PORTS AND FITTINGS
This fuel rail features three 8AN ORB ports and one 1/8NPT port.
Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.
This 1989-2002 Nissan Skyline GT-R fuel rail kit is designed specifically for OEM (R32/R33/R34) RB26DETT intake manifolds. Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. The rail is CNC machined from a custom 6063 aluminum extrusion and black anodized and laser etched for a high quality surface finish.
For thermal insulation, press-fit machined phenolic spacers and washers are included to completely isolate the fuel rail from heat transfer via the manifold and mounting bolts, as shown.
The fuel rail is designed for any aftermarket injectors that have the same fitment as the OEM injectors. Contact an injector manufacturer to see what they offer.
The upper injector bores are machined with a common 11mm ID (Denso). Use the included O-rings if re-using the OEM injectors, otherwise the included O-rings will not be needed.
The rail is compatible with all fuel types including popular alcohol mixtures such as E85.

PORT CONFIGURATIONS:
The Front, Rear, and Center Ports use 8AN ORB (3/4"-16 O-ring threads) to accept many adapter fittings for custom high flow fuel system builds. If the OEM Fuel Pressure Regulator will be reused, select the 20-0303 FPR Adapter option for the Front Port. The Gauge Port has 1/8" NPT female threads commonly used for a fuel pressure gauge/sensor or it can be plugged. Use the optional check boxes above and the diagram below to select the appropriate port configuration for your specific application.
