1981-1988 Oldsmobile Cutlass G-Body LS Fuel Tank Kit with 255 LPH Pump
If you're swapping an LS into a 1981 to 1988 Cutlass G-Body and need a reliable fuel supply under increasing demand, the 1981-1988 Olds Cutlass EFI Fuel Tank Kit featuring a 255 LPH pump delivers consistent flow and pressure for up to 550 horsepower. Built to line up with factory flange and strap positions, it installs without cutting or welding and retains the original ride height and chassis integrity. Featuring corrosion resistant steel construction and a precision machined module, the assembly keeps internal turbulence to a minimum. Technicians benefit from a complete package that includes the sending unit, filler neck, vent filter, gaskets, and mounting hardware for a truly bolt in solution.
Factory Aligned Fit for 1981 to 1988 Cutlass G Body
The fuel tank's flange and strap layout is engineered to fit original mounting points on Cutlass G Body models from 1981 through 1988. By matching factory height and alignment, the kit installs without cutting or welding and preserves chassis geometry. This precision reduces stress on weld seams and keeps the tank sealed against road debris. Installers benefit from a seamless transition to modern EFI performance while retaining ride height and handling characteristics.
Combined Pump and Sender Module Reduces Turbulence
The in tank module merges a 255 LPH Walbro pump and a precision sending unit into a single assembly that minimizes internal fittings. This design cuts down on leak paths and maintains constant flow under rapid throttle changes or high RPM. Calibration to support up to 550 hp ensures fuel pressure remains stable during sustained demand. Tuners and drivers gain more accurate maps and consistent engine response thanks to reduced internal turbulence.
Corrosion Resistant Steel Shell and Hardware
Every major structural component is crafted from high grade steel selected for its resistance to corrosion, wear, and vibration fatigue. The shell, straps, and mounting hardware receive protective treatments that withstand moisture, road salt, and extreme temperature swings without rusting. Seals and gaskets are tailored to the metal surfaces to prevent leaks over many seasons of use. Whether on daily errands or track laps, the tank endures demanding conditions reliably.
Comprehensive Kit Unifies All Installation Essentials
Delivering the pump module, sending unit, filler neck, vent filter, gaskets, straps, and mounting hardware in one package, this kit saves time and eliminates compatibility checks. Each component is engineered to interface seamlessly, guiding installers through a straightforward bolt in procedure. By consolidating items, technicians avoid additional trips for missing parts. The result is efficient assembly and immediate readiness for engine tuning and road testing.
This tank kit maintains consistent fuel pressure under sustained demand and installs with ease. To upgrade to a larger capacity fuel pump Kit at 400 LPH see our 1981-1988 Olds Cutlass 400 LPH Pump Tank Kit.
