1953-1954 Chevy Stock Capacity EFI Fuel Tank Kit with 400 LPH Pump
If you are planning an LS or LT engine swap in a 1953 or 1954 Chevy this EFI fuel tank kit makes it simple to maintain the factory 18 gallon capacity while meeting the demands of modern injectors. With a reliable 400 LPH Walbro pump mounted inside the tank you get consistent fuel flow for powerplants over 550 horsepower without heat soak or cavitation issues. All mounting hardware and a direct fit design align with factory frame points so installation stays straightforward and frees you to focus on EFI calibration rather than chassis modification.
Integrated 400 LPH Pump for Consistent Fuel Flow
This kit's internally mounted 400 LPH Walbro pump maintains stable pressure even under peak demand, supporting engines above 550 horsepower without interruption. By situating the pump inside the tank, heat soak is minimized and cavitation is prevented, so fuel stays cooler and vapour lock is avoided. The result is a steady high volume supply that translates into sharper throttle response across the entire RPM range. This design ensures you can push your classic Chevy harder with confidence in its fuel delivery system.
Corrosion-Resistant Steel Tank Preserving Stock Capacity
The replacement tank is formed from heavy gauge steel and finished with a robust powder coated surface to fend off rust and road debris. This corrosion-resistant construction retains the original 18-gallon capacity, providing the full driving range enthusiasts expect from a period-correct build. Its durable shell resists impact and chemical exposure, so it maintains structural integrity and appearance over many seasons. By blending modern materials with a classic profile, it offers both authenticity and reliability.
Direct Fit Assembly Simplifying Classic Chevy Upgrades
Every component is engineered for seamless alignment with the 1953–1954 Chevy frame, eliminating the need for chassis modifications or custom mounting brackets. The kit includes the pump module, sending unit, heavy-duty straps, filler neck, vent filter, gaskets, and all necessary hardware, along with clear, step-by-step instructions. Installers benefit from factory-style mounting points that guarantee precise positioning and easy access for future service. This plug-and-play approach lets builders focus on EFI tuning rather than fabrication.
