EFI Fuel Tank Kit for 1971-1972 Chevy Monte Carlo LS Swaps
Converting your 1971-1972 Chevy Monte Carlo to LS power demands uninterrupted fuel pressure under high loads, and this EFI fuel tank kit meets that challenge with its 400 LPH pump and tailored design. By locating the pump fully submerged below fuel level, heat soak and cavitation get minimized during sustained high rpm sessions, ensuring consistency even in supercharged or over 550 hp setups. Precision notching follows the A body frame rails and exhaust route to preserve suspension travel without trimming, while the integrated sender module and all mounting hardware let installers finish without hunting for extra parts.
Submerged Pump Design for Consistent Fuel Pressure
Positioning the 400 LPH pump entirely below the fuel line ensures constant cooling from the surrounding gasoline, dramatically reducing the risk of heat soak during prolonged high-RPM operation. By maintaining the pump fully submerged, this design also minimizes cavitation, preventing vapor pockets that can interrupt flow under hard acceleration or sustained boost. The end result is a steady supply of fuel pressure even in supercharged or over 550 hp LS engine builds, eliminating the drop-off often associated with external pumps. This approach supports reliable throttle response and avoids vapor lock, so your Monte Carlo can handle spirited driving without risk of fuel starvation.
Precision Notched Geometry Preserves Suspension Travel
The tank shell features a CNC-machined notch that mirrors the 1971–1972 Monte Carlo frame rails and stock exhaust routing, freeing up room for coil springs and mufflers to clear without any chassis trimming. This precise contour maintains factory ground clearance and protects the sheetmetal from road debris, while preserving full rear suspension articulation at maximum bump travel. A perfect fit against the A-Body chassis means installers can drop the tank in place with confidence, cutting alignment and test-fit cycles to a minimum. The result is a hassle-free integration that safeguards both handling and structural integrity.
Integrated Sending Unit Simplifies Monitoring and Wiring
The in-tank level sensor is enclosed within the pump module, offering accurate real-time fuel readings across every driving angle and fuel volume. By housing the sending unit inside the sealed assembly, the design eliminates extra bulk in the trunk area and reduces potential leak points. Shorter wiring runs lead to faster gauge calibration, and the tidy installation leaves no loose components to clutter the rear panel. Technicians benefit from a streamlined bleed process and a clean look under the decklid, enhancing both safety and aesthetics.
All Inclusive Kit Streamlines Installation Process
This drop-in assembly arrives complete with tank straps, filler neck, vent filter, gaskets and all required mounting hardware, saving builders from sourcing extra parts. Detailed instructions guide you through factory tank removal, precise placement, sealing and leak-testing for a dependable result every time. With every component balanced for fit on the A-Body platform, body-shop adjustments are virtually eliminated and project timelines shrink. Delivering all essentials in one box, the kit lets you focus on tuning the LS powertrain instead of chasing missing pieces.
