LS EFI Fuel Tank Kit with 255 LPH Pump for 1959-1960 Chevy Impala B-Body
Swapping an LS engine into a classic Impala often hinges on reliable in tank fuel delivery and this EFI tank kit equipped with a 255 LPH pump is built to meet that need without altering the original undercarriage. It molds precisely to the B Body frame rails and arrives with the pump module, sending unit, straps and fittings required for installation. Preserving the factory floor pan and ride height while supporting engines up to 550 horsepower lets enthusiasts maintain chassis integrity and tuning confidence. Electronic components remain tucked inside the tank so the Impala's signature sheetmetal lines stay uninterrupted.
Optimized In Tank Pump Module for Consistent LS Delivery
The EFI fuel tank kit features a fully integrated in tank pump module that ensures stable fuel pressure under varying driving conditions. By housing the 255 LPH Walbro pump inside the tank, the system reduces the risk of vapor lock and maintains a steady supply of fuel at high engine speeds. Engineers calibrated the module to match the flow rate demands of LS engines, smoothing out pressure fluctuations during cornering or hard acceleration. Robust internal components resist wear and deliver reliable performance over thousands of miles. The module's compact fit within the B body frame rails also helps preserve ground clearance and allows precise placement of the sending unit for accurate fuel level readings.
Engineered Capacity Supporting Up to 550 Horsepower
At the core of this kit is a 255 liter per hour fuel pump capable of serving engines with output up to 550 horsepower without risk of fuel starvation. The pump's design incorporates precision fluid passages that maintain consistent volume at sustained high RPM operation, crucial for street or track use. This capacity allows engine tuners to push LS powerplants to the limit while preserving safe air fuel ratios. Durable construction resists common failure modes, giving drivers confidence in long runs or spirited driving sessions. Vehicle owners will find that this level of performance support removes guesswork when configuring fuel systems for modern EFI.
Streamlined Kit Components for Fast Assembly
This all in one fuel tank solution includes everything needed to complete the swap in minimal time and avoids the need for aftermarket hunting. Each package contains the pump module, sending unit, tank straps, filler neck, vent filter, gaskets and all required hardware. The straps mirror the factory style to secure the tank firmly against the frame while maintaining original ride characteristics. By reducing excess plumbing joints and components from different sources, installers can achieve a clean setup with fewer potential leak points or alignment issues. The result is a straightforward process that preserves the integrity of the factory floor pan.
Maintaining Classic Body Lines with Hidden EFI Technology
The kit preserves the signature silhouette of the 1959 and 1960 Impala by concealing all electronic elements inside the tank body. Since the pump and module remain out of sight, there is no need for external brackets or visible wiring harness trims that could alter the vintage look. Integrating the fuel sending unit within the original frame rails ensures the dashboard gauge reads accurately without requiring modifications. This design approach allows enthusiasts to enjoy smooth throttle response and modern EFI benefits while retaining the timeless appeal of the Chevrolet B body.
