I have a 99 F350 with a diesel engine (7.3) because of were I live mount the unit under the hood or in the grill would not work, Is there a problem mounting the unit in the bed of my truck it is covered and I have access to the bed thanks Chris
I would recommend you installing your battery in your F350 truck bed instead of the hydrogen generator. You will need to run a 2 gauge wire to your battery, which is not going to be cheap.
Then you can place your HHO generator where your battery is. If you can't do this, make sure your "covered bed" is ventilated and you wire your hydrogen generator to be on only when the ENGINE IS RUNNING.
