1971-1972 Chevy Monte Carlo LS EFI Fuel Tank Kit with 255 LPH Pump
If you're retrofitting an LS powerplant into a 1971 to 1972 Monte Carlo on the A body chassis this EFI fuel tank kit with its integrated 255 LPH pump solves alignment and clearance challenges by matching the original frame bracket locations. Designed to house the Walbro pump inside a steel cell the assembly keeps operating temperatures low and muffles vibration for quieter operation. It also supports up to 550 horsepower for both naturally aspirated and forced induction setups. Installers benefit from all required straps gaskets and hardware in one package to achieve consistent fuel delivery without modifying factory routing.
Optimized Pump Placement for Efficient Cooling and Quiet Operation
This EFI tank design houses the 255 LPH Walbro pump directly inside a steel fuel cell, allowing the pump to run immersed in a constant bath of fresh fuel. By keeping fuel temperatures lower, the assembly reduces thermal stress on internal pump components and helps maintain consistent output even under sustained high load. The surrounding steel walls act as a sound barrier, damping vibration and mechanical noise before it reaches the chassis and passenger compartment. As a result, drivers experience a smoother and quieter ride without sacrificing the ability to support up to 550 hp in both naturally aspirated and forced induction setups.
Exact Fitment on 1971 to 1972 Monte Carlo A Body Chassis
Precision-engineered bracket and vent fitting points match the original frame locations on the A Body platform, eliminating the need for custom bracket fabrication or chassis modifications. This tailored approach preserves the structural integrity of the factory frame rails and ensures a leak-free installation that resists seal fatigue over time. Installers spend less effort on trial and error since the tank drops into place with proper clearance at all key mounting and fuel line interfaces. The precise fitment preserves original fuel routing and underbody geometry, maintaining critical ground clearance and preventing interference with suspension components.
Comprehensive Kit Contents Streamline the Installation Process
All required parts are supplied in one package, including the in-tank pump module, sending unit, tank straps, filler neck, vent filter, gaskets and mounting hardware. Prefit gaskets and precision-sized straps remove guesswork and help achieve leak-free connections the first time around. The integrated filler neck snaps into the original opening without modification, while the vent filter ensures proper evacuation of vapors under every operating condition. By delivering a single-source solution, this kit cuts installation time dramatically and reduces the risk of missing adapters or hardware when converting to LS EFI.
Consistent Fuel Delivery Supporting Up to 550 Horsepower
The carefully selected 255 LPH flow rate provides a margin of safety for engines producing up to 550 hp, ensuring stable pressure at peak demand. Positioning the pump in the cell's lowest point prevents vapor lock, so throttle response remains crisp even during rapid acceleration or long cornering stints. Drawing fuel directly from the steel cell allows the pump housing to act as its own vibration and noise damper, smoothing out pressure spikes that can shorten service life. This reliable delivery under wide open throttle conditions preserves engine performance and minimizes the risk of lean‐condition damage on both street and track applications.
