LS LT-Ready Fuel Tank with 400 LPH Pump for 1958 Impala B-Body

For effortless LS or LT swaps on your 1958 Chevy B Body, this EFI tank kit integrates a 400 LPH pump and a precision engineered module to maintain unwavering fuel pressure under over 550 horsepower loads. American built construction and seamless fitment for Impala, Bel Air, Biscayne, and Del Ray frames ensure lasting reliability, smooth fuel delivery, better economy, and straightforward integration with stock or aftermarket EFI components for confident modern driving.

1958 Chevy Impala EFI Fuel Tank Kit with 400LPH Pump for LS and LT Swaps

An LS or LT engine swap in a 1958 Chevy Impala demands reliable fuel supply and the 1958 Impala EFI Fuel Tank Kit - 400 LPH Pump delivers consistent flow to tackle those demands. It bolts to factory B body chassis points and uses original filler neck locations to preserve the classic underbody look and speed up installation. Inside the tank, a 400 LPH Walbro pump runs cool in its fuel environment while cutting noise and supports power setups up to 550 horsepower without fear of starvation under cornering or highway loads. Each sending unit gasket, vent filter and mounting hardware is preconfigured for modern EFI harnesses and regulators to keep wiring organized and block debris for accurate readings and long term reliability.

Precision B Body Alignment for 1958 Chevy Chassis

This fuel tank kit is engineered to bolt directly to the factory B Body mounting points on 1958 Chevy Impala, Bel Air, Biscayne, and Del Ray models. By matching the original filler neck and strap locations, it preserves the classic underbody appearance while eliminating the need for frame modifications. Installers benefit from reduced trial and error, as the tank hardware lines up with stock holes and brackets. This careful attention to fitment not only accelerates the swap process but also maintains proper ground clearance and fuel line routing. The result is a seamless integration that respects the vehicle's vintage design.

400 LPH Pump Module Delivering Stable Fuel for 550 HP Applications

At the heart of the assembly sits a 400 LPH Walbro pump enclosed within the tank to ensure a constant supply of fuel even under aggressive cornering or sustained highway runs. Locating the pump inside the reservoir allows the surrounding liquid to act as a heat sink, reducing operating temperature and dampening noise for quieter operation. With the capacity to support engine outputs up to 550 horsepower, this module prevents fuel starvation during rapid throttle changes or extended high load conditions. Strong component cooling and consistent flow translate into reliable throttle response and peace of mind on spirited drives.

Integrated EFI Components Streamlining Installation

Beyond the pump, the kit includes a precision sending unit, vent filter, gaskets, and all necessary mounting hardware to seal and secure the system. These parts arrive preconfigured for modern EFI harnesses and pressure regulators, which means wiring and plumbing can proceed without custom adaptations. The vent filter blocks airborne and underbody debris, protecting sensitive components and ensuring accurate fuel level readings. By supplying every gasket and strap, the kit eliminates scavenging for hard-to-find replacement parts and minimizes downtime. Installers gain a clean, organized undercarriage layout optimized for modern fuel management.

American Made Construction Ensuring Long Lasting Reliability

Manufactured under strict quality control in the United States, this fuel tank assembly employs proven materials and processes to deliver exceptional durability. Every weld, seal, and fitting undergoes rigorous inspection to meet demanding performance standards for road and track use. The corrosion-resistant tank shell and robust hardware are built to withstand fluctuating temperatures and exposure to fuel additives over years of service. With this level of craftsmanship, owners can expect consistent fuel delivery, minimal upkeep, and improved fuel efficiency that supports daily driving as well as high output LS and LT engine combinations.

To match a smaller capacity pump option consider our 1958 Impala EFI Fuel Tank Kit - 255 LPH Pump which offers a smaller capacity fuel pump Kit at 255 LPH and shares the same factory mounting points.
