EFI Fuel Tank Kit for 1959-1960 Chevy Impala LS and LT Swaps
When you fit an LS or LT engine into a classic Impala B Body this 1959-1960 Impala EFI Fuel Tank Kit with a 400 LPH pump addresses the need for rock steady fuel pressure during spirited driving and long freeway stretches. It combines a 400 LPH Walbro pump, sending unit and vent filter in a single corrosion resistant steel module that bolts to factory frame points without trimming. Installers benefit from precision matched fittings and straps that align with original underbody locations preserving the car's historic lines while supporting engines over 550 hp with reliable flow.
Optimized 400 LPH Walbro Pump for LS LT Engines
The heart of this tank kit is a Walbro fuel pump that moves 400 liters each hour to keep pressure stable even when output exceeds 550 hp. Positioned inside the fuel reservoir, it uses surrounding fuel as a coolant to prevent vapor lock and lower operating temperatures. This steady flow rate supports supercharged setups and sudden throttle inputs without pressure dips, preserving precise mixture and smooth acceleration. By maintaining consistent supply under stress, the kit safeguards engine timing and response during long highway drives or spirited runs.
All in One Pump Sending Unit and Vent Filter Module
This design integrates the pump, sending device and vent filter into a single in tank unit that aligns with factory fittings. Technicians bypass extra hoses and connections by following preset terminations that guide correct routing. Fewer joints reduce leak paths and wiring errors while speeding up installation time. The streamlined approach delivers greater system reliability and cuts shop labor when upgrading classic Chevrolet B body cars.
Exact Fitment for 1959 1960 Chevy Impala Underbody
Every strap, bracket, gasket and mounting bolt is tailored to the original frame points of 1959 and 1960 Impala models including Bel Air, Biscayne and Del Ray editions. This precision match means no trimming or drilling of the chassis and preserves the vehicle's geometry and original profile. Robust steel straps clamp the tank firmly to withstand cornering loads and road shocks. Restorers maintain the classic appearance while gaining modern fuel delivery capability.
Corrosion Resistant Steel and US Built Hardware
The kit employs stainless grade steel and advanced gasket materials engineered for exposure to ethanol blends and harsh environments. Strict quality control at US facilities ensures each component arrives free from flaws that could lead to leaks or rust. Hardened bolts and precision hardware secure the assembly to resist loosening under vibration or heavy use. Drivers gain confidence knowing the fuel system will endure coastal climates and winter road treatments alike.
