1968 Impala EFI Fuel Tank Kit with 255 LPH Pump
If you are converting a 1968 Impala to LS power, ensuring reliable fuel delivery takes priority and this EFI tank kit with a 255 LPH pump delivers the consistent pressure your build demands. Built from heavy gauge steel to match factory B body frame rails, the tank preserves ride height while resisting corrosion and dents. Inside the tank the Walbro module remains submerged under high G forces to minimize vapor lock risk and support engines up to 550 horsepower without pressure drop. Every kit arrives with a calibrated sender, vent filter and hardware to simplify installation and keep mechanics focused on assembly instead of hunting parts.
Precision Contouring for 1968 Impala B Body Frame Rails
This fuel tank is sculpted to the exact profile of the 1968 Impala B body undercarriage, matching the factory frame rails and mounting bosses without alteration. By reusing the original sender opening and strap locations, it preserves ride height and underbody clearance, so the vehicle's stance remains unchanged. Installers can simply bolt the unit into place, eliminating time spent on measurements, cutting or metal shaping. The plug and play nature of this design also protects the chassis from unnecessary stress and potential alignment errors. Overall, this precision contouring ensures that an EFI upgrade integrates seamlessly with the Impala's classic structure.
Submerged Walbro Pump Architecture for Stable Fuel Flow
At the core of the assembly, a 255 LPH Walbro fuel pump resides fully within the tank to maintain uninterrupted delivery under high demand. Keeping the pump submerged prevents vapor lock even during aggressive acceleration or spirited cornering, which is critical for engines up to 550 horsepower. Constant fuel coverage also promotes cooler operating temperatures and uniform lubrication of internal components, extending pump life. This configuration yields a steady pressure curve across the full range of engine speed, translating into crisp throttle response and reliable performance on the street or track. The in tank housing further isolates the module from exhaust heat entering the engine bay, safeguarding against pressure drop.
Robust Steel Shell Guarding Against Corrosion and Road Debris
Constructed from premium heavy gauge steel, this tank withstands impacts from gravel, potholes and everyday wear without deforming. The thick walls form a solid barrier against rust, providing years of service in humid climates or salt treated roads. Its raw steel surface can accept modern clear coats or custom paint matched to a restoration palette, preserving both function and aesthetics. The rigid structure also anchors securely to the frame, preventing vibration or slosh during hard acceleration and braking. As a result, the shell protects internal components and maintains its shape under demanding conditions.
All Inclusive Hardware Kit for Streamlined Assembly
This complete kit arrives with every component needed to finish the installation without extra trips to the parts store. In addition to the 255 LPH Walbro pump and calibrated sending unit, it includes a filler neck, vent filter, gaskets, tank straps and mounting hardware. Each item is engineered to fit the tank's geometry and the Impala's chassis, ensuring leak free connections and correct positioning. The straightforward layout and labeled parts list reduce installation complexity, making the project approachable for experienced home mechanics and professional shops alike. By delivering a single source solution, this package minimizes assembly time and eliminates compatibility questions.
