HOME CNG conversion kits cylinders tanks

Compressed Natural Gas (CNG) is one of the lowest cost and environment friendly alternative fuels available.

All you need is a CNG Conversion Kit, and a CNG Tank with Valve and a Mounting Bracket for the Tank.
You can use multiple tanks for a longer driving range with any of our conversion kits.

New Price Matching
We will match the price of any USA stocking competitors advertised price on any comparable CNG kits, parts or tanks.

Warning About Other CNG Kits
If you purchase a conversion kit from other companies, the kit may not be complete and you may need to spend a couple hundred dollars purchasing the parts needed to complete the kit. We have had to supply parts needed for other kits costing the buyer as much as $250. Make sure any kit you purchase is complete with nothing else needed. All our kits are 100% complete except for the CNG tank and mounting bracket. Make sure your your kit has an aluminum adjustable mixer or you will not have peak performance when running on both fuels. Make sure the kit for any gasoline engine has an automatic self adjusting feedback controller using an oxygen sensor to maintain the proper fuel ratio. If it doesn't, don't buy it.

All kits for 8 or 10 cylinder gasoline engines must have our high output regulators, or dual regulators, or the engine will run lean and excessive power will be lost. We have tested all regulators and none will provide sufficient fuel for an 8 or 10 cylinder engines except our regulators.

You do not need to have an EPA Certified conversion kit on Vehicles over 2 years old. Our conversion kits are EPA compliant for all other vehicles as no engine devices are tempered with.
See our FAQ page for more information.

You cannot fill from the Natural gas at your house unless you have a home filling station.

How our Mixer, Single Point Injection, Air Intake, Conversion Kits for all Gasoline Engines Operate
We have two kits for fuel injected engines. The EWS kit is lower in cost and simple to adjust with no computer, but we recommend purchasing the software and the computer cable as you can fine tune it and troubleshoot it better. The Millennium kit cost a little more but has many more features and comes with the software and computer cable. These kits are both low cost and easy to install. These kits are available for all EFI electronic fuel injected or throttle body gasoline engines even turbo or super charged engines. They even work on MDS fuel saver engines that shut off some cylinders when not needed. We have kits for carbureted engines.
This is how they operate: The system is wired to turn off the fuel injectors when running on CNG. No other engine wiring or engine devices are changed or adjusted. This is why all our conversion kits are EPA compliant as they do not tamper with any engine devices. You will start the engine on gasoline and automatically convert to CNG as soon as the engine reaches the set RPMs. It will run on CNG until the engine is turned off, or you push the button on the dash to switch to gasoline. The regulator reduces the high pressure CNG coming from the CNG tank to zero pressure. The mixer (venturi) is installed in the air intake between the air filter and the throttle body which provides single point fuel injection. The mixer creates a negative pressure so the gas is sucked out of the regulator as the air volume is increased as the throttle is pushed. An oxygen sensor on the engine's exhaust is monitored by the CNG controller which controls an electronic valve (stepper motor) installed on the zero pressure CNG fuel hose going to the mixer to provide the proper fuel ratio at all times.
On all gasoline engines the combustion air has always been precisely controlled with the throttle plate. A mixer kit uses this precise air control to bring the fuel in with the air, letting the oxygen sensor adjust the fuel ratio. This provides the best mixing of the gas and air which provides excellent engine performance. The engine idles and runs the same as it does on gasoline without the intense programming and adjusting needed with sequential injection, fuel rail, conversion kits. There is more information on sequential kits below. The mixer does restrict the air flow some when running on gasoline, but not enough to effect the performance or fuel economy.
The instructions are written for the car owner to install with many tips, "how to" information and a trouble guide.

No programming is needed with our EWS kit as we have each controller programmed for your engine's requirements, but we recommend purchasing the software and the computer cable as you can fine tune it and troubleshoot it better. All you do is adjust the idle knob on the regulator while observing the 3 indicator lights on the EWS controller, which let you know the engines adjusted properly. This kit is the easiest kit to adjust and is the best choice for those not wanting to use a computer to program the controller. A USB computer cable, software instructions, and the software are available, and are recommended, and are nice to have for troubleshooting or fine tuning.

Our Millennium kit comes with software, software instructions, and a computer cable and has many more features listed below.
Both kits feature self adjusting electronics which always provides peak performance.
All our kits have a control on the dash which indicates which fuel you are using and how much CNG is in your tank.
All our kits allow you to run on either gasoline or CNG with the push of a button on the dash.
all our kits come with regulators designed for your engine size for more power and better performance.
If you run out of CNG with our EWS kit you will begin to loose power so you just push the button on the dash and you will switch to gasoline and continue driving. Our Millennium kit will automatically switch to gasoline if you run out of CNG. You should always refuel before you run out of either fuel.
Read the features of both our EWS and Millennium kits on our PRICES page to decide which kit you would prefer.

The Millennium is here!
Our new Millennium Conversion Kit is now available for all fuel injected engines. This is the best conversion kit available anywhere. Listed below are just a few features.
1. Automatic conversion to gasoline before you run out of CNG.
2. Smooth instant automatic conversion to CNG while starting on gasoline. The conversion RPM and fuel overlap are adjustable using the software to provide the smoothest and safest conversion. This is the only conversion kit that can do this.
3. Option to start on CNG if needed.
4. Adjustable aluminum mixer available in 6 sizes 1.5, 2, 2.5, 3, 3.5, and 4 inch diameters.
5. Easier fuel injector wiring with connection to the one common injector wire to turn off and on all the fuel injectors.
6. All computer controlled solid state electronics with no mechanical parts or relays.
7. No fuel injector emulators to wire and install.
8. Emergency CNG starting and operation if the engine will not operate on gasoline.
9. Has Oxygen Sensor diagnostics to warn you of any operating problems.
10. Comes with software instructions, a USB computer cable, and the software on a disk, a $50 value.
The software will not install on a 64 bit computer. We recommend using a low cost net book computer using
32 bit Windows Starter.
11. Comes with an installation and operating instructions with many tips, how to information, and a trouble guide.
12. Many other features and adjustments available using the software so any engine can be set up to operate properly.
13. The same features as our EWS mixer kit plus many other options and features.

Certification Training

They provide a 2 day course for $200 each and have been doing this for several years and they do a great job.
It is worth the trip to fly there from other states.
This course will provide you with all the information needed to study for the test to become a CSA America Inspector.
Do not go to high cost training classes by companies promoting their own products who are not trained instructors.

State by State News
California News: California now requires all CNG kits to be CARB certified or they will not pass the smog inspection.
You can install a kit, but if your vehicle needs smogged you will have to remove some or all or the kit during the inspection.
If you live in California complain to your authorities about these laws and get the laws changed!
