LS EFI Fuel Tank Kit with 255 LPH Pump for 1965-1966 Chevy Impala/Caprice
Whether retrofitting a vintage Impala for modern horsepower or aiming for clean underbody lines, this 1965 to 1966 Impala EFI Fuel Tank Kit with 255 LPH Pump tackles the top concern of pump starvation and pressure drop in LS conversions. This stainless steel fuel tank retains original mounting points on the B Body frame while resisting ethanol corrosion and road debris damage. It houses a 255 liter per hour Walbro pump calibrated for up to 550 horsepower so pressure stays rock solid during hard acceleration. Installers will appreciate the plug and play alignment of inlet and outlet ports, plus included straps, gaskets and a vent filter for a complete, leak free assembly.
Heavy Gauge Stainless Steel Tank Resists Corrosion
The fuel tank shell is formed from heavy gauge stainless steel, offering intrinsic resistance to ethanol blends and road salt exposure that commonly afflict classic chassis. By using precision formed panels instead of softer alloys, the tank maintains its shape under pressure and temperature variations, ensuring sealing surfaces remain uniform over years of service. This material choice eliminates the risk of pitting or galvanic attack, reducing the need for frequent inspections or repairs. Installers and restorers benefit from a maintenance free solution that preserves fit and function on 1965 and 1966 Impala and Caprice frames while safeguarding against chemical and moisture damage.
255 LPH Walbro Pump Delivers Consistent Flow for Up to 550 HP
At the core of this assembly is a 255 liter per hour Walbro module engineered to supply sufficient fuel for LS engines producing up to 550 horsepower. Its internal rotor design and efficient electric motor work in concert to maintain steady pressure under rapid throttle changes and sustained high load driving. This stability prevents fuel starvation in cornering or acceleration scenarios, preserving ideal air fuel ratios for responsive performance. The precise calibration of this pump sharpens throttle response and supports modern electronic fuel injection demands across varied driving conditions.
Precision Fitment Engineered for Classic Impala Chassis
Designed exclusively for 1965 and 1966 Impala and Caprice B Body frames, the tank retains all original mounting points to deliver a true drop in installation experience. Inlet and outlet ports are machined to line up perfectly with factory fuel lines, eliminating the need for custom brackets or frame alterations. This attention to alignment not only speeds installation but also preserves clean underbody aesthetics, reducing hose stress and potential leak paths. Professional and home garage installers alike gain confidence from a system that integrates seamlessly with the original chassis geometry.
Comprehensive Kit Components Simplify EFI Conversion
This all inclusive kit arrives ready to mount, featuring the in tank pump module, a sending unit, robust straps, a filler neck, vent filter, gaskets and all necessary hardware. Each element is selected for compatibility with the stainless steel shell and the Walbro module to ensure leak free joins and proper venting of vapor. By providing every sealing element and mounting clamp in one package, the kit removes the need to source parts from multiple vendors. The result is a streamlined conversion process that accelerates project timelines and guarantees dependable fuel delivery from day one.
