LS Fuel Tank Kit for 1981-1988 Oldsmobile Cutlass G-Body
Owners tackling an LS swap in an Oldsmobile Cutlass from 1981 to 1988 know that fuel starvation can ruin performance when power climbs beyond the factory fuel system; this EFI Fuel Tank Kit pairs a 255 LPH Walbro pump with a precision machined module to restore flow up to 550 horsepower. Installation is bolt-in and follows the factory flange and strap locations so the tank seats exactly as the original without cutting or welding. Every necessary component from the filler neck and vent filter to gaskets is included to streamline the setup. As a result each injector receives the consistent pressure required for accurate tuning under both street and track conditions.
Precision Engineering for 1981 to 1988 Cutlass G Body
The fuel tank kit is crafted to the exact flange and strap dimensions of 1981 to 1988 Oldsmobile Cutlass G Body models, ensuring a perfect match without modification. By aligning with factory mounting points, the assembly preserves the integrity of the chassis and avoids any stress that could arise from misaligned hardware. This attention to fitment means installers can rely on a secure seal against road debris and moisture, reducing the chance of leaks or premature wear. As a result, the tank sits exactly where the original did, maintaining the vehicle's ride height and handling characteristics.
Integrated 255 LPH Walbro Pump Module for Stable Flow
The in-tank module combines a 255 LPH Walbro pump with a precision sending unit to deliver consistent fuel pressure even under high demand. Calibrated to support up to 550 horsepower, this unit minimizes internal turbulence and prevents pressure drops during rapid throttle openings or sustained high rpm. Housing both pump and sender in one assembly also cuts down on internal fittings and potential leak points, making maintenance simpler. Drivers and tuners benefit from uniform delivery, which is essential for accurate fuel mapping and sharp throttle response on both street and track.
Durable Steel Construction for Street and Track
Every major component of the tank system is formed from high grade steel chosen for its resistance to corrosion, wear, and vibration fatigue. The shell, straps, and hardware are treated to withstand moisture, road salt, and temperature changes without rusting or cracking. High quality gaskets and seals are matched to the metal parts to maintain a leak free joint over years of use. Whether you drive daily or push the car hard at the track, this robust construction ensures the fuel tank remains a reliable foundation for the entire fuel delivery system.
All In One Kit Streamlines Installation Workflow
This comprehensive kit unites the pump module, sending unit, filler neck, vent filter, tank straps, gaskets, and mounting hardware in one package. Builders no longer need to source separate parts or verify compatibility across multiple vendors, saving valuable shop time. The components are engineered to interface seamlessly, guiding installers through a straightforward bolt in procedure that follows factory routing. By consolidating every necessary item, this design lets technicians focus on engine calibration rather than tracking down missing pieces.
