ABSTRACT:
A fuel separator is disclosed having a hollow interior in which a tubular coiled heat exchanger is positioned to receive a coolant liquid therethrough. Fuel is fed into the chamber through a fuel inlet and pumped out of the chamber by a high pressure pump into the fuel distribution system of an internal combustion engine. Heated excess fuel from the fuel distribution system of an internal combustion engine is returned to the chamber through a fuel return inlet at the bottom of the chamber and the heated fuel passes upwardly through the coolant coil thereby cooling the heated return fuel. Fuel vapor that is not condensed as a result of cooling can escape from the chamber through a float needle valve at the top of the chamber. A pressure relief valve is also provided at the top of the chamber to allow the vapor to escape when a predetermined internal pressure is reached.
