PORTS AND FITTINGS

The fuel rail ports are tapped for 8AN ORB.

8AN ORB Adapter Fittings can be found HERE.
8AN ORB Direct Mount Regulators can be found HERE.
8AN ORB Fuel Pulse Dampers can be found HERE.
Fuel Pressure Gauge Adapters can be found HERE.

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.


This fuel rail is compatible with most Mazda 1.8L DOHC BP engines:

1994-1997 Mazda Miata
1999-2005 Mazda MX-5 
1994-1996 Eunos Roadster

Installation on a 94-97 Miata shown below.

Shown below, there are provisions to support both mounting point variations. 

The rail is CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high quality surface finish.

Like the OEM fuel rails, the injector bores are 11mm 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.
