Radium Engineering Fuel Rails | Fits Some GM LS Engines (20-0232)

The LS aftermarket rewrote everything except, too often, the fuel rails.

The Radium Engineering Fuel Rails for GM LS Engines finish that job: CNC machined aluminum high flow rails, anodized and laser etched, with large internal bores supporting all necessary engine power requirements and ORB porting for regulators, dampers, gauges, and serious plumbing. Built for the LS configurations Radium lists, feeding everything from cammed street engines to boosted swap builds, with all fuel types including E85 welcome. Injectors and fittings sold separately.

What You'll Feel

• Fuel delivery headroom for cammed, boosted, and swapped LS builds
• Consistent injector supply across all eight ports at sustained load
• ORB ports opening dampers, gauges, and regulator options factory rails never offered
• E85 confidence from the anodized aluminum construction

Features

• High flow fuel rails for supported GM LS engines (verify your intake configuration)
• CNC machined aluminum, anodized, laser etched; large internal bore
• ORB ports for feed, crossover, and accessories
• Upgrade rails: OEM or OEM-equivalent injectors only (matching height and O-ring specs)
• All fuel types including E85; injectors and fittings sold separately

The Details

LS fitment lives at the intake manifold, not the block, with rail spacing and mounting driven by which intake the build runs, which is why Radium scopes this rail set to specific LS configurations: verify your intake against Radium's listed fitment before ordering, especially on swap builds mixing generations. Plumbing configures per the system through the ORB ports, factory-style or full AN, return or returnless per the regulator strategy. The injector rule is Radium's standard for upgrade rails, with OEM-equivalent dimensions confirmed with the injector manufacturer and flow rates from your tuner.

Kit Includes

• 2x Anodized, laser etched high flow fuel rails with mounting hardware
• Injectors and plumbing fittings NOT included
