The professional high speed automatic diesel nozzle is design for large fuelling applications, for vehicles with large diesel tanks. The nozzle is capable of dispensing diesel fuel and biodiesel up to B30, at a flow rate between 80 - 140L/min. As with all of our automatic nozzles, once the vehicle tank is full, the professional high speed automatic diesel nozzle will shut off the flow of fuel, avoiding an over fill or spillage. For quality purposes it has been fully wet tested. This nozzle cannot be used on gravity feed systems, and will only work with pumps outputting 80 - 140L/min.
