20-0533-02 Fuel Rail, Mitsubishi, Early 4G63

This option includes only the basic fuel rail as shown in the picture below. All fittings must be purchased separately. This is perfect for installers building a custom fuel system.

The Radium fuel rail eliminates the OEM 2-bolt inlet flange which uses a restrictive 0.22" (5.7mm) orifice. The fuel rail reuses the 3 OEM mounting spacers (Mitsubishi MD095402) to thermally insulate the fuel rail from the intake manifold. Furthermore, thermal insulating washers are provided for the stainless steel mounting hardware. Mounting bosses mimic the factory fuel rail for securing the cable(s) that pass by with the OEM brackets.

FUEL INJECTOR COMPATIBILITY

This fuel rail is compatible with factory or OEM equivalent fuel injectors. This means that the injectors installed must match the OEM height and o-ring dimensions. If upgrading fuel injectors, consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating "OEM equivalent".

PORTS AND FITTINGS

The fuel rail features four (4) threaded ports that are tapped for 8AN ORB fittings.

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 and type of hose to be used. 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.
For any ports that are not going to be used, simply install an 8AN ORB plug (available on the 8AN ORB adapter page).

The plumbing kit includes the items in the image below and is ideal when when using the factory regulator and fuel lines. 

This kit replaces the restrictive OEM banjo bolt and runs a 6AN (3/8") hose directly from the fuel filter to the fuel rail. In addition, two FPR adapters are included to reuse either variation of the Mitsubishi OEM fuel pressure regulator. All necessary fittings are included for an easy bolt-in installation.
