The \u003cstrong data-start=\"149\" data-end=\"192\"\u003eSpool Performance Split Fuel Surge Tank\u003c\/strong\u003e was designed specifically to solve the real problems that show up when direct injection and port injection are pushed hard.\u003c\/p\u003e\n\u003cp data-start=\"318\" data-end=\"753\"\u003eAt high load, the factory high-pressure fuel pump for \u003cstrong data-start=\"372\" data-end=\"392\"\u003edirect injection\u003c\/strong\u003e creates rapid \u003cstrong data-start=\"407\" data-end=\"426\"\u003epressure pulses\u003c\/strong\u003e on the low-pressure side of the system. When DI and PI share the same fuel supply, those pulses can travel through the fuel rail and cause \u003cstrong data-start=\"566\" data-end=\"609\"\u003eunstable pressure at the port injectors\u003c\/strong\u003e, leading to inconsistent injector flow and tuning headaches. This is one of the most common causes of erratic PI behavior on high-power builds.\u003c\/p\u003e\n\u003cp data-start=\"755\" data-end=\"1112\"\u003eOur split surge tank \u003cstrong data-start=\"776\" data-end=\"827\"\u003ephysically isolates the DI and PI fuel circuits\u003c\/strong\u003e. One dedicated pump feeds the DI system, while up to \u003cstrong data-start=\"881\" data-end=\"929\"\u003ethree pumps supply the port injection system\u003c\/strong\u003e, keeping pressure smooth and consistent where it matters most. The result is \u003cstrong data-start=\"1007\" data-end=\"1087\"\u003estable PI fueling, cleaner injector control, and far more predictable tuning\u003c\/strong\u003e, even under heavy boost.\u003c\/p\u003e\n\u003cp data-start=\"1114\" data-end=\"1433\"\u003eThe separate PI circuit also allows you to \u003cstrong data-start=\"1157\" data-end=\"1211\"\u003eproperly boost-reference the port injection system\u003c\/strong\u003e, maintaining consistent injector differential pressure as boost rises. This keeps PI injector flow linear, improves safety at high load, and gives tuners precise control over fueling across the entire RPM and boost range.\u003c\/p\u003e\n\u003cp data-start=\"1435\" data-end=\"1803\"\u003eMachined from \u003cstrong data-start=\"1449\" data-end=\"1473\"\u003ebillet 6061 aluminum\u003c\/strong\u003e, the surge tank is built for durability and long-term reliability in high-ethanol and high-horsepower environments.
