Vacuum Line vs Air Intake

[Hawaiian]

Just wondering what everyones take on inducting HHO to the Vacuum Line vs Air Intake. What are your experiences what works better inducting HHO direct to Vac line or to the air intake. If you are using the air intake method where are you placing your inlet valve at? Thank you for the feed back guys!

I strongly recommend not using vacuum. It can drain your generator and worst case it could hydro-lock your engine. I installed a threaded nipple in to my air cleaner housing right next to the throttle plate.

I have heard of several people having the same problem as Eltonbrandd said.
Just drill you a hole in the hose going in to the breather and install it there.

So far I have only achieved a modest increase of 3-4mpg increase, which is a lot when I was only getting 13mpg to begin. I need to increase my total amount of gas, then lean out the engine.
