The factory R35 fuel rail has a restrictive boss with in the tube which interrupts the fuel flow for high power application. GReddy Fuel Delivery Tube will improve the flow capacity by straightening the main tube with the injector center line as well as increasing the inner diameter of the main tube to 14mm. We were also able to increase the inner diameter of the connecting line to each bank to 10mm by using AN8 fitting and -8 Teflon lined fuel safe hose.

- With the included flanged fittings and -8 AN fittings you can mount the factory fuel pressure regulator and the dampener right on the rail or customize with upgraded fuel pressure regulators.

- By separating the mounting bracket from the main tube, the mounting height are adjustable, keeping the original injector mounting angle.
