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 www.drive60mpg.com 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.
Cheers,

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...

    A water-fuelled car is a automobile that is claimed to use water as its fuel or produces fuel from water onboard,
    with no other energy input. Water-fuelled cars have been mentioned in
    newspapers, popular science magazines, local news coverage, and the internet
    (YouTube); at least some of the claims were found to be tied to investment frauds. This
    article focuses on vehicles which purport to extract their energy directly from
    water, a process which would violate the first and/or second law of thermodynamics

    In addition to claims of cars that run exclusively on water, there have also
    been claims that burning hydrogen or oxyhydrogen in addition to petrol or diesel
    fuel increases mileage. Around 1970, Yull Brown developed
    technology which allegedly allows cars to burn fuel more efficiently while
    improving emissions. In
    Brown's design, a hydrogen oxygen mixture (so-called "Brown's Gas") is generated
    by the electrolysis of water, and then fed into the engine through the air
    intake system. Whether the system actually improves emissions or fuel efficiency
    is debated. Similarly, Hydrogen Technology
    Applications claims to be able increase fuel efficiency by bubbling "Aquyen"
    into the fuel tank.

    A number of websites exist promoting the use of oxyhydrogen (often called
    "HHO"), selling plans for do-it-yourself electrolysers or entire kits with the
    promise of large improvements in fuel efficiency. According to a spokesman for
    the American Automobile
    Association, "All of these devices look like they could probably work for
    you, but let me tell you they don't."

1989 Jimmy S15, 3/4 350. I want to change the timing? I have added an HHO generator and need to forward the timing to get fuel saving benefits.


Loosen the bolt at the base of the distributer on the passenger's side. If you don't have a timing light, mark the dist and intake manifold so you can put it back exactly where it was in the event of a problem. Turn the dist counter-clockwise just a tiny bit and the idle should raise a little.

My heater will only blow out of the dash vents and won't move to floor or defrosters. Many have said to change the vacuum hoses. Can anybody tell me where to find them? Do I need to take apart the dash?


Heater flap works on vacum lines. My jimmy had same problem. Found out flap broke inside heater core. Gmc had a default. If something breaks it goes to defrost as safety precaution. Or a vacum leak in a hose to heater.

Looking for a vacum line diagram so i can print it 1996 gmc jimmy


GMC S10/S15/Sonoma Pick-Ups 1982-1993 Repair Manual
VACUUM DIAGRAMS (See Figures 1 through 85)

Below is a listing of vacuum diagrams for most of the engine and emissions package combinations covered by this manual. Because vacuum circuits will vary based on various engine and vehicle options, always refer first to the vehicle emission control information label, if present. Should the label be missing, or should vehicle be equipped with a different engine from the car's original equipment, refer to the diagrams below for the same or similar configuration.
Check the link autozone.com (free register), select the year ('91 sample), Brand, Model, Sub-Model, Engine Size and make the next root...

I really hope helps with this (remember rated this help). Good luck.

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.

Having a 4 low problem


A common problem for the Jimmys and the Blazers with electironic 4 wheel drive is for their to be a vacume leak in one of the lines. Try replaceing all vacume lines to any component on the 4 wheel drive. this should fix ya.

Please contact me if your problem presists.

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, hydrotuning@gmail.com, greetings, ****

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
