To get the Hydrogen into the engine I drilled a small hole into the intake manifold and inserted a short piece of break line into the hole. This give me a vacuume port.

I have been using vacuume preasure to inject both hydrogen and water
vapor at the same time. There are two aquarium stones that bubble in the electrolyzer, under vacuume preasure. This also circulates the electrolyte around the electrode and anode. [/img][/b]

OK,thats different story,because you wrote :I can get this engine to run for double the time with Hydrogen added to the gasoline.
