| Racetronix Billet Aluminum Fuel Rails are the perfect upgrade for the undersized factory LS1 fuel rails. These rails have a huge 3/4" bore from end to end for unbeatable flow capability and even pressure distribution for the most demanding HP applications. ORB o-ring fittings on each end eliminate sealing and cracking problems inherent to inferior fuel rails which use NPT pipe thread fittings. An additional -8 ORB port is located on the center / underside of each rail. The mounting aluminum brackets are color matched to the fuel rails. Stainless allen-head screws and washers are provided to secure the mounting brackets to the fuel rails. The factory 5mm bolts are used / required to secure the rails to the intake manifold.
