CONNECTIONS AND FITTINGS

The fuel line connections are designed for 8AN ORB.

8AN ORB adapter fittings.
8AN ORB direct mount controller.
8AN ORB fuel impulse dampener.
Adapter for fuel pressure gauges.

Appropriate fittings must be selected for the specific application. Adequate clearance around the fuel line connector(s) is required for larger accessories such as fuel pressure regulators, fuel pressure gauges and fuel impulse dampeners. To check the clearance, the dimensional drawings on the product pages can be used as a guide.

Radium Engineering High Flow Secondary Fuel Line is designed for the OEM Mazda 20B-REW rotary engine lower intake manifold. The aluminum fuel rail is black anodized and is compatible with all common fuel types including E85. The fuel line is designed with a large inner bore and can meet all the necessary engine performance needs. The additional center port allows for additional fuel system accessories such as the OEM fuel temperature sensor (using 14-0421, see below), a pressure transducer, radium fuel impulse dampeners, etc.

Like the stock fuel system, the system features 11mm injector bores, allowing the use of OEM fuel injectors (see below).

When using the supplied 14mm lower injector seats and insulating phenolic spacers, aftermarket Bosch EV14 style injectors can be used (see below).

The injector seats have been designed to be compatible with or without the existing OEM diffusers. They feature FKM O-rings making them suitable for heavy-duty applications.
