1971-1972 Chevy Monte Carlo LS EFI Notched Fuel Tank Kit with 400 LPH Pump
If you're fitting an LS engine into a 1971-1972 Monte Carlo this EFI fuel tank kit solves the critical challenge of supplying reliable fuel under high horsepower conditions. It features a precision notched design that clears exhaust pipes and rear suspension components without the need for frame modifications. Equipped with an integrated fuel level sending unit and a 400 LPH pump, the module reduces heat soak and wiring clutter while maintaining consistent fuel delivery during spirited driving. Installation is simplified with tank straps, gaskets and a filler neck tailored to Monte Carlo frame rails, letting you complete the swap quickly and focus on tuning rather than troubleshooting.
Fuel Pump Design for LS Engines Producing Over 550 hp
The 400 LPH pump installed inside the tank is engineered to meet the demands of LS engines producing more than 550 hp, eliminating the risk of fuel starvation during spirited driving or track sessions. By locating the pump below the fuel level, heat soak is minimized and cavitation risk is greatly reduced, preserving consistent flow even under heavy cornering forces. This placement also keeps fuel temperature lower than an external setup, preventing vapor lock and lean conditions that can harm pistons and valves. The result is steady pressure delivery and reliable engine performance from street cruising to high rpm bursts.
Precision Notch Layout for Exhaust and Suspension Clearance
The tank's profile is CNC cut to follow the contours of the Monte Carlo frame rails and stock exhaust paths, providing full rear suspension travel without any frame alterations. This precision notch keeps the tank well clear of mufflers and coil springs, so there is no interference with chassis movement or tire clearance. Eliminating the need for trimming or bending maintains the structural integrity of both the frame and the tank. Installers can drop the new unit into place with confidence that ground clearance and component protection remain factory safe.
Integrated Level Sender for Simplified Wiring and Accuracy
Incorporating the fuel level sending unit directly into the module removes external fittings and reduces potential leak points, resulting in a cleaner installation. Fuel gauge readings become more reliable because the sender sits fully submerged, delivering true real time data across all tilt angles and fuel conditions. Wiring harnesses tuck neatly away, cutting down on clutter and making system bleeding faster during initial setup. Compatibility with most aftermarket dashboards ensures you won't need adapters or extra calibration steps.
Complete Kit Layout That Streamlines Installation
Every component required for a drop-in swap comes included: the pump module, sending unit, tank straps, filler neck, vent filter, gaskets and mounting hardware all fit the 1971-1972 Monte Carlo frame rails. With step-by-step instructions, you can remove the original tank, position the notched unit, secure straps and perform leak checks in one continuous workflow. There's no need for additional parts runs or last-minute trips to the parts store. This complete approach lets you focus on performance tuning rather than chasing missing pieces.
