Spool Performance Split Fuel Surge Tank
High-horsepower engines demand more than just increased fuel volume—they require stable, predictable fueling across all conditions. The Spool Performance Split Fuel Surge Tank addresses one of the most common challenges in high-power builds: pressure instability between direct injection (DI) and port injection (PI) systems.
At high load, the factory high-pressure fuel pump generates rapid pressure pulses on the low-pressure side. When DI and PI share the same supply, these pulses can travel through the fuel rail, causing inconsistent PI injector flow and tuning difficulties. The split surge tank solves this by physically isolating the DI and PI circuits, ensuring smooth, consistent pressure where it matters most.
