It arrives with the vehicle-specific mounting hardware required for a complete swap, and Dorman’s material-hardening process increases resistance to the high pressures and heat found in modern fuel systems. Before ordering, use your vehicle’s make, model and trim in the garage tool to verify compatibility.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this fuel injector line fit my vehicle?\u003c\/h3\u003e\n\u003cp\u003eThe 904-966 is manufactured to mirror the original equipment geometry and mounting points so it installs without modification on compatible models.
