Our lightweight Proflow fuel rail kits fit like stock, but deliver the increased fuel volume that your Street Rod needs for maximum performance. Featuring -08AN ORB ports, the 17mm bore rail is precision CNC-machined from high-strength aluminium with a great looking polished finish. Suits a standard full length 14mm injector, while injector adapters can be used if using short or 3/4 length injectors. This kit includes all necessary fittings with Viton® O-rings for a superior seal, mounting brackets, and stainless steel hardware.
