AN-8 6061-T6 aluminum hi-flow fuel rail extrusion for the fabrication of custom fuel injection systems. The 5/8" diameter fuel passage provides the flow capacity for high horsepower applications and the volume to dampen fuel pressure oscillations. The extrusion is sizeed to be machined for an AN-8 o-ring sealed fitting port. 6061-T6 material machines easily, can be welded, and can be anodized to a beautiful finish. The generous fuel injector/mounting lug can be machined for a variey of fuel injector and mounting configurations.
