One end portion of the conduit at the fuel inlet side thereof is transformed into a circular hollow section by shrinking work or enlargement work from said rectangular or square section. Within the inside of the circular hollow section a fuel inlet pipe is inserted directly or indirectly via a straight adaptor and is brazed together, whereby the fuel inlet pipe is connected in alignment with the conduit.
