Like the original rail the injector bores are \u003cstrong\u003e14mm ID\u003c\/strong\u003e, so factory injectors carry over, and provisions for the OEM injector retaining clips are built in. Four 8AN ORB ports open the door to proper AN plumbing, and thermal insulating spacers and washers are included to isolate the rail from the cylinder head.

Radium does not make injector recommendations, so consult your tuner for flow rate and the injector manufacturer for a part number with the correct dimensions.\u003c\/p\u003e\n\u003cp\u003eThe plumbing kit supplies the 8AN ORB plugs and SAE fitting that make the rail a straight swap for the OEM part. Note that the included fittings must be arranged differently depending on whether you are on an MZR or a Duratec; Radium's instructions show both layouts, and getting it right is what allows the OEM fuel line to connect.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003e20-1303 sensor adapter is only relevant to early Ford models\u003c\/strong\u003e that had a Bosch fuel pressure sensor mounted to the OEM rail, specifically \u003cstrong\u003e05-09 Focus and 05-08 Escape\u003c\/strong\u003e. Radium notes this sensor is not common on Duratec and MZR engines, so most buyers will not need it.
