As injected quantity increases, so does the drop in rail pressure during the injection event. The S\u0026amp;S Diesel Motorsport® Double-Barrel Fuel Rail offsets that drop with 2.5x the volume of a stock 6.7L Cummins rail — more pressurized fuel on demand throughout the injection event.\u003c\/p\u003e\n\u003cp\u003eReleased at the Ultimate Callout Challenge, the Double-Barrel Fuel Rail is built for max-effort 6.7L Cummins competition applications: drag racing, truck pulling, and big dyno numbers — any setup that needs large quantities of fuel injected quickly.\u003c\/p\u003e\n\u003ch2\u003eFeatures:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e2.5x (154% more) volume than a stock 6.7L Cummins fuel rail\u003c\/li\u003e\n\u003cli\u003eMaintains pressure better throughout the injection event\u003c\/li\u003e\n\u003cli\u003eMore injected quantity for the same injection duration\u003c\/li\u003e\n\u003cli\u003eImproved rail pressure control from more consistent sensor feedback\u003c\/li\u003e\n\u003cli\u003eModular design for flexible feed port, sensor, and PRV placement\u003c\/li\u003e\n\u003cli\u003eTested to 3,000 bar (43,511 psi)\u003c\/li\u003e\n\u003cli\u003eFor max-effort 6.7L Cummins competition applications (not a direct bolt-on)\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat's Included:\u003c\/h2\u003e\n\u003cp\u003eSold as a bare rail — no plugs, fittings, sensors, or pressure relief valves.
