the 4'(foot) Vapor Out Gas Line Hose to the Intake Manifold
        This hose can be longer than 4'. Connect one end to what the PCV Valve originally hooked up to, (this might be a network of vacuum lines). Then run the other end to the nipple on the Fuel Vaporizer GLS marked PCV Out but do not connect it.

    Step 6) Adjusting the Vapor Control Lever
        Connect the temporary clear plastic hose between the PCV Out nipple and the 4' vapor hose. Leave the PCV In line disconnected.   With the engine running, adjust the vapor control lever forward until gas is barely seen streaking the sides of the clear tube. Then remove the temporary clear tube and connect the hoses to the Fuel Vaporizer GLS.
      Now, if the fuel mileage is about the same or a little higher, then continue adjusting the vapor control lever forward about a 1/16" at a time until the fuel mileage peaks out. If you experience a decrease, then adjust the vapor control lever back a 1/16" at a time until fuel mileage peaks out.

    Step 7) Checking the Vaporizer Chamber
        The chamber collects the emissions that normally are routed back through the engine. So, when the chamber is half full unscrew it and dispose of the emissions (oi) like you would used motor oil. This may only need to be done once every month, but check it once every two weeks until you get accustomed to how fast it fills up.

       Special Tips & Concerns:
    1. If the unit is restricting too much air, then a simple bypass may be installed. The two lines that are hooked to the unit are both teed into with a valve between them. Open this valve untill the right balance of air has been accomplished.

    2. Vapor locking occurs when the gas starts to boil inside the tee or gas line. This can be taken care of by rerouting the gas line and tee to a cooler place such as the firewall or insulating them from the heat.

    3. On fuel injected vehicles the return gas line will sometimes be smaller than the supply line and will be free of fuel filters and auxillary fuel pumps.

    4. If gas drips in the sludge chamber after the engine is turned off make sure the tee is in the return line. If there is no return line or the gas line has a lot of pressure on carbureted units, then a solenoid/valve kit may be needed to install the 1/8" copper line. This will shut the gas off running to the Fuel Vaporizer GLS when the ignition is turned off. Email us to find the cost at:
    custservice@agsint.com

    5. Sometimes the injectors are not capable of closing down enough to compensate for the added vapor even though the vehicle gets an increase in mileage. In such a case the vapor control adjustment may be turned down and a little mileage sacrificed. Or you may talk to your local dealer, or a certified "mechanic" for injector or computer options.

    6. If your vehicle does not have a PCV valve the unit may still be installed. Look for a CVC line or a vacuum line that runs from the crankcase to the intake manifold and use this line If not, email Fuel Vaporizer GLS for an air return control.

    7. If the "PCV line" is not allowing enough air to pass through it. The PCV valve may be a partially plugged, or a tee with an air adjustment may need to be installed in the PCV line, as to allow more air to enter the system.   Questions or comments, fax us at our internet fax line: (208) 692-3632 or e-mail us at Fuel Vaporizer GLS, thank you.
