20 Leak fuel connection
The HP fuel line is sealed by the thrust ring (8).
In case of leakage around the thrust ring (8) or the HP line (5) fuel escapes into the leakage chamber.
Leak fuel is allowed to escape without pressure via the leakage overflow bore (7). The leakage chamber is
sealed toward the outside by the O-rings (3).
This prevents leaking fuel from escaping.
The union is confirmed as being SOLAS-compliant by DNV and GL.
