1971-1972 Monte Carlo EFI Fuel Tank Kit - 400 LPH Pump

1971-1972 Chevy Monte Carlo EFI Fuel Tank Kit with 400 LPH Pump for LS Swap

When transplanting an LS powerplant into your 1971 and 1972 Chevrolet Monte Carlo, fuel delivery demands careful attention and this EFI fuel tank kit with a 400 LPH pump addresses the limitations of the original tank. It integrates a 400 LPH Walbro pump inside a custom fit tank that slips neatly into the A Body chassis and supports engine builds over 550 horsepower. The integrated vent filter maintains steady pressure while the precision fuel level sender keeps readings accurate under track or street driving. Installation hardware is included for a straightforward swap from your stock system so you can focus on wiring and plumbing instead of fabrication.

High Volume Fuel Delivery for LS Engine Swaps

The 400 LPH Walbro pump at the heart of this kit is engineered to supply consistent high volume fuel flow for supercharged or five hundred fifty horsepower builds. The durable in-tank pump module protects the internal mechanism from road vibration and heat soak, ensuring reliable operation under both street and track conditions. By housing the pump within the fuel tank itself, turbulence and aeration are minimized for stable supply at all throttle positions. This design also reduces pump noise and simplifies routing, allowing tuners to focus on engine calibration instead of chasing pressure drops.

Precision Fuel Level and Pressure Control

The precision fuel level sender ensures the fuel gauge offers accurate readings whether you are at wide open throttle or on a sweeping corner. The integrated vent filter maintains consistent pressure in the tank by preventing air inflow from disrupting fuel delivery. Together they deliver repeatable performance so you can rely on your instrumentation during long haul drives or demanding track sessions. This attention to calm tank behaviour translates into smooth engine operation and predictable throttle response under changing elevation or fuel load.

Custom Tank Design for 1971 and 1972 Monte Carlo

Crafted to slip seamlessly into the Monte Carlo A Body frame rails, the custom tank eliminates the need for cutting or major fabrication. Each kit includes straps, filler neck, gaskets and mounting hardware to streamline installation and reduce shop time. Detailed instructions guide enthusiasts of all skill levels through the process, from uninstalling the original tank to final plumbing and wiring. By delivering a tailored solution rather than a generic universal part, this kit retains the classic styling of your ride while unlocking modern EFI performance.
