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.

Manufactured with a large 0.69" internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high quality surface finish. All end ports are machined with 8AN ORB (3/4-16 female) threads. The lower center ports can be used for optional adapters and are also tapped with 8AN ORB (3/4-16 female) threads. For a list of 8AN ORB adapter fittings, go HERE.
