It's worth to install a kit like that one from L2Hybrids. See
for the details - it's, probably, the most complete kit ever as of today, while it's not cheap.

SOURCE: hho generator

Do not use the vacuum line of the brake system!!! You need to use the vacuum line of the crank case and as close as possible towards the intake system.
I bought my hho system at and I installed in my GMC suburban. Original my suburban just got 17 mpg, since I installed the hho generator and a very good display EFIE, I am getting 24 miles per gallon. But people say it wouldn't work... well it looks like my car doesn't care what people say. ;-)
By the way, I am now installing hho generators for them. So if you need more info, let me know. That's realy cool stuff.

SOURCE: trying to change the time on the clock

Do you mean the original clock on the dash?
if that is all you have to do is: use a pointed pen to press the hour, then the minute. Better still simply press the 'set' button before you adjust the clock.

HHO does not work. The amount of air the engine sucks in throughout the RPM range is far beyond what any HHO setup can produce. You will lose power and gas mileage because the HHO system pulls energy away from the ignition spark.

2003 impala 3.4 liter wouldn't start. Cleaned terminals, installed new battery. Now after warming up battery light, service engine soon light and security light come on alternating for 3 seconds each. Also...

Could be the alternator , you can have it checked free at most auto part stores . Have them check for DTC'S diagnostic trouble codes as well . The charging system is controlled by the PCM - engine computer , if it see's a problem it will set a DTC and have the insturment cluster turn on the battery light. Plus the way the radio is acting ,it's loosing power .
DTC B1327
The body control module (BCM) determines battery positive voltage through the 10A Cluster/BCM fuse input. The BCM then sends a class 2 serial data message containing the measured battery voltage value. The vehicle control interface module (VCIM/OnStarĀ®) module monitors this class 2 message to determine vehicle voltage.
DTC P0560
The PCM monitors the system voltage to make sure that the voltage stays within the proper range. Damage to components, and incorrect data input can occur when the voltage is out of range. The PCM monitors the system voltage over an extended length of time. If the PCM detects a system voltage outside an expected range for the calibrated length of time, DTC P0560 will set.
DTC P0620
The powertrain control module (PCM) uses the generator turn on signal circuit to control the generator. A high side driver within the PCM allows the PCM to turn the generator ON and OFF. When Generator operation is desired, the PCM sends a 5 volt signal to the voltage regulator via the generator turn on signal circuit. This causes the voltage regulator to begin controlling the generator field circuit. Once the Generator is enabled by the PCM, the voltage regulator controls generator output independently of the PCM by monitoring the battery positive voltage sense circuit. Under certain operating conditions, the PCM can turn Off the generator by turning OFF the 5 volt signal on the generator turn on signal circuit. The PCM has fault detection circuitry which monitors the state of the generator turn on signal circuit. If the fault detection circuit senses a voltage other than what is expected, this DTC will set. The voltage regulator also contains fault detection circuitry. If the regulator detects a problem, the regulator will ground the generator turn on signal circuit, pulling the voltage low. This also causes the PCM to set the DTC.
When this DTC sets, the PCM sends a class 2 serial data message to the IPC illuminating the Charge indicator lamp.

Or it may be more wise to have a qualified repair shop check it out .

Is there any economical feasibility for brown gas generators ?

Yes, they do produce hydrogen and are easy enough to make.
Newer EFI vehicles with oxygen sensors located at intake as well as exhaust, have to be manipulated to get the full effect of your HHO production... that was a little trickier. I made a pot switchbox to trick the sensor signal to my engine's computer.
An older vehicle with a carburator is another matter... direct HHO into the intake.
Does it increase fuel efficiency? Yes. Any combustable added is gained effeciency.
How much efficiency, is to be determined by your car's performance and your driving habits.
Youtube has some good videos and how-to info if you're interested.
Is it worth "buying" this info? I wouldn't...
I think it should be free! We all want a greener planet.

My HHO generator draws too many amps, how do i get the amps down?

1st thing to check is the electrolyte: Use white vinegar, NOT baking soda or lye. Use a minimum of 12 ga wire on all connections, and power the generator through a relay using a 30A fuse to feed a 40A relay.Install a Tap-a-line connector from the radio circuit of the fuse panel to the toggle switch, then run a 14ga wire from the toggle switch to the relay. Doing this ensures that the generator is energized ON LY when the ignition switch is turned on. The 12ga feed wire to the relay should connect directly to the positive terminal on the battery. The 14ga wire from the switch is used only to activate the relay. This way the relay carries the amperage to the generator, and it does not pass through the switch. If the amperage is still too high, use less vinegar and use more steam distilled water to lessen the concentration, therefore lowering the amperage draw. All the parts required for this hook-up can be obtained at AutoZone, Oreilly's, etc. Good luck.

Hho no mpg increase on turbo diesel

Hi, try to hook up the hho gas hose into a vacuum line of the crank case (with t-connector) NOT directly b4 the turbo. That might help. Its not getting enough vacuum to "pull" the gas from the cell. How much hho production do you get right now? Greetings, ****

Please do some research before bothering with this bogus junk.  I am familiar with its generation and you cannot fit a generator under any hood that will produce enough gas to change your engine characteristics.
Take some time and look at the EPA's results with any of the claimed results for various gadgets:
EPA Fuel Saver reports  
Also, if you had a product to sell, wouldn't you be tempted to plant favorable 'test reports' all over the Internet?

HHO generator wiring

the hho generator power and ground does not go to the maf sensor. what you need is a maf /map regulator, but it has no connection with the generator. it is just helpfull by saving gas if a hho generator is installed. If you have o2 sensors in the exhaust pipe, you need a EFIE first!!! more questions, no problem,, greetings, ****

depending on what system you go with the tanks are large and take up alot of space.
the water for fuel idea using the alt to make HHO doesnt make enought HHO to make a difference in your millage.

Hho generator

dont waste you time try to get your money back . ive worked with many of these and not a single one has made any difference. the volume of hydrogen that the generator produces isnt enough to help in fuel millage the alternator on your car cant put out the amperage required to make the quanty needed. alot of scams going on on this stuff right now. just watch your dollar. but since you have it you might as well try it and find out for yourself. i ssen them in the pcv line T in. and ive also see them just tapped into the air cleaner just above the throttle body. good luck and let me know if it works any better for you...

Intake manifold vacume hoses

Be Sure your plans are designed for the right engine- 3.0 / 4.0 or even the smaller 4 cyls. The intake hose routing is different between engines. Make sure you do not have any EVAP system problems, this will cause your water for fuel generator to run problematic, meaning your engine may not be receiving the proper fuel/return pressure it needs causing an overtemp situation on your heads. good luck
