Tailored A-Body Fitment for 1970 Monte Carlo
This fuel tank kit is engineered to match the contours of the A-Body chassis on a 1970 Monte Carlo, providing a true plug-and-play installation. By aligning precisely with factory mounting points and frame rails, it eliminates the need for trimming or fabrication. The integrated filler neck and vent filter are positioned for optimal clearance, preserving the vehicle's original undercarriage geometry. With everything designed to fit as intended, you can install the tank in minutes and maintain the car's classic stance without compromise.
Reliable Fuel Delivery with 255 LPH Walbro Pump
At the heart of the system lies a 255 LPH Walbro pump built to sustain up to 550 horsepower demands. Its submerged orientation within the tank promotes cooler operation and reduces noise, while the internal bypass valve prevents over-pressurization. This setup ensures consistent fuel flow under heavy acceleration or extended highway cruising, so engine performance remains rock solid. The result is smoother throttle response and the confidence that your LS engine will never starve for fuel in spirited driving conditions.
Complete Kit for Effortless LS Engine Swap
Rather than sourcing parts from multiple vendors, this EFI tank kit arrives with every component needed for an LS engine conversion on your Monte Carlo. Included are the in-tank pump module, sending unit calibrated for EFI gauge accuracy, tank straps, filler neck, vent filter, gaskets and mounting hardware. Each piece is selected for compatibility, so you avoid the usual runaround gathering fittings and fittings. This comprehensive package streamlines the swap and removes guesswork from your build.
Enhanced Efficiency and Engine Protection with EFI
Modern EFI technology offers more than just power gains-fuel metering adjustments adapt to load and temperature, boosting economy on daily drives while safeguarding against vapor lock on hot days. By maintaining stable pressure even during wide-open throttle, the kit prevents lean-condition spikes that can damage internal components. As a result, your LS swap enjoys both improved mileage on routine commutes and reliable performance when you push the car to its limits.
