Radium Fuel Rails - GM LS Engine

Application: GM LS1, LS2, LS3, LS6, L76, L99
Part Type: Upgrade fuel rails
Part Number: 20-0232

These Radium upgrade fuel rails are manufactured with a large 0.69in (17.5mm) internal bore to support high engine power requirements. They are CNC machined from extruded 6063 aluminium, black anodised and laser etched, and are compatible with all fuel types including E85.

The end ports and lower centre ports are tapped 8AN ORB (3/4"-16 female), with the centre ports accepting optional adapters. Reversible billet mounting feet suit multiple LS engines by installing them in different threaded holes, and the 14mm ID injector bores allow factory injectors to be used.

Important Notes

• This is an upgrade rail, not a top feed conversion – OEM or OEM-equivalent injectors must be used (matching OEM injector height and upper/lower O-ring diameters and styles)
• Injector dimensions vary by engine – injectors must match the intake manifold (e.g. LS1 injectors with an LS1 manifold)
• Radium does not make injector recommendations – consult your tuner for brand and flow rate, and the injector manufacturer for a dimensionally correct part number
• Fittings, regulators, gauge adapters and pulse dampers are sold separately
