Their fuel rails are machined from billet aluminium to tight tolerances, ensuring correct injector fit, mounting alignment, and port geometry for each supported engine. The VR6 rail is engineered to the 2.8L 24V’s injector pattern and mounting boss locations for a direct bolt-on replacement of the OEM fuel rail.\u003c\/p\u003e\n\n\u003ch3\u003e8AN ORB Ports — Fuel Line Connection\u003c\/h3\u003e\n\u003cp\u003eBoth ends of the 20-0878 feature 8AN ORB (O-Ring Boss) ports:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e8AN line size:\u003c\/strong\u003e 8AN (1\/2\" line OD) is the appropriate flow capacity for a modified 2.8L VR6 running upgraded injectors or alternative fuels.
