Question about 1991 GMC S-15 Jimmy
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.

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...
