1971-1972 Chevy Monte Carlo LS EFI Notched Fuel Tank Kit with 255 LPH Pump
Fitting an LS engine into a 1971 to 1972 Chevrolet Monte Carlo requires fuel delivery you can trust under every driving demand and this notched tank kit addresses that challenge head on. A precisely formed steel reservoir follows the Monte Carlo A Body frame rails to maintain clearance for factory exhaust and suspension components while locating fuel lines correctly behind the rails. Designed with an access notch, the integrated 255 LPH pump lifts out without lowering the tank so maintenance checks take minutes rather than hours. Whether you are tuning for street or strip this solution supports up to 550 horsepower with steady rail pressure and a straightforward installation.
Precision Shaped Steel Reservoir for A Body Frame Compatibility
The tank shell is formed from laser cut steel plates pressed to match the contours of the 1971-1972 Monte Carlo A Body frame rails, achieving a seamless integration without the need for custom brackets or spacers. Its carefully drafted profile maintains safe clearance for factory exhaust paths and rear suspension linkages, preventing heat soak or rubbing under load. By distributing the fluid weight evenly below the chassis, this reservoir supports stable handling and consistent ride height regardless of fuel level. The robust steel construction resists deformation from road debris or impacts, ensuring the tank retains its exact shape over years of service. Attention to dimensional accuracy also simplifies alignment of fuel lines and mounting straps, allowing installers to proceed with confidence from the first test fit through final installation.
255 LPH Walbro Pump Delivering Steady Fuel Flow at Power Demands
Integrated within the reservoir is a Walbro 255 LPH pump capable of sustaining pressures required for LS engines up to 550 horsepower. Submerged operation keeps the pump motor immersed in fuel where it draws cooling and lubrication, reducing heat related wear and minimizing the risk of vapor lock under aggressive cornering or extended high load. Its consistent volumetric output preserves injector balance, which translates into smoother throttle response when accelerating out of turns or during rapid throttle modulation. The pump's internal check valves maintain rail pressure at engine shut-off, preventing fuel rail collapse and ensuring immediate startup without fuel starve. In addition, the proven design of this unit offers quiet performance and long runtime under demanding conditions, making it a reliable cornerstone for both street driving and occasional track use.
Notch Access Design for Effortless Pump Service
The unique cutaway section along the tank's top surface provides direct entry to the pump assembly, removing the need to lower the entire reservoir for routine maintenance. Once the locking ring is released, technicians simply lift out the module and filter screen in a matter of minutes, allowing swift inspection of the inlet strainer or replacement of worn components. This feature saves valuable shop time, particularly in motorsport settings where quick turnaround between sessions is critical. By addressing debris buildup or strainer wear early, the system helps avoid unforeseen fuel flow restrictions and potential engine lean-out. Furthermore, simplified access supports periodic sending unit checks without disturbing surrounding fuel lines or suspension parts.
Comprehensive Component Set for Streamlined Installation
This ready to install kit arrives complete with all necessary hardware: tank straps matched to body mounting points, a precision-formed filler neck, vent filter, sending unit calibrated to stock gauge connectors, gaskets and mounting bolts. The inclusion of a preassembled pump module and sending unit eliminates guesswork in wiring and plumbing, while the vent filter enhances tank breather reliability under variable pressure cycles. Each component adheres to factory tolerances, ensuring leak free seals and correct alignment from the first trial fit. By reducing the need for aftermarket adapters or modifications, the kit condenses parts sourcing and fitment into a single cohesive package. Whether tackling a weekend swap or preparing a competition build, this comprehensive solution allows installers to complete the fuel system in significantly less time with built-in confidence in long term durability.
