Show original supplier description

Constructed from durable 6061-T6 billet aluminum with a satin black anodized finish, this rail boasts a 15mm bore capable of supporting over 1000 horsepower, making it suitable for high-performance applications. Versatility is a key feature, with a 1/8 NPT port on top for fuel pressure gauges, a central -8 ORB port for tucked fuel lines, and -8 ORB ports on both ends that accommodate OEM, side-feed, or return setups. The rail includes class 10.9 zinc-plated mounting hardware and a stainless steel 1/8 NPT plug for gauge installation. Its design also retains OEM injector clips for enhanced reliability. ACUiTY offers six unique fittings (sold separately) to customize the rail to specific needs, including plug, -6AN, -8AN, and quick-disconnect adapters. The fuel rail fits most K-Series engines, with the exception of direct-injected K20C and K20B engines. Detailed fitting requirements and compatibility lists are provided for various Honda and Acura models, including the 2001-2005 Civic Si/Type R, 2002-2006 RSX/Integra Type R, 2012-2015 Civic Si, 2006-2011 Civic Si/Type R, and various K-Swap applications. Installation guides are available online.
