1970-1972 Oldsmobile Cutlass A-Body LS Fuel Tank Kit
When preparing to drop an LS engine into a 1970 to 1972 Cutlass A-Body, securing a dependable fuel supply ranks at the top of any build list. The notched tank shape offers clearance for larger exhausts and tires while the 255 LPH Walbro pump maintains consistent pressure for setups up to 550 horsepower. Installation moves quickly thanks to the inclusion of the pump module inside the tank, sending unit, straps, vent filter, gaskets and hardware that fit the Cutlass structure with minimal alterations.
Notched Tank Architecture for Exhaust and Tire Clearance
The precision-cut notch in this fuel tank is more than a styling choice-it creates vital space for oversized exhaust pipes and wider tire sidewalls without grinding or trimming frame components. By integrating reinforcement around the notch opening, the tank retains structural integrity under load and road vibration. This design ensures builders can fit aggressive exhaust systems and modern performance tires without compromising ground clearance or fuel capacity.
Submerged Walbro Pump Ensuring Steady Flow up to 550 Horsepower
Housed inside the tank, the 255 LPH Walbro pump benefits from continuous fuel immersion, which aids in cooling and suppresses noise. This configuration maintains consistent pressure during hard acceleration or extended high-load conditions, effectively supporting engine setups up to 550 hp. The reduced risk of vapor lock and cavitation also promotes reliable operation on both street and track applications.
Complete EFI Conversion Package with Precision Fit
This kit delivers a fully matched assembly of sending unit, fuel pump module, straps, filler neck, vent filter, gaskets, and installation hardware. Every component is engineered to align with the 1970-1972 Cutlass A-Body fuel cavity and factory mounting points, eliminating the need to source aftermarket parts. The comprehensive nature of the package helps preserve original body contours and ensures proper sealing straight out of the box.
Streamlined DIY Installation on Classic A-Body Chassis
Installation is designed for straightforward bolt-in assembly, requiring minimal alteration to the Cutlass frame or floor pan. Detailed alignment features guide the installer to maintain factory ride height and tank positioning, while the included hardware set matches OE thread sizes and hole patterns. This approach reduces bench time for home mechanics, allowing the build to progress quickly from bare chassis to road-ready classic.
