1965-1966 Chevy Impala and Caprice LS EFI Fuel Tank Kit with 255 LPH Pump
Adapting an LS engine to a 1965 or 1966 Impala or Caprice chassis requires reliable fuel delivery under all conditions, and this 1965 to 1966 Impala EFI Fuel Tank Kit with 255 LPH Pump tackles that challenge with precision. The stainless steel shell resists corrosion from ethanol blends and road salts while preserving factory mounting points on the B Body frame for a true drop in fit. Complete with straps, gaskets and a vent filter, it houses a 255 liters per hour Walbro module to support builds up to 550 horsepower without pressure loss. Installers will appreciate ready to mount simplicity and consistent performance during hard acceleration or extended highway runs.
Stainless Steel Construction for Lasting Corrosion Resistance
The fuel tank shell is crafted from heavy gauge stainless steel to withstand chemical attack and moisture over time. Its material composition resists ethanol blended fuels and road salts without pitting or weakening, preserving tight manufacturing tolerances even under temperature changes. By avoiding softer metals, the tank maintains its shape and sealing surfaces, reducing the risk of leaks and deformation. Technicians benefit from a maintenance free component that remains structurally sound through years of service. This durability ensures classic Impala and Caprice restorations retain reliable fuel containment without frequent repairs.
Optimized 255 LPH Walbro Pump Ensuring Stable Flow
At the heart of this kit is a 255 liter per hour Walbro module calibrated to support LS swaps delivering up to 550 horsepower. The pump's precision internal design controls pressure swings, preventing fuel starvation during hard acceleration or sustained cornering. Consistent volume delivery sharpens throttle response and helps maintain air fuel ratios under all driving conditions. Whether cruising on the highway or pushing performance, drivers experience a constant feed that minimizes lean runs. This level of control is critical for modern EFI systems feeding high output engines.
Precision Fitment on B Body Chassis for Seamless Integration
Designed specifically for 1965 and 1966 Impala and Caprice B body frames, the kit retains all factory mounting points for a true drop in installation. Inlet and outlet ports are machined to match original fuel lines, eliminating the need for cutting or welding on the frame. This exact alignment safeguards against misrouting and stress on hoses, leading to a clean underbody layout. Installers save time by avoiding fitment trials and custom brackets. The result is a watertight installation that respects the classic chassis without alteration.
Comprehensive Kit Design Simplifies EFI Conversion
This all inclusive assembly comes with a complete set of straps, gaskets, a vent filter, plumbed filler neck and sending unit ready for mounting. Each component is selected for compatibility with the stainless steel tank and the Walbro pump module, guaranteeing leak free joins and proper venting. By providing hardware and sealing elements in one package, the kit removes the need to source parts from multiple suppliers. Home garage installers and professional shops alike gain confidence in a cohesive system engineered to work out of the box. The streamlined process accelerates the conversion timeline and ensures dependable fuel delivery from day one.
