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.
The leaking fuel is drained off without pressure via the leak overflow bore (7). The leakage chamber is sealed
toward the outside by the O-rings (3).
This prevents leakage egress.
The union is confirmed as being SOLAS-compliant by DNV and GL.
