1958 Chevy Impala EFI Fuel Tank Kit for LS Engine Swap
For restorers aiming to fit an LS powerplant into a classic 1958 Chevy Impala, this fuel tank kit addresses the critical need for reliable fuel delivery. It features a 255 LPH fuel pump housed inside the tank to maintain steady flow and keep engine performance consistent during spirited runs. Installation is straightforward thanks to a design that slots neatly into the stock B Body frame rails and includes all necessary fittings and straps.
Precise Fit for 1958 Chevy B Body Frames
This fuel tank kit is engineered to slot directly into the factory B Body frame rails of Bel Air, Biscayne, Del Ray, and Impala models from 1958. By matching the original mounting points, it preserves chassis alignment and avoids time-consuming modifications. The custom-formed tank shell ensures consistent clearance around suspension and exhaust components, so you maintain the classic underbody profile. Precision placement of the inlet and outlet ports further simplifies plumbing to your LS engine installation.
Integrated In Tank Fuel Pump Module
Housing the pump inside the tank shell protects it from heat soak and minimizes the risk of vapor lock during spirited driving. Submersion in the fuel supply also provides inherent cooling, which extends pump life and sustains peak performance. The module's built-in wiring connector and internal filter keep installation tidy and reduce potential leak points. This approach yields quieter operation and more consistent pressure throughout the engine's operating range.
Optimized Flow Rate for Reliable Throttle Response
Featuring a 255 LPH Walbro pump, this kit delivers sufficient volume for engines up to 550 horsepower while maintaining stable pressure under load. The steady flow rate ensures rapid fuel delivery at any RPM, which sharpens throttle response and helps your engine maintain optimal air-fuel ratios. Consistency in supply prevents lean spikes when accelerating hard or climbing steep grades. Drivers notice smoother power delivery and greater confidence on both street and track.
All Inclusive Kit for Streamlined Installation
Every necessary component is provided, from the sending unit and vent filter to durable tank straps, gaskets, filler neck, and mounting hardware. This eliminates the guesswork and sourcing delays often encountered with custom swap projects. Each piece is matched to the tank's geometry, guaranteeing proper sealing and support. With all parts in hand, you can complete the swap more quickly and return to enjoying your classic Chevy without extra trips to the parts store.
