1971-1972 Chevy Monte Carlo Notched Fuel Tank Kit for LS Swap
This 1971-1972 Monte Carlo EFI Fuel Tank Kit featuring a 400 LPH pump addresses the critical issue of consistent fuel delivery in LS engine conversions. By positioning the pump fully below the fuel level the assembly reduces heat soak and limits cavitation during spirited driving and sustained loads. Its precision cut notch follows the Chevy frame rails and stock exhaust route to preserve full rear suspension movement without any trimming. Installation comes complete with tank straps gaskets a filler neck and mounting hardware for a streamlined fit on A Body chassis.
Submerged 400 LPH Pump Ensuring Steady Flow for Over 550 hp LS Engines
This EFI tank kit features a fully submerged 400 LPH pump that sustains consistent fuel flow even under extreme load. Housing the pump below the fuel level significantly reduces heat soak and prevents cavitation during rapid throttle changes or extended track driving. With constant cooling from surrounding fuel, the assembly avoids vapor lock and noise issues inherent to external units. The result is a reliable supply pressure that keeps supercharged and high output LS engines running without fuel starvation at peak RPM.
CNC Cut Notch for Exhaust Path and Suspension Clearance
A precision CNC cut notch follows the 1971–1972 Monte Carlo frame rails and stock exhaust routing to maintain full rear suspension articulation. This contour allows coil springs and mufflers to clear the tank under heavy compression without any trimming or chassis modifications. By preserving factory ground clearance, the design protects the tank from road debris while retaining original handling characteristics. Installers benefit from a drop in fit that aligns perfectly on the A-Body chassis, cutting alignment trial runs to a minimum.
Integrated Fuel Level Sender for Accurate Monitoring and Cleaner Install
The in-tank sending unit provides precise real time data across every driving angle and fuel condition. Mounting the level sensor inside the sealed module eliminates extra leak points and shortens wiring runs in the trunk area. This tidy setup reduces gauge calibration time and ensures compatibility with standard aftermarket dashboards. Less clutter and fewer connections mean faster bleeding procedures and a more professional appearance under the rear panel.
Comprehensive Kit with Corrosion-Resistant Build for Streamlined Setup
This complete fuel tank package includes tank straps, gaskets, a chassis-specific filler neck, vent filter and all required mounting hardware to simplify a drop-in swap. Components are crafted from premium materials and treated to resist chemical attack and corrosion under prolonged exposure. Detailed instructions walk through factory tank removal, sealing, and leak testing to ensure a dependable installation. By delivering every part in one box, the kit eliminates multiple parts runs and lets builders focus on tuning rather than sourcing missing pieces.
