1971-1972 Chevy Monte Carlo LS EFI Fuel Tank Kit with 255 LPH Pump
When installing an LS EFI system into a 1971-1972 Chevy Monte Carlo, proper fuel supply hinges on a tank crafted to clear the A Body rails and mount a reliable pump. Engineered with a notched steel profile, this unit matches factory exhaust paths and secures without extra brackets while positioning fuel lines correctly. A Walbro 255 LPH pump inside the tank maintains steady high flow during aggressive throttle events and supports up to 550 hp for consistent performance. By granting direct access through the notch, routine service tasks become faster since the pump module can be removed without lowering the entire tank.
Precision Matched Tank Profile for A Body Frame Rails
The fuel tank is sculpted to the exact contours of the 1971-1972 Chevy Monte Carlo A Body rails, eliminating fitment guesswork and extensive trial adjustments. Its sculpted sides align with factory exhaust routing, maintaining proper clearance to prevent heat soak and interference with suspension or tire assemblies. This tailored profile also secures fuel lines in the correct position behind the frame rails, ensuring consistent attachment points without the need for additional brackets. Installers save time by avoiding trimming or test fitting, while final assembly benefits from even load distribution across the vehicle's underbody. The result is a seamless integration that upholds chassis integrity and supports reliable operation under all driving conditions.
Engineered 255 LPH Pump Performance Matching LS Demand
Central to the kit is a 255 LPH Walbro pump engineered to satisfy the fuel requirements of an LS engine producing up to 550 horsepower. Its internal design maintains a steady fuel supply during rapid throttle openings and sustained cornering, virtually eliminating lean conditions that can compromise engine tuning and power output. Placed inside the tank, the pump benefits from constant fuel cooling and reduced noise transmission, while also lowering the risk of vapor lock in high underbody temperatures. By precisely matching pump capacity to the LS EFI system, the assembly delivers consistent rail pressure, supporting tighter injector control and optimizing combustion efficiency at all engine speeds.
Access-Optimized Notch for Rapid Pump Servicing
The integrated notch in the tank's upper surface grants immediate access to the pump module, allowing technicians to perform inspections and replacements without removing the entire assembly. Removing a single retaining ring releases the module for lift-out in minutes, cutting labor time and lowering service costs. This design also speeds routine preventative maintenance, reducing downtime between performance checks. With fast access to the sending unit and filter screen, any debris or wear indicators can be addressed on the spot, helping to maintain consistent fuel flow and protecting the engine from potential damage caused by clogged or weakened components.
Complete Fuel System Kit for Streamlined Installation
This all-inclusive fuel system bundle assembles every component required for a turnkey conversion: tank straps, filler neck, vent filter, sending unit, gaskets and mounting hardware. Each part is chosen to integrate seamlessly, preventing leaks and eliminating compatibility conflicts that often arise when sourcing items separately. The sending unit and pump module arrive calibrated to standard gauge connections, so installation teams can complete wiring and plumbing without adapters or splicing. By having every critical piece on hand, technicians avoid last-minute parts runs and ensure a consistent, leak-free assembly from the outset, streamlining the transition to LS power.
