There could be residual pressure in the rail and you dont want a jet penetrating your skin or eyes but I just put a rag over one of union nuts and slacken it off, normally just a dribble will come out, I wouldnt do it with the engine running. You can see the rail pressure drop very quickly ( within a few seconds ) in Vida when you switch off the engine. So far have not needed to use new pipes on injectors/pump and no leaks.
