Hi all, I’m new to this so please be gentle! I have Defender 300TDi,1996 which am slowly getting round all the leaks! The one that baffles me is the o/p of the ps pump has a swaged hose to metal pipe with an O ring on the end. Although I have changed the O ring and everything is tight the metal pipe still moves and of course still seeps fluid. Any ideas or is this normal!!
