Stock-plumbing installs complete with the 20-0091-PK, whose green inverted flare fitting, PTFE feed hose, and ORB plugs handle the factory line interface, while custom AN systems select individual ORB fittings instead. The injector rule is Radium's standard, with flow rates from your tuner and dimensions confirmed as OEM-equivalent.
