Radium S2000 Billet Fuel Rail Kit - 00-05 S2000
Radium Engineering's 00-05 S2000 billet 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.

The Radium fuel rail is compatible with the OEM fuel pressure regulator. Alternatively, if an aftermarket remotely mounted regulator is used, the FPR port can be plugged with an 1/8" NPT plug or a fuel pressure sensor or gauge (shown) can be installed in its place.

This fuel rail was not designed for the 06-09 Honda S2000 (coming soon tho!). 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 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.

Alternatively, a block-off plate with stainless steel hardware and O-ring is included if the OEM hose is to be replaced with a high flow hose.This kit eliminates the OEM fuel rail cover and also replaces the air pump system hard tubes with vacuum hose for a cleaner appearance.

The full kit with PTFE hose also includes a special inverted flare adapter fitting that will convert the OEM hard line flare fitting to a -6AN connection. The surface finish is type-II "radium green" anodized to resist all fuel types including methanol, ethanol, and E85.
