John Dow Diesel Carry tanks are designed to transport and transfer diesel fuel wherever it's needed. These tanks provide the convenience of having a refueling station that goes wherever the job requires diesel fuel. Great for farm, construction, recreation, industrial, fleet and other markets. These self-contained tanks come complete with a 12 volt pump, hose and automatic nozzle. Just hook-up to a 12 volt power source and start pumping. Strap the Carry tank to a vehicle for transport or leave it in a convenient spot on site. For vehicles requiring diesel exhaust fluid the 106-gallon Carry tank can be equipped with a separate DEF 10-gallon dispensing tank.
