No cutting or modification is required when used with compatible Radium rails. :contentReference[oaicite:10]{index=10}

Please note: This plumbing kit does not include fuel rails - it requires Radium part PN 20-0458 for complete system compatibility. The installation is straightforward, maintaining factory routing while enabling upgraded fuel delivery. Ideal for high-horsepower builds where additional fueling support is needed. :contentReference[oaicite:11]{index=11}
