A fuel tank plumbing structure includes a first pipe; a second pipe coaxially connected to the first pipe; a flexible locking piece having a protruding end displaced in a radial direction of one of the first pipe or the second pipe; a locking portion formed in another of the first pipe or the second pipe to engage the locking piece; and a lock member annularly formed and fitted externally onto the one of the first pipe or the second pipe, and including an escape groove portion and a control wall portion arranged adjacent to the escape groove. The lock member is displaced in an axis line direction of the one of the first pipe or the second pipe between a first position wherein the locking piece is displaced toward the escape groove portion, and a second position wherein the locking piece abuts against the control wall portion.
