ABSTRACT OF THE DISCLOSURE A fuel delivery system particularly useful for supplying petroleum distillate fuels to a fuel combustions device is described. When such device is operated in cold ambient conditions, fuel clogging car. occur in the fuel supply lines. In the past, attempts overcome such problems have been directed toward applying heat to the portions of the condiut subject to restrictions or by introducing solvents into the fuel. These steps are, however, unsatisfactory. In accordance with this invention, the fuel supply conduits are drained of fuel upon shut-down of the associated engine or other fuel fired device. Upon an engine start-up command, a small quantity of fuel is warmed, preferably using an electric immersion type heater. Once a sufficient fuel temperature is reached, the fuel conduits are reprimed with fuel. Since the fuel does not cold soak in these conduits, fuel clogging problem are eliminated. Various methods for venting the fuel supply conduit enabling such pirging and priming is described.
