This patent describes an apparatus for heating diesel fuel before it is filtered and for transferring heat from filtered diesel fuel to diesel fuel to be filtered, the apparatus comprising means for removably securing it between a fuel manifold and a fuel filter of a fuel supply system of a diesel-engined vehicle. The apparatus comprises: (1) an electric heater; (2) means for connecting the heater to a power supply; and (3) a housing which comprises: a heat-exchange chamber having a heat-exchange member therein and having a first entry port for the entry of filtered diesel fuel from a fuel filter when the apparatus is secured to a fuel filter, and a first exit port for the exit of fuel to a fuel manifold when the apparatus is secured to a fuel manifold; the first entry and exit ports defining a first passage therebetween on one side of the heat exchange member. The heat exchange member has a second entry port for entry of diesel fuel from a fuel manifold when the apparatus is secured to a fuel manifold and having a second exit port for the exit of fuel to a heating chamber. The second entry and exit ports define a second passage on the other side of the heat-exchange member so that heat from the first passage can be transferred to the second passage through the heat-exchange member; and a heating chamber having a heating chamber entry port for the entry of diesel fuel from the second exit port of the heat exchange means and a heating chamber exit port for the exit of diesel fuel to a filter when the apparatus is secured to a fuel filter.
