Dosing structure 30 is provided for supplying diesel fuel to an exhaust passage 12 of a diesel system. The dosing structure includes an electrically operated control valve 31 constructed and arranged to receive a supply of diesel fuel. A dosing valve 32 is constructed and arranged to receive fuel from the control valve and deliver the fuel to the exhaust passage. An extension tube 48 is fluidly coupled between the control valve and the dosing valve to space the control valve from the dosing valve and to permit fuel to be delivered from the control valve, through the extension tube, and to the dosing valve.
