Radium Engineering Nissan Silvia SR20DET Fuel Rail Kit - S13

• Nissan S13 240SX SR20DET

While this fuel rail kit is designed for the Nissan S13 SR20DET (RWD configuration) intake manifold, it will also work on some aftermarket intake manifolds that use the OEM fuel rail. For the SR20VE fuel rail, click HERE.

This CNC machined fuel rail for the Nissan SR20DET features a large 0.69 inch internal bore and high flow ports that accept a wide variety of adapter fittings to suit any custom installation. The black satin anodized finish makes it safe to use with all blends of gasoline and alcohol fuels. It installs to the factory fuel rail mounting points and uses aftermarket top-feed fuel injectors.

This fuel rail features 3 large threaded ports (ends and one on the bottom) that are -8AN ORB female. It also has a 1/8NPT female port on the top.

8AN ORB Adapter Fittings can be found HERE
8AN ORB Direct Mount Regulators can be found HERE
1/8 NPT Adapter Fittings 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 features an extra 8AN ORB port in the center on the bottom. This can be used as a location for a Radium FPD-R fuel pulse damper (P/N 20-0776), as shown below. Fuel pulse dampers can be found HERE. Or this port can be plugged.
