Consistent fuel delivery becomes increasingly important as injector size and engine output rise. The Tomei Fuel Rail (part number TB511A-NS05B) is a Denso-style billet aluminum rail designed for the Nissan RB26DETT, providing increased internal volume and more stable fuel distribution when running larger aftermarket injectors.
Machined from billet aluminum and finished in a durable blue anodize, the rail offers good heat dissipation to help limit fuel temperature rise and percolation under demanding conditions. The larger internal capacity supports even fuel supply across all six cylinders, while the 10.90 mm injector bores are sized for common Denso-style top-feed injectors. AN fittings are included to simplify integration into performance fuel systems.
This fuel rail is a practical upgrade for RB26DETT builds moving beyond stock injectors and seeking more reliable high-flow fuel delivery. At Terra Firma Automotive, we supply this genuine Tomei Denso-Style Fuel Rail as a clean, functional component for Skyline GT-R and other RB26 performance projects. Whether the engine is being prepared for increased boost or higher horsepower targets, this rail delivers the construction quality and flow capacity associated with Tomei. Choose Terra Firma Automotive for authentic Japanese fuel system components that support consistent RB26 fueling.
