Radium Engineering Fuel Rail | 1989-1993 Mazda Miata (20-0769-02)

1989-1993 Mazda Miata Fuel Rail by Radium Engineering

This 0.69" big bore fuel rail is CNC machined from billet 6061 aluminum, black anodized, and laser etched for a high quality surface finish. It is a direct replacement for the OEM fuel rail. A plumbing kit is available that provides all the necessary parts to install and plumb the fuel rail with OEM components.

This kit is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM plastic spacers are reused to thermally insulate the fuel rail from the aluminum intake manifold.

If building a custom fuel setup, 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.

Like the OEM fuel rails, the injector bores are 11mm ID so factory injectors are compatible. If using aftermarket injectors, make sure they are compatible with the stock fuel rail and are the same fitment as the OEM fuel injectors (height and O-rings).

This is the basic fuel rail, and only includes the fuel rail as shown in the picture below. Factory mounting hardware is re-used (consult install instructions for more info). This is ideal for high performance applications where the installer is going to build a custom fuel system. If using the factory regulator and fuel lines, consider purchasing the plumbing kit (below).
