Show original supplier description
Constructed from billet and anodized aluminum, this fuel rail kit is built for durability and a premium look. Featuring 8AN inlet and outlet ports, the rail is highly adaptable. It includes a 1/8 NPT port on top, specifically designed for the easy installation of a fuel pressure gauge. The interchangeable fittings on all three ports offer flexibility in setup. This fuel rail kit is designed and assembled in the USA and is compatible with a range of Honda and Acura models, including the 2002-2015 Civic Si, 2002-2006 RSX, 2003-2008 TSX, and 2002-2014 CRV. It specifically supports K20, K20a, K20a2, K20z, K20z1, K20z3, K24, K24a, and K24a2 engine variants. The kit includes the fuel rail, one 6AN fitting, two 8AN plugs, one pressure gauge, and two mounting bolts. A crucial note for installation: this kit is a direct fit with the factory fuel line. If you plan to use an aftermarket fuel line, it's essential to verify the inlet adapter size, as additional fittings may be required for proper integration.
