With a 2-tank conversion kit you operate your diesel engine on diesel fuel while starting, shutting off and during other critical conditions. All the other time the engine runs on SVO/WVO. That means, whenever the conditions are good for burning SVO/WVO the controller gives an automatic release for SVO/WVO operation. Our 2-Tank-system is unique, because we do not use magnetic valves to control the fuel selection, we work with feeding pressure control. This will make sure, that there is always a backup on fuel and no leak of lubrication in the fuel system, which is important especially for newer and more sensitive injection systems i.e. Common Rail.
