Show original supplier description
The AEM Electronics High Volume Fuel Rail is engineered to support significant fuel flow for high-performance applications, capable of supporting up to 1,000 horsepower. Its 1/2-inch fuel bore design effectively dampens backpressure pulses commonly created by larger fuel injectors, while also ensuring compatibility with stock injector sizes. This fuel rail is CNC machined from billet aluminum and finished with black anodizing and laser engraving. It includes a custom fitting for the factory fuel line, and the ends are pre-tapped to accept -6 AN or 9/16”x18 fittings for users who wish to use custom fuel lines. An additional 1/8th NPT port is integrated for the installation of a nitrous setup or fuel pressure gauge. Comprehensive installation instructions, hardware, fittings, and injector O-rings are included to facilitate a straightforward installation with the factory fuel line, requiring no additional parts. The fuel rail is specifically engineered for various Honda F-series and H-series engines, including the F22A1, F22A4, F22A6, H22A1, H22A4, and H23A1. Fitment includes specific Honda Accord models from 1990-1993 and Honda Prelude models from 1992-2001. This product is manufactured and assembled in the USA.
