Upgrade Your Mitsubishi with the Radium Engineering Fuel Rail Plumbing Kit

If you're looking to boost your Mitsubishi's fuel system, the Radium Engineering Fuel Rail Plumbing Kit is a fantastic choice. This kit replaces the OEM 2-bolt inlet flange, which can be a bit restrictive with its 0.22" (5.7mm) orifice. Instead, you'll enjoy the benefits of four ports that come with -8AN ORB threads, providing a more efficient fuel flow.

Designed for Your Mitsubishi 4G63

This fuel rail is engineered to fit perfectly with your Mitsubishi Evolution I, II, or III, as well as the Galant VR4, Eclipse (DSM), Plymouth Laser (DSM), and Eagle Talon (DSM) models'all powered by the 4G63 engine. It reuses the three OEM mounting spacers (Mitsubishi MD095402) to keep the fuel rail thermally insulated from the intake manifold, ensuring optimal performance.

Smart Design Features

Included in the kit are phenolic washers that work with the stainless steel mounting hardware, making installation a breeze. The mounting bosses are designed to mimic the factory fuel rail, allowing you to secure the necessary cables with the OEM brackets. You'll appreciate the four threaded ports tapped for 8AN ORB, which provide versatility for your setup.

What You Need to Know About ORB Ports

When selecting fittings, make sure to choose the right ones based on your specific application and the type of hose you're using. It's essential to have enough space around the fuel rail ports for larger accessories like fuel pressure regulators, gauges, and pulse dampers. You can refer to the dimensional drawings on the product pages for guidance.

Getting the Right Fit for Your Injectors

This fuel rail features 11mm injector bores and is designed to work seamlessly with OEM fuel injectors. If you're considering aftermarket options, just ensure they match the upper and lower O-ring sizes and overall length of the OEM injectors. It's always a good idea to consult with your fuel injector manufacturer for the best fit.

Keep in mind that this option includes only the basic fuel rail, as shown in the picture below. All fittings are sold separately, making it an ideal choice for those looking to build a custom fuel system.
