<p>A double-walled fuel supply pipe element (110, 120) configured to be used in a fuel supply pipe system (100) of an internal combustion engine (1) is disclosed. Local leakage detection in fuel supply pipe systems (100) can be extensive. The disclosed double-walled fuel supply pipe element (110, 120) may have an inner pipe (111, 121) and an outer pipe (112, 122) defining a leakage detection space (113, 123) there between, the leakage detection space (113, 123) being connected to the outside of double-walled fuel supply pipe element (110, 120) via a pipe element leakage detection opening (117, 126) formed in one on the end faces (115, 116, 124, 125) of the double-walled fuel supply pipe element (110, 120).</p> |
