Electric Water Pump Inline Black

The ALLSTAR PERFORMANCE Electric Water Pump Inline Black (ALL31130) is a self-contained electric cooling solution engineered for high-performance engine builds where traditional belt-driven pumps create parasitic losses or installation constraints. This aluminum inline pump delivers consistent flow independent of engine RPM, making it ideal for custom hot rods, street machines, and race applications where cooling reliability and space efficiency are critical considerations.

The pump features 1-1/4-inch NPT O-ring inlets and outlets, allowing straightforward integration into custom cooling systems with industry-standard hose fittings. Black anodized aluminum construction provides corrosion resistance while keeping weight minimal—a 6.2 lb package that won't burden fuel economy or handling balance. The inline configuration positions the motor perpendicular to flow direction, enabling compact mounting in engine bays where traditional centrifugal pumps would interfere with accessories or headers. Electric operation means cooling output responds precisely to engine load rather than engine speed, reducing coolant temperature variation and improving thermal efficiency across the entire RPM range.

This pump suits builders integrating modern cooling upgrades into vintage platforms, LS engine swaps, or late-model restorations where OEM water pump mounting bosses don't align with the new powerplant. The all-in-one kit design includes everything needed for installation, eliminating compatibility guesswork. Electric water pumps in this class are standard in contemporary road racing, where consistent operating temperatures directly impact engine longevity and predictable performance under sustained high load.

ALLSTAR PERFORMANCE's positioning in the performance cooling market reflects decades of track-focused engineering. The inline configuration and anodized finish have proven themselves across thousands of competition builds, where cooling system failures are measured in lost race results and repair downtime rather than inconvenience.
