Product Detail
Part #: SMY - FRL - RD. The standard fuel rails work well for low - power setups. But as you boost your horsepower, you need more fuel, and the stock fuel system just can't keep up. Our SMY fuel rails are crafted to offer the maximum fuel delivery and fit just like the original equipment (OEM fitment). They're made from billet 6061 aluminum and anodized in a beautiful gloss red color. With a 5/8' diameter through - hole and threads for - 8 O - Ring Boss fittings, they ensure smooth fuel flow. You can use the provided Allen head bolts or your stock hex head bolts. What makes our rails stand out is the unique slotted design. Features include an engraved SMY logo, a shiny gloss red finish, a custom slotted rail design for top - feed fuel systems, threading for - 8 O - Ring Boss fittings, made in the USA, and a lifetime warranty. Specifications: machined from billet 6061 aluminum, compatible with E85 fuel, 5/8' diameter through - hole, and threaded for - 8 O - Ring Boss fitting. Each kit comes with 1 pair of red rails, 4 stainless - steel screws, and 4 stainless - steel washers. Fitment details: 2002 - 2007 WRX (you'll need to replace side - feed injectors with top - feed injectors), 2007 STI, 2008 - 2014 WRX, 2008 - 2014 STI, 2015 - 2021 STI, and 2008 - 2012 Legacy.
Using these SMY fuel rails is straightforward. First, gather all the components in the kit - the pair of red rails, stainless - steel screws, and washers. If you're using a 2002 - 2007 WRX, make sure to replace the side - feed injectors with top - feed injectors. You can choose to use the supplied Allen head bolts or your stock hex head bolts for installation. When installing, ensure that the - 8 O - Ring Boss fittings are properly threaded. As for maintenance, since these rails are made from billet 6061 aluminum and are fuel E85 compatible, they're quite durable. But it's a good idea to periodically check the fittings for any signs of looseness. If you notice any fuel leaks or other issues, don't hesitate to reach out as these rails come with a lifetime warranty.
