LS and LT Fuel Tank Kit with 400 LPH Pump for 1957 Chevy 150/210/Bel Air/Delray
Swapping an LS or LT powerplant into a 1957 Chevy chassis demands precise fuel pressure control and the 1957 Chevy EFI Fuel Tank Kit - 400 LPH Pump delivers just that with a steel reservoir molded to factory mount points. Engineers matched a 400 LPH Walbro unit to handle more than 550 horsepower, ensuring consistent flow under hard acceleration or forced induction. Installers will appreciate a complete drop in solution that includes sending unit, vent filter, weatherproof wiring harness and all mounting hardware to eliminate clearance setbacks and custom fabrication.
Precision Molded Fuel Tank for Factory Mount Integration
The fuel tank in this kit is shaped to match the 1957 Chevy floor pan and factory bolt locations, eliminating the need for custom brackets or frame modifications. Its internal baffles maintain pump submersion during rapid acceleration and spirited cornering, preventing fuel starvation even when the tank level is low. By following the original chassis contours, installers preserve ground clearance and maintain the vehicle's structural integrity while achieving a seamless fit. This precision molding accelerates the swap process and reduces the chance of fitment issues that can delay a project.
Walbro 400 LPH Pump Supporting Over 550 Horsepower
Engineers chose a Walbro pump rated at 400 liters per hour to meet the demands of supercharged or naturally aspirated LS and LT engines producing more than 550 horsepower. Its high flow capacity ensures stable fuel delivery under sudden throttle inputs or boost spikes, keeping the air-fuel ratio within optimum limits. The pump's internal design minimizes vibration and noise, making it well suited for both street and track use. Consistent volume output under load helps prevent lean conditions that could lead to engine damage.
Modular Kit Design Streamlining LS and LT Swap Installation
This complete kit brings together the fuel pump module, sending unit, vent filter, and weatherproof wiring harness so that all critical parts install directly inside the tank. Included gaskets, straps, filler neck components, and mounting hardware are precisely matched to each other, reducing the number of separate purchases and simplifying inventory management. Clearly labeled electrical connectors guide installers through each wiring step, cutting the risk of miswiring. As a result, builders can focus on tuning and calibration instead of sourcing and fitting individual pieces.
Advanced Corrosion Resistance in Steel Tank and Hardware
All steel components in the fuel tank kit are treated with protective coatings that guard against rust and road debris exposure. Seals and gaskets are made from fuel-resistant elastomers that maintain flexibility and sealing performance over time, even under high pressure. Plated mounting straps and hardware resist environmental wear, supporting long term reliability on both daily drivers and performance builds. This attention to material selection delivers factory level durability and reduces maintenance intervals.
