Multiple Subaru Fitments Fuel Rail Plumbing Kits by Radium Engineering 

These plumbing kits are designed to compliment Radium Engineering Subaru EJ fuel rail installations. Both kits interface with the factory feed and return hard lines in the engine bay (near the LH strut tower) and provide all the underhood fuel plumbing. All necessary fittings and hoses are included, along with an adjustable high-flow fuel pressure regulator. Two kits are offered; one that feeds the fuel rails in series, and another that feeds the fuel rails in a parallel configuration. Both kits perform equally well. The end decision is based on personal preference. Scroll down for details on each kit.

This kit interfaces with the factory hard lines near the LH strut tower using SAE quick-connects or older hose barb connections. An adjustable Radium Direct Mount Regulator (DMR) and Radium 0-100psi fuel pressure gauge are included. The fuel pressure gauge can be installed at any of the 6AN junctions before the regulator using the included adapter. The 6AN swivel fuel rail fittings are low profile making them ideal for the tight spaces associated with the EJ motor. The variety of reuseable PushLok hose ends permit customizing (such as adding a flex-fuel sensor) making installation quick and painless. The included 6AN fuel hose can be cut with standard tools and assembled without special skills. Unlike standard low-quality rubber fuel hose that degrades with alternate fuels, the provided hose is resistant to all fuels including E85. The contents of the 20-0578 kit are shown in the photo below.

Because the hoses and fittings are consolidated, the parallel kit is a good option for cleaning up the engine bay. Each fuel rail is fed as shown in the photo above. The feed and return lines enter the Radium Multi-Port Regulator (MPR) from the rear and output through the front to the fuel rails.

Affordable, stylish and Well Crafted.
Size: XX-Large, Color: Khaki
This trench coat has quickly become my favorite wardrobe piece! Not only is it incredibly comfortable, but it’s also the perfect blend of style and functionality. The material feels soft yet durable, and it’s lightweight enough to wear throughout the day without feeling bulky. The design is simply timeless and elegant. It fits beautifully, with a tailored silhouette that flatters without being too restrictive. The details, buttons, and lapels—are thoughtfully crafted, giving it a polished, high-quality look. What truly sets this trench coat apart are the compliments I receive every time I wear it. Whether I’m at work, running errands, or heading out for dinner, people constantly ask where I got it. It’s one of those rare pieces that make you feel confident the moment you put it on. If you’re looking for a coat that combines comfort, style, and versatility, this is an absolute must-have. It’s a wardrobe staple that’s worth it.

Very nice jacket/coat for the price
Size: X-Large, Color: Black
This was purchased to wear with a tuxedo for northern winter wear. The size XL is what he normally wears. It fit well over a tux shirt, vest and jacket. The length is perfect for a man; it covers the tux but does not get tangled in knees. It is lined in a satiny fabric. The wool type material is a bit rough, not soft, but it does the job. The black is rich looking and provides warmth for really cold weather. This jacket can easily be worn for casual wear. Should only be dry cleaned, but doubt it will ever really need to be cleaned.
