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.
The kit features specifically designed billet mounts. These modular "feet" allow compatibility on the following GM LS engines by simply flipping them and reinstalling into different threaded holes on the rails: LS1, LS2, LS3, LS6, L76, L99 Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted. This kit is compatible with all fuel types including popular alcohol mixtures such as E85.
