Show original supplier description
The Acuity 1913-BLK K-Series High-Flow Fuel Rail offers a versatile and refined solution for upgrading fuel delivery needs, accommodating upgraded fuel lines, or simplifying engine bay aesthetics. Its 15mm bore is capable of supporting over 1000 horsepower, making it suitable for high-performance applications. Constructed from durable 6061-T6 billet aluminum, this fuel rail features a sleek satin black anodized finish with laser-etched technical details. It boasts a 1/8 NPT port on top for a fuel pressure gauge, two -8 ORB end ports for OEM, side-feed, or return setups, and an additional -8 ORB center-feed port for tucked fuel lines. The countersunk mounting screw holes and included class 10.9 hardware ensure a clean installation, while machined end port locations help prevent cosmetic damage during assembly. The design also allows for the retention of OEM injector clips. Fitment includes most K-Series engines, with specific applications listed for 2001-2005 Civic Si and Type R, 2002-2006 Acura RSX, RSX-S, and Integra Type R, and 2012-2015 Honda Civic Si, as well as K-Swaps. However, it explicitly excludes direct-injected K20C and K20B engines. Additional fittings are required for specific applications, and the product requires PTFE thread sealant (not included).
