High-Flow LS Fuel Pump for Engine Swaps
Swapping an LS engine into a chassis designed decades earlier often exposes the factory fuel pump as a bottleneck for sustained power delivery. This kit pairs an Aeromotive 340 LPH in tank pump with CNC machined Corvette specific fittings to thread directly into the factory EFI sending unit without cutting or extra adapters. Made in USA from corrosion resistant materials, this kit installs into factory fuel lines and maintains stock routing and clearance under the chassis. With built-in flow headroom it supports future turbo or supercharger upgrades without pump replacement. The combination of precise fit and durable materials ensures reliable performance under both daily driving and spirited runs.
Compatibility and Fitment
The 1984 to 1991 Corvette LS engine mounts are engineered exclusively for installations of the LS platform in the late C4 chassis. They integrate seamlessly with MuscleRods crossmember systems to guarantee precise engine placement and correct drivetrain angles. The direct bolt-in interface attaches to original frame rails, preserving the chassis geometry and suspension pickup points. By retaining the stock mounting locations, handling dynamics remain consistent with the vehicle's design intent and potential issues related to misalignment or stress concentrations are minimized.
Construction and Durability
Manufactured in the USA from high-grade steel, each bracket undergoes a multi stage fabrication process that includes precision laser cutting, robotic welding, and a robust powder coat finish. The coating forms a protective barrier against moisture, road agents, and chemical exposure, extending service life in both daily driving and track conditions. Reinforcement ribs are strategically placed in areas subject to peak torque loads and vibration, reducing the risk of metal fatigue over time. Critical mounting holes are engineered to maintain tight tolerances, ensuring repeatable installation accuracy and consistent performance across production batches. Hardware supplied with the kit includes grade eight bolts and hardened washers, enabling installers to achieve specified torque values without concern for bolt stretch or fastener failure.
Performance and Serviceability
These mounts deliver high-performance alignment by holding the LS engine within one millimeter of the factory longitudinal centerline, optimizing driveshaft angle and reducing vibration transmitted to the drivetrain. Ample clearance around the starter and exhaust manifolds simplifies maintenance tasks such as tune ups and gasket replacements. When paired with the proper MuscleRods crossmember, installation can be completed with common hand tools in under two hours, making this solution ideal for both professional restoration shops and enthusiast garages seeking a reliable, repeatable swap platform.
This LS in tank pump offers precise fit, corrosion resistance, and ample flow headroom for sustained performance and future upgrades.
