This big bore fuel rail features a large 0.69" diameter internal bore with 3/4"-16 female threads (-8AN O-ring port) at each end to accept a variety of adapter fittings for custom high flow fuel system builds. This is the largest S2000 fuel rail bore on the market that uses all 5 crucial OEM mounting bosses. The fuel rail is machined, anodized, and laser etched for a high quality surface finish. It is compatible with all fuel types including popular alcohol mixtures such as E85.
It is directly compatible with the 2004-2005 (AP2) OEM fuel feed banjo hose. However, if the OEM banjo hose will be reused on the 2000-2003 (AP1) S2000, Honda P/N: 16623-PCX-003 must be purchased. This is a Joint, Fuel Flange found on the AP2 fuel rail (shown below) that prevents the banjo from spinning while the bolt is torqued. Also, note the restrictive 0.21" (5.3mm) orifice of the OEM banjo flange. This fuel rail was not designed for the 06-09 Honda S2000.
