EFI Fuel Tank Kit for 1970 Buick Skylark LS and LT Engine Swaps
The 1970 Skylark EFI Fuel Tank Kit with its precision notched shell ensures exhaust and rear tire clearance while delivering the high-flow capacity needed for LS and LT engines. Equipped with a 400 LPH pump housed in a removable module, it maintains pressure for builds up to 550 horsepower and simplifies wiring by keeping the unit submerged for cooler operation. Installers will appreciate the plug and play fitment that retains factory mounting points on the A Body chassis and includes tank straps, a sending unit, filler neck and all hardware in a single package. By combining every necessary component in one assembly, this kit cuts installation time and helps you start tuning sooner.
Notched Tank Shell Preserves A Body Structure
The laser notched shell is sculpted to match the 1970 Buick Skylark floorpan and to clear exhaust pipes and rear tire sidewalls with precise alignment. By preserving the factory strap holes the design maintains the original chassis rigidity under acceleration and cornering forces. Fitment requires no frame rail bending or extensive metal trimming, so installers can rely on a direct fit approach that honors the A Body structure. This careful adaptation merges classic styling with modern swap demands for LS and LT engines.
Submerged 400 LPH Module for Consistent Flow and Quiet Operation
The core of this system is a 400 LPH Walbro pump housed in a sealed module that remains submerged to control fuel temperature and reduce operating noise. A fine mesh sock on the inlet filters out debris before it reaches the unit, prolonging pump life and protecting fuel injectors. Under load this arrangement sustains stable pressure from idle through wide open throttle on high output LS or LT engines. The result is smooth throttle response in both street driving and track conditions.
Modular Pump Assembly Eases Maintenance Without Disassembly
Designed for quick access the pump module sits in a removable housing at the top of the tank, eliminating the need to drop the entire assembly for routine service. Technicians can replace the pump or sock filter without disturbing frame rails or fuel lines, cutting service time and minimizing spill risk. Electrical connections are confined within the module, so wiring remains organized and protected. This thoughtful layout ensures that maintenance tasks stay straightforward even in tight underbody environments.
Complete Hardware Kit Reduces Fitment Headaches
Every required part arrives in a single package to simplify the swap process. Alongside the pump module the kit includes the sending unit, strap assemblies, pre bent filler neck, vent filter, gaskets and all fasteners needed for installation. Components are pre validated to align with Skylark chassis points so fabricators can avoid sourcing match for aftermarket items. By bringing all elements together installers transition quickly from tank fitment to engine calibration without extra trips to the parts store.
This kit maintains the same precise fitment and dependable flow at moderate outputs. For the smaller capacity fuel pump Kit at 255 LPH see our 1970 Skylark 255 LPH pump Tank Kit (notched).
