Summary:A fuel delivery apparatus for an auxiliary vehicle heater includes a burner with a fuel nozzle. A fuel pump has an intake port and a discharge port. There is a first fuel conduit connected to the intake port. A second fuel conduit connects the discharge port to the nozzle. A third fuel conduit extends between the discharge port and the intake port. A pressure release relief valve is operatively disposed along the third conduit. Fuel from the discharge port is recirculated back to the intake port when pressure of fuel supplied to the nozzle through the second conduit exceeds a preset amount. Preferably the fuel nozzle is an air aspirated fuel nozzle and the fuel pump is a gear pump. The third conduit may be internal to the fuel pump.
