Radium Engineering Fuel Rails - GM Vortec 8100 Big Block
These Radium Engineering fuel rails replace the factory rails on the GM Vortec 8100 (L18) 8.1L big block (SKU 20-0862). They are CNC machined from 6061 aluminium, black anodised and laser etched for a high-quality finish.
Each rail has six 8AN ORB ports (twelve in total), giving plenty of options for feed, return, regulators, pulse dampers and gauges. Matching plumbing kits are available for 2001-2003 return-style (20-1062) and 2004-2010 returnless (20-1162) vehicles.
Note: Fittings must be selected to suit your application. Larger accessories such as regulators, gauges and pulse dampers need clearance around the port, so check dimensions before ordering. Installation by a professional is recommended. Designed around the US-market vehicle; please confirm fitment on Australian-delivered vehicles with our team before ordering.
