Description
Radium Fuel Rail - Toyota 3S-GE / 3S-GTE Gen 3-5
Application: Toyota 3S-GE Gen 3–5 (incl. BEAMS) and 3S-GTE Gen 3–5
Part Type: Billet aluminium fuel rail
Part Number: 20-0949
The Radium 20-0949 fuel rail suits the Toyota 3S-GE and 3S-GTE Gen 3–5, including BEAMS engines. It is machined with a large 0.7in internal bore that supports the power requirements of a built engine, and both fuel rail ports are tapped for 8AN ORB so the rail can be plumbed into any fuel system with the appropriate fittings.
Three sets of billet mounting feet are supplied to suit all Gen 3–5 engines, the OEM thermal insulating spacers are reused, and no special tools are needed. On the 3S-GE Gen 3–5 and 3S-GTE Gen 4–5 the rail takes OEM top feed injectors or OEM equivalents with no modification; the side feed 3S-GTE Gen 3 needs aftermarket 48mm injectors (see Important Notes).
