When working with a high quality gravity fed HHO system, it is important to make sure you have a nice straight drop from your Electrolyte reservoir down to your HHO Cell. A good gauge would be from 12-14 inches will do for a single cell system, and 14-16 for a dual cell system.

If you are unable to mount your HHO Cell in this fashion there are a few other options to keep your cells circulating optimally.

By installing a small water pump you can insure your HHO cell will continuously circulate and produce quality HHO, while keeping your cell cleaner.

For configurations where the distance from the tank to the cell are less than the suggested drop ( under 12 inches)

I recommend using a smaller pump like the one picture HERE


This Pump pushes 3.8 /LMP

This is a high temperature (up to 105′C) FDA Food grade mini submersible water pump.   The shaft is coated with a layer of ZrO2 (zirconium oxide ) for higher temperature handling and better tolerance for acid and alkaline. It’s built by a brushless motor providing smooth and quiet operation than a non-brushless water pump. Plus,it will not generate ‘electric spark’ like what a brush type does so it’s more safe. It can be used to pump oil as well (no gasoline*)

For configurations where the distance from the tank to the cell are greater than the suggested drop ( over 12-16 inches) I recommend using a larger pump.


This Pump Pushes 7/LPM

This will ensure your pump is the correct size and working at the best LPM for your setup.

Below are a few pictures of a dual HHO cell setup from HydroclubUSA installed on a 2007 Chevy Silverado 5.3L with a Pump installed for better circluation.

You can find great quality pumps HERE at one of my recommended suppliers.  HHO PUMPS FROM LIGHT OBJECT


!Remember! Always mount your water pump far from the heat of the engine. Failing to do so could potentially result in the melting of your pump. I have seen it happen before so just be aware and mount it in a nice place in front of the radiator or far from the heat :-)

    • The pump will have two places to connect, an inlet and an outlet, you want the outlet to be connected to your hoses so that it is pushing water into the lower inlet of your hho cell. I can also give you a little diagram for this as well :
