An engine fuel cooling system for vehicles exchanges heat between fuel and a flow of cold liquid in a coaxial fuel rail. The coaxial fuel rails include an inner fuel path through an inner tube surrounded by an outer cold liquid path through an outer tube, to cool the fuel provided to fuel injectors. The inner tube has no substantial direct contact with the outer tube to prevent external heat from being conducted to the inner tube. In one embodiment, the inner tube is solely supported by an fuel inlet fitting and injector hats teaching through the outer tube and into the inner tube. The coaxial fuel rail may be constructed using dip soldering.
