LS EFI Fuel Tank Kit for 1970 Chevy Monte Carlo
Tackling the tight underbody spaces of a 1970 Chevy Monte Carlo A-Body LS swap, the 1970 Monte Carlo EFI Fuel Tank Kit with a 400 LPH pump integrates directly into the original mounting points, eliminating clearance conflicts and simplifying plumbing layouts. Housing the pump and sending unit inside a treated steel tank cuts hose connections and seals, reducing leak points and making installation more straightforward for both novice and experienced mechanics. A built in vent filter shields against moisture and debris while the calibrated 400 LPH flow supports LS engines above 550 hp without pressure drop, delivering reliable fuel supply during rapid throttle transitions.
Direct Underbody Fit for 1970 Monte Carlo A Body Chassis
Engineered specifically to match the contours and mounting points of the 1970 Chevy Monte Carlo A Body chassis, this fuel tank kit eliminates the usual clearance conflicts that plague LS swap projects. By using precision-formed straps, gaskets and mounting hardware, the assembly aligns perfectly with factory holes, minimizing fabrication work and ensuring a secure fit. Installers benefit from cleaner plumbing paths under the vehicle and fewer hose connections, greatly reducing the chance of leaks. Whether you are a first-time swapper or a seasoned pro, the straightforward alignment saves hours of mock-up time and reduces the need for custom brackets or spacers.
Built In 400 LPH Walbro Pump for 550 HP Plus Applications
The integrated Walbro pump delivers a sustained 400 liters per hour flow rate under heavy load, supporting LS engines rated above 550 horsepower without pressure drop. This calibrated performance is critical during rapid throttle shifts, ensuring injectors receive consistent fuel supply and maintaining ideal air-fuel ratios for modern engine management systems. Drivers will notice crisper throttle response and stable power delivery whether launching off the line or cruising at speed. By housing the pump internally, the design also shields it from road debris and heat soak, helping to extend the service life of the unit.
All-In-One Kit Components Cut Installation Time
Every component required for a seamless swap is included in this kit, from the fuel pump and inside-tank module to the sending unit, filler neck, vent filter, straps, gaskets and mounting hardware. Packaged with clear instructions, each piece is tailored to work together, removing the uncertainty and parts hunting that so often delay projects. The result is a single shipment that arrives ready for immediate assembly into your Monte Carlo, avoiding trips to the parts store and simplifying labor planning. Technicians can move from mock-up to final installation in fewer steps, eliminating compatibility concerns and accelerating project completion.
Treated Steel Tank for Corrosion and Impact Resistance
Constructed from robust steel and finished with a specialized corrosion-resistant treatment, this fuel tank stands up to moisture, road salts and chemical exposure far better than untreated or plastic alternatives. Its rigid shell resists dents and maintains shape under impact, protecting internal components from damage during track sessions or daily driving. Engineers subjected each unit to extreme temperature cycles and abrasion tests to confirm long-term leak-free performance. By preventing rust and scale from forming inside the tank, the system also helps keep fuel screens and injectors cleaner, reducing maintenance frequency and preserving pump efficiency.
