Surge Tank QSST Dual 340 LPH Pumps

The Surge Tank QSST Dual 340 LPH Pumps from FUELAB FUEL SYSTEMS is a professional-grade surge tank assembly designed for high-performance fuel delivery in modified vehicles that require redundant pump capacity. This product is ideal for serious automotive enthusiasts and mechanics working on turbocharged, supercharged, or naturally aspirated performance builds, addressing fuel delivery challenges that arise when stock systems cannot support power levels exceeding 400–500 hp.

The dual-pump architecture allows for a combined flow rate of 680 LPH at full load, with each pump operating independently to mitigate cavitation and fuel starvation during demanding driving conditions. The QSST design is engineered to manage transient demand spikes, which is crucial during acceleration when fuel rail pressure can fluctuate. This surge tank is compact, measuring 12.6 × 12.3 × 16.1 inches, making it suitable for various engine bay or trunk-mounted fuel system configurations.

With a weight of 10.65 lbs, the Surge Tank QSST balances structural integrity with weight efficiency, a key consideration for performance vehicles where minimizing rotational and unsprung mass is essential. This product is particularly beneficial for those tuning street cars for reliability or building track-focused platforms, ensuring consistent fuel delivery under various driving conditions.
