I am trying to install my power steering lines. They are the ones supplied with the FFR kit going onto the power steering unit supplied as an option on the FFR kit. The high pressure line fittings thread into the pump and the cylinder fine and I have tightened them as much as I dare to but the hose ends still seem to be loose. They will swivel and move in and out slightly in the socket. Obviously this is not good but I do not know what I am doing wrong and why the will not seat. Any ideas?
