snippet: Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide. The "conversion" fuel rails convert the OEM side feed fuel injector setup to top feed allowing the use of high flow fuel injectors (not included). The fuel rail injector bores are 14mm ID. Manufactured with a large internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from solid 6061 aluminum, black anodized, and laser engraved for a high quality surface finish. The fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85. Machined press-fit spacers are included to thermally insulate intake manifold heat transfer. The four billet injector seats are anodized and laser etched and provide a sealed receptacle for top feed fuel injectors. The seats are designed for injectors with 14mm lower O-rings. For the 20-0569-02 conversion fuel rails, adaptable mounting brackets are included that permits a wide range of Subaru vehicles to be used. Do NOT purchase "WRX Fitment" injectors.
