1981-1988 Oldsmobile Cutlass G-Body LS EFI Fuel Tank Kit with 255 LPH Pump
When you transplant an LS powerplant into a Cutlass built between 1981 and 1988, ensuring steady fuel supply starts with the tank assembly. The Olds Cutlass EFI Fuel Tank Kit with its 255 LPH Walbro pump and integrated sending unit delivers consistent flow for engines up to 550 hp. Each component aligns with factory mounting points on the G Body chassis for a direct fit that cuts install time and removes the need for custom fabrication. Constructed from corrosion resistant materials, this kit stands up to daily miles and track sessions alike to keep your LS swap running dependably.
Precision Calibrated 255 LPH Pump Module
The in-tank fuel module combines the 255 LPH Walbro pump and sending unit into a single assembly engineered to support up to 550 hp. By housing both components together, internal turbulence and pressure fluctuations are minimized, ensuring a smooth and consistent fuel flow under rapid acceleration or high‐RPM conditions. This steady delivery is critical for accurate engine tuning and crisp throttle response during street cruising or track sessions. The integrated design also reduces the number of internal fittings, improving reliability and simplifying maintenance.
Chassis Specific Fitment for G-Body Cutlass
Every element of this kit is tailored to the factory mounting points on 1981–1988 Oldsmobile Cutlass G-Body frames, from the filler neck to the vent filter. The sending unit aligns precisely with the original tank opening, eliminating the need for custom brackets or line rerouting. This exact match not only cuts installation time but also lowers the chance of leaks or misalignment. Installers benefit from a bolt-in solution that delivers professional fitment without the hassle of fabrication.
Corrosion Resistant Construction for Longevity
The fuel tank, straps, and hardware are crafted from materials chosen for their resistance to corrosion and mechanical fatigue in daily driving and high‐load environments. High-quality gaskets and seals maintain leak-free joints even under constant thermal cycling and vibration. Whether the vehicle is on a long commute or pushed hard on the track, the assembly preserves its structural integrity. This durability safeguards consistent fuel delivery and reduces the need for premature replacement.
Integrated Fuel System Kit Simplification
This all-in-one EFI fuel tank kit includes the pump module, sending unit, tank straps, filler neck, vent filter, gaskets, and hardware required for a complete installation. Bundling these components ensures that each part is engineered to work together, removing any concerns about mismatched fittings or missing pieces. Builders gain confidence that every item meets exacting tolerances and quality standards. The cohesive package streamlines the swap process and lets you focus on performance rather than parts sourcing.
