Show original supplier description
The K-Tuned K Series Fuel Line Kit (KTD-KSG-BLK) is engineered for 2012-2015 Honda Civic Si models equipped with the stock intake manifold and a returnless-style fuel system. This kit provides a comprehensive solution to replace the factory rubber fuel line, running from the firewall all the way to the fuel rail, for a cleaner engine bay aesthetic. The fuel feed line utilizes special EFI fittings at all connections. The system begins with a female EFI fuel adapter at the firewall, converting the factory hardline to a standard 6AN male fitting. This adapter is secured with a threaded aluminum locking clip for a leak-free connection. K-Tuned offers two layout options: a standard side inlet that connects to the left side of the fuel rail, or a center feed inlet that offers a more tucked appearance by routing the line partially under the intake manifold before connecting to the center port of a K-Tuned fuel rail. Important compatibility notes: This specific configuration is for side feed applications ONLY. If you are using a K-Tuned fuel rail with a center mount gauge setup, only the side inlet fuel line is compatible. When purchasing only the fuel lines, the 6AN wrench is not included; only the braided line and EFI fitting will be provided.
