The rail features a large 0.69" internal diameter bore to suit even the most fuel hungry engines. They are CNC machined from extruded 6063 aluminum, media blasted, black anodized, and laser etched for a high quality surface finish. All 3 ports are machined with 8AN ORB (3/4-16 female) threads. For a list of 8AN ORB adapter fittings, go HERE. Shown below is an inline RADIUM Fuel Pressure Gauge mounted on the 8AN ORB fitting.  

Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted. This kit is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM plastic spacers are reused and Phenolic washers are included to thermally insulate the fuel rail from the aluminum intake manifold.
