LS-Compatible EFI Fuel Tank Kit with 255 LPH Pump for 1959-1960 Chevy Impala
Fitting an LS engine in a 1959 and 1960 Chevy Impala B Body demands reliable fuel delivery and the 1959 and 1960 Impala EFI Fuel Tank Kit 255 LPH Pump addresses this with an in tank module that preserves your car's factory floor pan. Precision molding against the B Body frame rails maintains stock ride height and avoids undercarriage alterations. This all in one solution ships complete with pump module sending unit straps filler neck and gaskets so installers have every part needed for a clean setup. Engineers calibrated the 255 liter per hour Walbro pump for LS demands under hard acceleration and kept electronic elements inside the tank to preserve the Impala's clean exterior appearance.
Precision Molding Protects Factory Floor Structure
The fuel tank is molded to fit the 1959 to 1960 Impala B Body rails with factory level accuracy, ensuring that the original floor pan remains unmodified. This precision mating prevents any shift in ride height that might occur when retrofitting a modern EFI system. By matching the contours of the chassis, installers avoid trimming or welding that could compromise structural integrity. The result is a robust installation that retains the classic foundation and weight distribution of the vehicle.
In Tank Pump Module Ensures Stable LS Engine Fuel Supply
Housing the 255 LPH Walbro pump inside the tank greatly reduces the chance of vapor lock by keeping fuel cooled and pressurized at the source. Engineers calibrated the module to maintain consistent flow during hard acceleration and sustained cornering, so the LS engine always sees the correct pressure. Internal electronics remain unseen, preserving the Impala's clean exterior while simplifying wiring and minimizing leak points. This hidden arrangement also positions the sending unit for precise level readings and reliable feedback to the factory gauge.
Complete Kit Design Reduces Installation Complexity
All required parts arrive together in a single package to streamline assembly and cut down on sourcing delays. The kit includes the fuel pump, in-tank module, sending unit, tank straps, filler neck, vent filter, gaskets and hardware sized to the Impala B Body frame. Tank straps mirror original dimensions to secure the assembly without altering ride characteristics or requiring shims. By limiting connections and using fit-for-purpose components, installers achieve a neat setup with fewer potential leak paths and alignment headaches.
Calibrated 255 LPH Pump Supports 550 Horsepower Output
The heart of the system is a 255 liter per hour fuel pump rated for engines up to 550 horsepower, delivering the volume modern EFI powerplants demand. Precision fluid passages maintain steady output at high rpm, which is critical for both spirited street driving and track sessions. This capacity ensures safe air fuel ratios under load, preventing lean conditions that could harm the engine. Durable internal construction resists common wear modes and delivers consistent performance over time, giving owners confidence during extended runs or spirited acceleration.
