The leak pipe (K 70006) fitted to the fuel transfer pump K 74100 on the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 serves as a safety and housekeeping feature: it routes seepage, drips and relief flow away from the pump housing to a safe collection or return point, preventing fuel accumulation around hot or rotating parts. Built and routed to resist vibration and corrosion, the pipe helps operators detect leaks early, simplifies containment during service, and reduces fire and contamination risk — a small part that materially improves system safety and maintainability.
