A plurality of vent holes are spaced along the length of the body and communicated with the passage. The vent holes are sloped

Apparatus for condensing return fuel in a fuel tank. The condenser comprises an elongated body having a passage therethrough in fluid communication with a fuel return line. A plurality of vent holes are spaced along the length of the body and communicated with the passage. The vent holes are sloped along the length of the passage so that gaseous fuel will tend to first exit vent holes toward a distal end of the passage. Both single and multiple passage condensers are disclosed.
