The following instructions should be followed when disconnecting and connecting pressure lines: 

Clean contaminated line connections before disconnecting them. Seal disconnected lines and hoses and connections to components immediately with blind plugs.

Only use open box wrench and special tool when loosening and tightening pressure lines to avoid damage to the line connections.

Check the component concerned and line connections for leaks after assembly work on the suspension system.
