A self-contained fuel oil heater unit is described for use with a diesel engine, the unit including a fuel oil manifold and a spin-on cartridge type fuel oil filter attached thereto. The filter includes an end having a central fuel oil outlet and peripheral fuel oil inlets, the fuel oil manifold having a first portion formed with horizontally disposed fuel oil inlet and outlet passages, a second manifold portion projecting upwardly from the first portion as an extension thereof, the second portion of the manifold being formed with an upwardly open bowl shaped recess in the top surface thereby constituting a fuel oil reservoir integral with the manifold, a removable cover closing the recess, an electrically operative heater element positioned in the recess, and adapted to be immersed in the fuel oil in the reservoir for warming the fuel oil, the fuel inlet and outlet passages each communicating respectively with other passages in the manifold connected to an inlet to the reservoir and to the outlet of the fuel filter. A further fuel outlet is in the manifold for conducting the warmed fuel oil from the reservoir through the manifold first portion to the peripheral fuel oil inlets on the end of the fuel oil filter for flow through the peripheral edges thereof into the filter proper and out through the filter outlet to the fuel oil outlet passage, and means connecting the heating element to the electrical system of a diesel engine to be operative upon the engine being rendered operative.
