20 Leak-fuel connection
The HP fuel line is sealed by the thrust ring (8).
If leakage in the area of the thrust ring (8) or the HP line (2) occurs, the emerging fuel is routed to the leak-
age chamber.
The leak fuel is drained off without pressure via the leak-fuel transfer bore (7). The leakage chamber is sealed
by the O-rings (3).
This prevents leaking fuel from escaping.
The connection is confirmed as being SOLAS-compliant by DNV and GL.
