This Radium Engineering secondary fuel rail is for the Mazda 13B-REW rotary engine.

With the use of the provided 2AN ORB plugs, this adaptable design permits both the OEM 2-port intake manifold and aftermarket 4-port intake manifolds.

The aluminum fuel rail is anodized black for compatibility with all popular fuel types including E85. Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements. The three 8AN ORB ports are compatible with these fittings. The extra center port allows additional fuel system accessories such as the OEM fuel temperature sensor, a pressure transducer, Radium fuel pulse damper, etc.

Insulating spacers and washers are included with stainless steel hardware to prevent thermal energy from conducting heat into the fuel. The two M8 extension mounts are made from stainless steel for superior strength and corrosion resistance.

For the OEM 2-port intake manifold, the included 20mm insulating spacers, billet injector seats, and 2AN ORB plugs will be used. Also, for the required space, an air control valve delete for the OEM 13B-REW intake manifold (sold separately) is required. See Radium 20-0449 HERE.

The included 14mm lower injector seats were designed specifically to be compatible with or without the OEM diffusers in place. They feature FKM O-rings making them suitable for boosted applications. NOTE: if using an Elite Rotary Shop 4-port intake manifold.

With this fuel rail, all lower intake manifolds variations are compatible with the fuel injectors listed below. For the Xcessive Manufacturing 4-port intake manifold, the included 11mm insulating spacers will be used.

Love the shelves. Nice touch to my bathroom. Easy enough to install. They're not holding anything too heavy so can't speak too much on that but they do have a nice width.

Good for light stuff
Color: Black, Size: 15 inches, Color: Black, Size: 15 inches
Good product. Very light though and if it’s in dry wall won’t hold something really heavy. I don’t think it would hold 20 pounds just light. I put over my washer and dryer and put one right on top that way I can put heavy stuff on that side without it weighing down and being ripped out of the wall. I won’t be putting heavy stuff on the right side I used 4 pieces and the wall is about 60-62 inches long

Perfect sized floating shelves
Color: Black, Size: 24 inches, Color: Black, Size: 24 inches
These are great and the perfect width. I had my contractor install them because my tile had to have a hole drilled into it. I love that it looks seemless and flat to the tile. New bathroom renovation. I am very pleased. Holds a few towels also candles and a little plant with extra space. Perfect for a minimal look or if you have a small bathroom. Color was spot on.

Not What I Expected
Color: White, Size: 32 inches
This set of floating shelves was a disappointment. They’re advertised as holding 20 pounds, but mine began to bend with barely 10 pounds on them. All the screws and anchors were installed tightly and correctly, yet the metal brackets still warped under minimal weight. The shelves look fine on the wall, but I’m leaving them up only because I don’t want to patch a dozen holes—not because they’re sturdy. Definitely not the quality or strength I expected.
