EFI Fuel Tank Kit with 400 LPH Pump for LS Swap 1970 Chevy Monte Carlo
When swapping an LS into a 1970 Chevy Monte Carlo A-Body chassis reading up on fuel delivery solutions quickly reveals this EFI Fuel Tank Kit with 400 LPH pump addresses tight clearance and plumbing challenges by integrating the pump and sending unit into a treated steel tank. Contoured straps and precision gaskets align with factory mounting points saving hours of modification work. With an integrated vent filter and a calibrated 400 LPH pump capable of handling over 550 horsepower applications the design protects against moisture and debris while maintaining consistent flow during rapid throttle transitions.
Factory-Style Underbody Fit for 1970 Monte Carlo A Body
This EFI fuel tank kit is engineered to match the exact contours and factory mounting points of the 1970 Chevy Monte Carlo A Body chassis, eliminating the common clearance conflicts in LS swap projects. Precision-formed steel straps and molded gaskets secure the tank without altering the original mounting holes, saving hours of trial and error on custom brackets. Aligning the fuel sender and pump module directly with the body rails simplifies plumbing lines under the car and reduces the number of hose connections required. Whether you are tackling your first engine conversion or refining a proven build, this fitment strategy minimizes fabrication work and streamlines the path from mock up to final installation.
400 LPH Walbro Pump Supporting 550+ Horsepower Applications
At the heart of this kit is a 400 liters per hour Walbro pump calibrated to maintain consistent pressure in engines producing more than 550 horsepower. This capacity is crucial during rapid throttle transitions and high load conditions, ensuring injectors receive an uninterrupted flow of fuel to preserve optimal air-fuel ratios. By housing the pump module inside the tank, the design isolates it from road debris and reduces heat soak that can impair performance. The internal placement also lowers noise levels and helps the pump draw cooler fuel, extending its service life and delivering reliable operation in supercharged or naturally aspirated powerplants.
Corrosion-Resistant Treated Steel Tank Durability
Constructed from robust steel and finished with a specialized corrosion-resistant treatment, this fuel tank stands up to moisture, chemical exposure and road salt far better than untreated alternatives. Its rigid shell resists dents and preserves shape under impact, protecting the internal pump and sender from damage during spirited driving or track use. Engineers validated the coating through extreme temperature cycles and abrasion tests to guarantee leak-free service over many seasons. By preventing rust and scale formation inside the tank, the system also helps maintain clean fuel screens and injector tips, reducing maintenance intervals and safeguarding pump efficiency.
Comprehensive Kit Design Streamlining Fuel System Assembly
Every element required for a seamless LS engine swap into a Monte Carlo A Body chassis arrives in one complete package, from the pump and inside-tank module to the sending unit, filler neck, vent filter, straps, gaskets and mounting hardware. Each component is selected and configured to work together, eliminating the need for parts hunting or last-minute trips to the store. Clear step-by-step instructions guide both first-time installers and seasoned technicians through the process, reducing labor time and avoiding compatibility concerns. The streamlined layout accelerates project timelines by allowing builders to move directly from initial setup to final plumbing with confidence in fit and function.
