Frequently Asked Questions

















































1. What is the best method for running my MagDrive HHO Generator?
We recommend running the Magdrive HHO Generator in the Hybrid Fuel Mode. Meaning using your regular fuel along with the fuel produced from the MagDrive HHO Generator. Most users achieve a 35 - 45% fuel savings average.

2. Okay, I decided to run it as a Hybrid fuel system, will I get rust or corrosion that way too?
Not really, the fossil fuel [gas or deisel] produces more than enough heat during combustion that when the HHO burns and converts back to water, the engine temps are high enough to keep it as a vapored steam until it exits the exhaust system. We have units running almost 2 years without any evidence of moisture or corrosion problems.

3. Will I get instructions to install my MagDrive HHO Generator?
On all Series 11a & 12a HHO generators it only requires 1/4 gallon of white distilled vinegar for a 2.5 - 4 amps cold start setup readings

Yes, with every unit you receive the basic installation instruction on how to install your MagDrive HHO Generator, they are also listed on our support page. That includes a simple wiring instructions and where and how to connect the HHO Generator to your engine. Any person who is mildly mechanically inclined can install the MagDrive HHO Generator. A professional mechanic could easily do the job in under 2 hours. We also have installers in some areas of the USA, Australia, New Zealand, Mexico,Brazil and Bolivia, who you can contact for your HHO generator installation.

4. I have 2 vehicles, one is fuel injected and the other is an older vehicle that's carburated. Will the HHO Generators work on both kinds of fuel systems?
Yes they do, for engines with a carburetor connect the HHO outlet venturi hose directly over the carb into the throttlebody orifice located right over the carburetor.

On fuel injected engines, connect the HHO outlet hose to the venturi into the air intake plenum as close to the throttle body assembly as possible.

5. If I have questions is there any tech support for my MagDrive HHO Generator?
Yes, you can email support@fuelfromh2o.com or call us M-F 8-5 or Saturday 10-3 1-800-866-5703.

6. Is there any kind of guarantee that comes with my MagDrive HHO Generator?
Yes there is, we guarantee that the product is free from defects and errors in workmanship and it will perform as advertized. Depending upon your vehicle and driving conditions, you can expect anywhere from 15% to 45% fuel savings [increase] over your current fuel usage. If you are not satisfied with your HHO Generator, please read our product Guarantee page linked from the main page. All assessory parts are guaranteed for 90 days from installation date. The Brick cell is guaranteed for one year from date of installation.

7. Why are your HHO Generators less expensive than the others I've seen on the internet?
We could charge more like some of the other producers on the internet, for example $750 or higher, but let's be realistic. A working man with a family of four has enough trouble making ends meet and paying the ridiculous prices for gasoline if we raise the price of HHO units, now the poor man gets stuck between a rock and a hard place and can't afford either. If we charged those high prices, we would be no different than the big oil companies. The principle idea is to make it affordable for everyone.

8. Why do I have to turn off the unit when not in use?
You are creating hydrogen and oxygen through electrolysis, during this process you create heat. If you leave the unit overnight, you WILL kill your battery's charge and over heat the unit to include boiling out all of the electrolyte.

To avoid this problem, you can connect your unit using a little gismo called an Add-A-Circuit which can be purchased at just about any auto parts store for about $5.00. What this does is make the HHO Gen turn on/off through the ignition key. So if you forget to shut it off with the Main Power Switch it will get turned off when you shut off and exit your vehicle.

The Series 11a & 12a HHO Units will operate upto 120*F without any difficulty, but through negelect by not turning it off when not in use can damage the unit by over heating it past its tolerable operating temperature limits.

9. What do I do during cold weather to protect the generator?
The HHO generators use distilled water and acetic acid as the electrolyte, commonly called distilled white vinegar (5% mix). The reservoir also has the mixed electrolyte, same as the HHO generator. Being acetic acid based, minimal freezing protection is all that's necessary. Both can freeze solid without any major problems. Once the power switch is turned on the HHO generator will immediately begin to thaw out.

If you want to have added protection against freezing:
1. Use denatured alcohol or ethyl alcohol, mix 1 part alcohol to every 5 parts vinegar
2. Insulate the circulation tank/pump and Brick cell with foam pipe wrap insulation, get it at Home Depot or Lowes.

10. What if I want to move the HHO Generator to my other car or truck?
If it's is going to be transferred over, you can get all of the necessary clamps, fittings, etc at Home Depot or Lowes. We designed the units using these readily available items in the event you broke something or lost a part during installation. All of the electrical parts can be purchase at Autozone, Advanced or O'Reillys. The only item you would have to order is the gas/liquid saftey valve, that comes from US Plastics in Lima, Ohio.

11. How far can I travel using the Auto-Fill add-on with my HHO generator before I have to refill the reservoir tank?
On the NEW Series 11a & 12a Hands Free models, you can travel appx 500-1000 miles using the electrolye in the generator and the 2 quarts in the reservoir tank before topping off with Distilled Water. Mileage would depend upon engine size and vehicle speed. You should do a system drain and flush every 5000 miles.

12. Why dont you sell units that can run the vehicle on just HHO alone without any other fuel?
Primarily beause someone would purchase a unit and install it on a vehicle without making the necessary modifications and eventually destroy their engine. They could then come back at us with a lawsuit claiming we sold them a product that destroyed their engine. It's a liability factor, people today file lawsuits for a hangnail or stubbing their toe. In a court of law we would be found at fault just because we sold such a unit knowing that the purchaser could avoid doing the modifications and just install the unit anyway. A court would declare that we didn't put in any safe guards making the unit fool proof for people trying to take short cuts.

13. Basic questions for Series 11a and 12a models
1. Current Draw: 3.5-5 amps cold...7-11 amps warmed up
2. Electrolyte: Use white distilled vinegar for your electrolyte
3. Condensation: There is always some kind of condensate residue in lines when shut down & cooled off.
4. Check Engine Light: The Check engine light has never come on once on any vehicle no matter what year, model or engine.
5. Explosive gas under hood: No, there isn't any explosive gas floating around under the hood. It's an on-demand, sealed system, not a pressurized system and works under a vacuum principle.

14. When I start to lose fuel economy and performance, what's happening and what do I do?
Loss of fuel savings and performance tells us one thing without any guess work, here is whats happening. As the electrolyte is used and new replacement electrolyte is introduced into the generator, all of the minerals and chemicals from the used electrolyte to HHO gas is left behind in the Generator. This over a period of time can build up. Thats why its very important to use good store bought white distilled vinegar. To continue, that left over build up of minerals and what ever gives the electrical current an avenue to conduct through the residue instead of the internal HHO electrolyte. Remember, that electricity will take the shortest and easiest path. Well the current is being conducted by the residue and not the internal HHO electrolyte, some symptoms will be that the unit does not get up to operating temp or the HHO production drops off and fuel economy and performance will begin or drop off gradually or almost completely if not tended to. To remedy this situation, empty and flush out the generator until you have clean flush water coming out. Then refill with white distilled vinegar [as instructed in your original instructions]. After performing this minor service your HHO generator will start to perform as it did originally. Remember maintenance is necessary to keep your MagDrive HHO generator working efficiently and up to operating temps. Like everything else, it does need to have some care and maintenance according to the use demands put upon it.

15. Do I have to make any changes to my vehicle's engine or computer?
In 95% of the installations NO computer or mechanical changes need to be made to either your vehicle or its computer. It is some time only necessary on OLDER vehicles [1985 and OLDER] to adjust the engines timing a couple of degrees and also the engines idle speed. On newer vehicles, the engines computer reads the info from the O2 sensor, Throttle position sensor and the Mass air flow sensor and then makes the necessary adjustments to the fuel/air mixture automatically.

16. What is the best location to install my HHO generator?
The most advantageous location to install a MagDrive HHO Gen is in front of the radiator or secondly in the engine compartment (under the hood). We have had some installs in the rear bed of a pickup truck and in the trunk. Those locations cause a lag time from throttle response and HHO performance lessening the efficiency of the HHO unit.

17. What is the best and most accurate method of setting up my HHO generator using the included electrolyte?
Better way to setup MagDrive HHO generators to avoid over heating problems after long periods of operation. IT ONLY TAKES 1/2 GALLON OF WHITE DISTILLED VINEGAR TO MAKE 3.5 - 5 AMPS FOR SETTING UP AND FILLING THE HHO GEN.

Keep in mind the initial charge amperage should be 3.5 - 5 amps and once warmed up, at full operating temp the amperage should be appx 7 - 11 amps. The unit has a 15 amp fuse for protection of over amperage which limits the operating temp from exceeding the maximum allowable temerature. Do not exceed the operating temp of 150*F, or alter the electrolyte mix ratio or eliminate the 15 amp protection fuse, either "WILL" result in causing a melt down on the anode post.

You must turn off the HHO gen when exiting the vehicle, if you do not it will boil out the electrolyte, drain the battery and make it difficult to re-start your engine. We strongly advise getting an ADD-A-CIRCUIT to power your HHO gen, it can be purchased at any auto supply store for appx $7.

By setting up your HHO gen in this manner, you will avoid the problem of blowing the 15 amp fuse as the operating temperature rises and also avoid the Main Gen wires from getting to hot from excessive current flow.

18. How do I service or clean out my Magdrive HHO generator?
It's a very simple process that takes about ten minutes. Just follow these instructions:
1. Turn off the unit. Remove fill and drain plugs.
2. Drain unit using drain plug located on bottom of HHO generator
3. Flush with water and allow to drain.
4. Install drain plug and fill with vinegar.
5. Turn on power, but do not start engine.
6. Add white distilled vinegar electrolyte with power turned on until proper full mark on the circulation reserve

19. I installed my generator, but fuel mileage went down!
If you install our HHO gen and the fuel mileage decreases its due to to much o2 in the engines exhaust. That causes the O2 sensor to send a signal to your vehicles computer to enrich the air/fuel ratio mix, defeating the purpose of the HHO. This problem can exist in just about any vehicle with ODB1 and ODB2 ecu controlled vehicles. Although we see this in appx 5 out of every 100 systems. Our HHO gens can produce to much HHO causing this delimma using the standard electrolye setup. To cut back on the HHO simply dilute the electrolyte, cut it in half with distilled h2o. That will lessen the o2 in the exhaust, although your mileage gains will suffer too. The better way is to get ahold of an EFIE unit we have tried several and Eagle Reseach has worked out to be the best so far on all of our test vehicles. If you have a v8 or v6 you will need two EFIE units, one for each cylinder bank. A four cylinder engine requires only 1. The EFIE units are tied into the primary o2 sensor before the catalytic converter with a simple cut and splice connection. Eagle research provided a very clear and simple to understand installation set of instructions. Using the EFIE and full HHO production we have seen results exceeding 48% increase in fuel mileage
