LS Swap EFI Fuel Tank Kit with 255 LPH Pump for 1971-1972 Chevy Monte Carlo
When fitting an LS powerplant into a 1971 or 1972 Chevy Monte Carlo, proper fuel delivery hinges on a tank designed to clear the A Body rails and house a reliable pump. Its notched steel construction aligns with exhaust routing and secures the unit without extra brackets. The included 255 LPH pump delivers consistent flow under heavy throttle and supports outputs up to 550 horsepower. Service tasks stay fast and simple thanks to direct access through the notch, letting technicians remove the module without dropping the entire tank.
Tailored Tank Geometry for Monte Carlo A Body Rails
The fuel tank's notched profile contours precisely to the 1971-1972 Monte Carlo A Body frame rails, ensuring a seamless fit without trial and error. By accommodating the factory exhaust routing, it prevents heat buildup and interference with suspension or tire assemblies. This engineered shape also holds the fuel lines in the correct position, securing the entire unit evenly without the need for extra brackets. Installers benefit from reduced test fitting and trimming, making the swap process more efficient.
Consistent Fuel Delivery with 255 LPH Walbro Pump
At the core of this kit is a 255 LPH Walbro pump designed to meet the demands of an LS engine producing up to 550 hp. Its internal design maintains steady flow during hard acceleration and sustained cornering, preventing fuel starvation and safeguarding engine performance. Locating the pump inside the tank also dampens operational noise and lowers the risk of vapor lock in hot conditions. By matching pump capacity to LS requirements, the system delivers reliable fuel rail pressure essential for precise engine tuning.
Rapid Pump Service Through Integrated Notch
The distinctive notch in the tank top grants direct access to the pump module, so technicians can reach the assembly without dropping the entire tank. A simple removal of the retaining ring allows the module to be lifted out in minutes for inspection, maintenance or upgrades. This shortcut cuts labor hours significantly and eliminates the extra steps of lowering and reinstalling the tank. Quick access also helps prevent heat-related wear by speeding up routine service intervals.
All Inclusive Fuel System Components
This kit brings together every component needed for a turnkey installation: pump module, sending unit, filler neck, vent filter, gaskets, straps and mounting hardware. Each piece is selected to work in harmony, eliminating compatibility issues that often occur when sourcing parts separately. The sending unit fits standard gauge connections straight out of the box, so there’s no adapter splicing. With all parts on hand, installers can complete the fuel system build without last-minute visits to the parts store.
