VP TMD 22 removal


Paul Osterberg
 

I trying to remove the Turbo for maintenance or replacement, but can't get the high pressure tube to lose. The nut is copper, key number 10 is to small an key number 11 to large. Filed a key 10 to the right size but still stuck. Tried with small blowtorch but did not helped. The copper nut is also rather soft so key/wrench is slipping. Any idea how to proceed?
