LS EFI Fuel Tank Kit for 1962-1965 Chevy II/Nova X-Body
If you are swapping in a modern LS powerplant in your 1962-1965 Chevy II or Nova X-Body project this EFI fuel tank kit delivers the reliable fuel supply needed to run at peak loads. Equipped with a 400 LPH Walbro pump and in tank module design it maintains steady pressure and volume for supercharged LS setups over 550 horsepower. Installation uses factory mounting points without cutting or fabrication and includes sender, straps, gaskets and all hardware for a precise fit in your classic chassis.
Precision Tank Design for 1962-1965 X-Body Fit
This fuel tank kit leverages a direct-fit architecture that aligns precisely with factory mounting points on 1962-1965 Chevy II and Nova X-Body frames. By matching original dimensions, it eliminates the need for cutting, welding, or fabrication, preserving the structural integrity of the chassis. Enthusiasts benefit from predictable clearances around rear suspension components and exhaust routing, ensuring a seamless integration with no surprises during installation. The factory-style fit also maintains the vehicle's underbody profile, which is critical for maintaining stock ride height and avoiding contact with road debris.
In-Tank Module Ensuring Stable Fuel Pressure
Positioned inside the tank, the integrated fuel pump module keeps the Walbro unit submerged in cool fuel, reducing heat soak and preventing vapor lock under extreme load. This configuration also minimizes the distance between pump inlet and pickup, allowing consistent fuel delivery even during hard acceleration and cornering maneuvers. By maintaining a steady supply, the module safeguards against pressure spikes and drops that could lead to lean running or hesitation. The result is a reliable fuel feed that supports pulse-free operation for LS engines in demanding supercharged setups.
400 LPH Walbro Pump Supporting Supercharged LS Power
At the heart of the kit lies a 400 LPH Walbro pump capable of sustaining fuel flow for LS engines pushing beyond 550 horsepower. Walbro units are renowned for their robust motor design and precision-balanced rotors, delivering consistent output under continuous duty. This pump capacity addresses the elevated demand of forced-induction systems, ensuring that injector duty cycles remain within safe limits. With factory-tested performance data backing each unit, builders can confidently dial in fueling maps without concern for supply shortfall on track or street.
Comprehensive Components Streamlining Installation
Every element required for a complete conversion is included: sending unit, tank straps, filler neck, vent filter, gaskets, and all mounting hardware. These matched parts are engineered to work together, reducing the risk of leaks and fitment issues that often plague aftermarket retrofits. For mechanics and weekend DIYers alike, having pre-matched gaskets and properly sized straps means installation can proceed without hunting for compatible pieces. The all-in-one approach saves time, eliminates guesswork, and helps ensure a leak-free seal from day one.
