1965-1966 Chevy Impala and Caprice B-Body LS EFI Fuel Tank Kit with 255 LPH Pump
Customizing a 1965 to 1966 Impala or Caprice B Body for an LS engine demands fuel delivery that can stand up to sudden throttle openings and sustained high load driving and this 255 LPH pump fuel tank kit addresses that need. With its heavy gauge stainless steel shell and original mounting points preserved, installation aligns directly with factory fuel lines to maintain clean underbody styling and speed up fitting. Engineers selected a 255 liter per hour Walbro module calibrated for up to 550 horsepower so pressure stays consistent during cornering and full throttle runs. By including straps gaskets a vent filter and a sending unit the kit delivers a complete EFI solution that performs reliably from the first mile.
Precision Formed Stainless Steel Shell for Corrosion Resistance
The fuel tank shell is crafted from heavy gauge stainless steel, delivering outstanding resistance to ethanol blends and road salt that often degrade classic underbodies. Precision formed panels hold their shape under pressure and temperature changes, so sealing surfaces remain uniform for a reliable leak free seal over many seasons. Stainless steel eliminates common pitting and galvanic corrosion issues, reducing the need for frequent inspections or early replacement. This material choice also maintains the factory underbody aesthetic on 1965 to 1966 Impala and Caprice frames without adding weight or compromising durability.
255 LPH Walbro Pump for Steady Fuel Delivery
At the heart of this kit is the 255 liter per hour Walbro pump calibrated to support LS engines up to 550 horsepower, ensuring consistent pressure during sudden throttle openings and hard cornering. Its internal rotor and efficient electric motor design work together to maintain ideal air fuel ratios during sustained high load driving. By preventing fuel starvation scenarios, this module sharpens throttle response and safeguards engine health under demanding conditions. The pump's flow rate is a perfect match for modern electronic fuel injection requirements without overtaxing the electrical system.
Exact Fitment for 1965 to 1966 Impala B Body Frames
Engineered specifically for Chevy's B Body platform, the tank retains all original mounting points for a true drop in experience on Impala and Caprice chassis. Inlet and outlet ports are machined to align precisely with factory fuel lines, eliminating the need for custom brackets or frame modifications. This attention to geometry preserves clean underbody styling and reduces stress on hoses and connections. Installers benefit from fewer adjustments and a smoother assembly process, allowing projects to progress without fitment setbacks.
Comprehensive EFI Conversion Kit for Fuel System Upgrades
This all inclusive kit arrives ready to install with the in tank pump module, sending unit, tank straps, filler neck, vent filter, gaskets and mounting hardware. Each component is selected for compatibility with the stainless steel shell and Walbro module to ensure reliable sealing and proper vapor venting. Having every clamp and gasket in one package removes the need to source parts from multiple vendors, speeding project timelines. The result is a streamlined conversion that delivers dependable fuel supply from the first mile of performance testing.
