Show original supplier description
The ZCar Depot Billet Fuel Rail is a direct replacement fuel rail engineered for Datsun 280Z and 280ZX vehicles manufactured between 1975 and 1983. This fuel rail features a 1/2 inch inner diameter and is constructed from billet aluminum, providing durability and a clean aesthetic. It comes complete with billet mounting brackets and stainless steel hardware for a secure installation. The fuel rail is designed with 6AN ORB threads for both the fuel inlet and outlet connections, offering flexibility for various fuel system setups. Customers can choose between two styles: a stock injector style that includes barbed fittings for the fuel lines, or an O-ring injector style that accommodates 14mm O-rings for a tighter seal. It is important to note that aluminum fuel rails may exhibit minor scuffs or scrapes resulting from the manufacturing process. Separate components are available for specific connection needs, including an 800-1499 adapter for 5/16" barb fittings, an 800-648 adapter for 6AN fittings, and a 650-271 injector adapter.
