Surge Pump for Consistent Coolant Circulation in 1984-1989 Corvette Radiators
For LS and LT engine swaps in a 1984-1989 Corvette chassis, ensuring continuous coolant circulation through the factory radiator can be a challenge, and this surge pump delivers a reliable solution. This compact unit installs easily near the radiator inlet and uses a high volume electric impeller to guard against hotspots during track use or spirited driving. Moreover, the sealed housing resists corrosion and vibration, providing quiet operation even when cornering or climbing steep grades. By maintaining consistent coolant flow at varying engine speeds, it protects your LS or LT powerplant and supports peak performance in both auto and manual transmission setups.
Precision Machined Billet Aluminum Housing
The surge tank's one-piece billet aluminum construction guarantees exceptional rigidity and dimensional accuracy. By machining the housing from a solid block, the risk of seam separation or distortion under pressure is eliminated, preserving seal integrity over time. This approach also improves heat transfer away from the pumps, helping them run cooler during extended track sessions. The robust block resists fatigue from vibration and throttle-induced pulses, ensuring the assembly remains structurally sound even in high-stress environments.
Anodized Finish for Enhanced Corrosion Protection
An advanced anodized finish creates a dense oxide layer that shields the aluminum housing from moisture, road salts, and chemical contaminants. This hardened surface resists pitting and abrasion at critical mounting points and fluid ports, ensuring the unit maintains both form and function through repeated service intervals. Because the coating bonds directly to the metal, it will not peel or flake, preserving visual appeal alongside long lasting protection in the harshest underhood conditions.
Submerged Dual Pump Design Preventing Fuel Starvation
Featuring two high-volume Walbro 255 lph pumps immersed in a pressurized reservoir, this surge system keeps inlets flooded at all times to eliminate vapor lock. Under hard acceleration or lateral g-forces, the submerged configuration holds the pumps below the fuel surface, preserving steady flow and immediate throttle response. Should one pump experience a drop in output, the second unit maintains sufficient delivery to protect against lean-condition runs, safeguarding engine performance and component longevity.
Integrated AN Connections and Mounting Flexibility
Standard ‑6 AN fittings provide secure, leak proof joints that simplify plumbing to existing lines without adapters. An integrated wiring pigtail streamlines electrical hookup, reducing installation time and risk of miswiring. The modular clamp allows the surge tank to attach directly to a frame rail or nest underhood, accommodating tight engine bays without fabrication. This thoughtful design enables builders to complete the fuel system setup quickly and focus on calibration rather than hardware challenges.
