Vehicle Application: 00-05 S2000 (AP1)
This big bore fuel rail features a large 0.69" diameter internal bore with three -8AN O-ring ports (3/4"-16 female threads) 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 04-05 (AP2) OEM fuel feed banjo hose. However, if the OEM banjo hose will be reused on the 00-03 (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 kit eliminates the OEM fuel rail cover and also replaces the air pump system hard tubes with vacuum hose for a cleaner appearance.
20-0091-02 Fuel Rail Kit
This setup is great if the OEM banjo fuel feed line is going to be reused. It just requires three -8AN ORB fittings (of your choice) for the front, rear, and top ports. Consider a gauge and/or a pulse damper, described below. Replacement vacuum tubing is included to simplify and eliminate the hard lines.
-Billet anodized aluminum fuel rail
-Banjo block-off plate w/ O-ring
-Stainless steel hardware

The 23" high quality PTFE hose is compatible with E85, ethanol, alcohol, gasoline, etc. The included billet block-off plate will be used to cap the stock banjo feed port. Nothing else is required for this kit.
