What you are looking at there is just a part of the clutch hydraulics system. That's the tip of the pip that leads from the clutch master cylinder to the rubber pipe to the clutch slave cylinder. It is entirely POSSIBLE that the delay valve is hidden somewhere in there, but if so then the delay valve is impossible to remove unless you physically drill through it.
However it is unlikely that is where the valve is located, since the clutch line THREADS into that contraption, and if the valve is located there then it means the valve would be delaying the fluids feeding into the clutch hydraulics, not the return of the fluid and you'd get the opposite effect, delay in DISENGAGEMENT of the clutch, not the engagement of the clutch...Worst of all combinations.
The clutch delay valve is either built into the clutch slave cylinder or it doesn't exist on none Xi models.
