Hydrogen Hose Connections Hydro Super 2 Toyota Tundra 2008

Posted or updated 12.01.08 by Chuck Russell


Once you have your hydrogen generator mounted, the hose connections are very easy to do. First off, discard any Nylon hoses that came with your kit, and use only braided re-inforced 3/8 inch hosing. If given a choice of colors, opt for clear tubing so you can see the bubbler and generator working. This gives you a visual idea of how well you hydrogen generator is working, and it can be useful when traveling. Unlike nylon hoses, braided clear hose will not half close when you bend it around a corner. It won’t collapse, and it won’t sag when the weather is warm. The last thing you need is your hydrogen hose to fall across your spark plug wires, or worse yet an exhaust manifold. You also don’t want to get maximum hydrogen production from your generator, only to find out that the hose is being bottle-necked going around a corner, closing itself halfway or more, and limiting your hydrogen delivery system.

The Hydro Super 2 comes with Nylon hoses which are red and blue color. Lose them as soon as possible.. You can get very good hose at Lowes or Home Depot for about 60 cents a foot, and you shouldn’t need very much.

You need to run a hose from your water tank to the bottom of the Hydro Super 2 generator. If you have the double cell model, like I am using, you need to put a Y-splitter into the line and to feed both inputs. This Y-adapter comes with the Hydro Super 2 double cell. If you have any problems finding hose, adapters, or fittings in your area, head for the nearest pet store that handles aquarium supplies. These are the same hose and fittings used for fish aquariums.

You need to feed hydrogen into the air-intake behind the air cleaner filter. This is in the plastic duct somewhere right before the throttle body, or multi-port intake. See my picture. Drill a hole into the air intake behind the air filter, and insert your plastic 3/8 inch bent elbow. Use a bit of silicon after you insert the elbow to prevent leaks. See my picture, the plastic elbow hydrogen input is right behind the air cleaning filter, in the main plastic duct feeding the multi-port fuel injection. I have my elbow as close to the multi-port fuel injection as possible. This gets the maximum amount of hydrogen into the engine, and keeps loss to a minimum.

My second connection is to the intake manifold. The Hydro Super 2 instructions call for one connection to the air intake only. This does not address the vehicle sitting at stop signs or red lights however. If you want the maximum amount of MPG gains, and you want your vehicle to run as efficient as possible, connect the hydrogen input to the intake manifold, as well as the air intake. When a vehicle is idling the intake manifold is pulling vacumn and the hydrogen gas is being sucked in. The air intake is not pulling vacumn at idle so there is no hydrogen input there. However, when you are moving the opposite is true. The air intake is pulling vacumn, thus the hydrogen gas is going there. The intake manifold slowly loses vacumn as you start moving and accelerate, and it stops pulling hydrogen as the air intake takes over. Feeding both from the same line, keeps hydrogen going into the engine all the time. Keep your hoses as short as possible to get maximum delivery.

Insert a 3/8 inch plastic tee into the intake manifold line. Also put a 3/8 inch plastic tee between the hydrogen feed to the air intake. Then connect another piece of hose so that both hoses are being fed hydrogen. One or the other, and in some cases both will be pulling hydrogen. See my picture.  Once you have theses hoses in place, you are ready to test the hydrogen system and the vehicle. Maximum gains will only occur later when you place a MAS or MAP sensor enhancer on the vehicle. But you should already be seeing 20-30% gains just running hydrogen and gasoline at the same time.

If you have any doubt as to where your intake manifold is, then look for the PCV valve. It will almost always connect directly to the intake manifold.
