1959-1960 Chevy Impala EFI Fuel Tank Kit for LS and LT Swaps
When you fit an LS or LT engine into a classic 1959 to 1960 Impala, maintaining stable fuel delivery under demanding conditions is critical. This kit combines a 400 LPH Walbro fuel pump, tank module, sending unit, vent filter and steel shell to support engines over 550 hp. Tailored to B Body frame points, it bolts in using included straps, gaskets and hardware with no trimming. Complete with tank straps, filler neck, gaskets and mounting hardware, this USA built assembly aligns with original underbody connections and conforms to precise fitment requirements. Delivering consistent fuel pressure for spirited drives and highway runs, this corrosion-resistant design ensures dependable operation in classic Impala applications.
Product Overview
The 1959 and 1960 Impala EFI Fuel Tank Kit provides a complete solution for LS and LT engine installations in 1959 and 1960 Impala, Bel Air, Biscayne and Del Ray models. This single assembly replaces the original fuel reservoir with a combined tank and high capacity pump module that installs in the factory position. By preserving the chassis rails and mounting points, the design maintains frame integrity and avoids costly custom tank fabrication. Electronic fuel injection integration is seamless, allowing modern engine management systems to operate without modification to the vehicle's structure.
Performance Capacity
At the heart of the kit is a 400 liter per hour Walbro fuel pump that ensures uninterrupted supply under demanding conditions. Its flow rate supports forced induction or naturally aspirated engines producing in excess of 550 horsepower, delivering stable pressure during rapid throttle changes and high rpm operation. The pump housing and internal components resist aeration, minimizing risk of fuel starvation under hard acceleration. This capability makes the assembly suitable for both street use and competition where steady fuel delivery is critical for engine longevity and consistent power output.
Installation and Fitment
Muscle Rods engineered the mounting solution to align perfectly with existing body mounts, ensuring proper engine placement and driveline angles are retained. The kit uses original bolt locations, avoiding welding or chassis modification. Detailed instructions cover every step from tank positioning to fuel line routing and electrical connections. Installers benefit from plug and play compatibility with factory style fittings, hose connectors and vent lines, significantly reducing labor time. The result is a fuel delivery system that integrates with minimal effort and maintains the vehicle's original underbody architecture.
Quality and Construction
Proudly made in the USA, the steel tank shell receives a corrosion resistant coating that stands up to ethanol blends and environmental exposure. All fixtures and hoses meet or exceed industry standards for pressure tolerance and leak prevention. The assembly includes OE spec sensor ports for accurate fuel level monitoring, supporting both stock gauges and aftermarket displays. Rigorous testing protocols verify that each unit performs reliably under extended duty cycles, offering the assurance that modern EFI demands are met with durable, proven design.
