300TDI clutch pipe leak

Hello, I'm in the process of a rebuild and engine swap(300tdi going in). When I got the eng/gearbox I noticed that the clutch flexi on the 300tdi was going straight into the slave cylinder. This joint is leaking badly so I'm wondering if this setup is wrong and I need a metal pipe in between the flexi and the slave ( NRC9595 )?

This is the pipe that is going directly into the slave : http://www.paddockspares.com/ntc9055-clutch-hose-300tdi.html and it's the joint on the left in the picture that is going into the slave cylinder and is leaking. Thanks

The steel pipe will have flared ends which will 'form' as the joint is tightened to match the cylinder, I the flexi ends will be too hard to do that so that wont help things

Have a look at a parts diagram, but on 200tdi at least i used nrc9595, that goes between the slave and a bracket, which the flexi goes through and up to the bracket on passenger footwell. it's then piping to the clutch master
