The cautionary tail is that the high side pressure DOES NOT bleed down when the car is shut off. Even over an extended period of time. A couple of American engineers found this out the hard way. There is a high pressure bleed down procedure using the factory scan tools. Please be careful if you attempt to work on the fuel system.
