GReddy 10.5mm Fuel Delivery Rail/Tube In Black For Nissan RB26DETT 13923081

RB26DETT engines in the R32, R33, and R34 GT-R benefit greatly from upgraded fuel delivery when running larger injectors or higher power levels. The GReddy 10.5mm Fuel Delivery Rail/Tube in black (13923081) is a high-quality upgrade that replaces the factory rail with a precision-machined aluminum tube designed for six 10.5mm top-feed injectors. The anodized black finish adds a sleek, professional look to the engine bay while the 18.5mm inner diameter ensures excellent fuel flow and consistent pressure across all cylinders.

This rail features a versatile union setup that allows fuel to be supplied from both ends, with the return fitting connected to the center for optimal distribution. The included unions (AN6 x 3, AN8 x 1, and plug union) and M20 attachment screws make installation straightforward and compatible with a wide range of fuel system configurations. This design minimizes pressure drop and supports the high fuel demands of upgraded turbo and injector setups, helping maintain stable fuel pressure under hard acceleration and high boost.
