PORTS AND FITTINGS
The three large fuel rail ports are tapped for 8AN ORB.
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 large bore fuel rail features a large 0.69" diameter internal bore.
The fuel rail is machined, anodized, and laser etched for a high quality surface finish.
As depicted, it features billet aluminum mounting feet with stainless steel hardware.
There are three 8AN ORB machined ports for ancillary accessories.
It is compatible with all fuel types including popular alcohol mixtures such as E85.
