1978-1980 Oldsmobile Cutlass EFI Fuel Tank Kit with 255 LPH Pump for LS Swaps
If you are tackling an LS conversion in a 1978-1980 Oldsmobile Cutlass, proper fuel support is essential to prevent starvation under load or during hard acceleration. This EFI fuel tank kit pairs the original steel tank with a 255 LPH Walbro pump to maintain steady pressure for applications up to 550 horsepower. Each component installs into factory mounting points for a bolt-in fit that streamlines the LS swap and delivers dependable flow on both street and track drives.
Consistent Fuel Delivery for High-Powered LS Engines
The integration of a 255 LPH Walbro pump ensures steady pressure and volume for LS applications up to 550 horsepower. By maintaining precise flow rates under load and during rapid throttle changes, the system prevents fuel starvation that can cause hesitation or lean conditions. Its capacity to handle high demand translates into improved throttle response and consistent power delivery across the entire rev range. This level of support is crucial for both spirited street driving and track applications where fuel reliability cannot be compromised.
Precision Engineered for 1978-1980 Oldsmobile Cutlass Chassis
Each component of the EFI fuel tank kit is machined to align with the factory mounting points of the Cutlass fuel tank, providing a seamless upgrade without modifications to the chassis. The custom filler neck, vent filter, and tank straps conform to the original underbody contours, preserving the vehicle's stock appearance while delivering modern performance. This tailored approach reduces installation time by eliminating the need for fabrication, ensuring a secure fit and direct compatibility with existing fuel lines. Builders benefit from a straightforward process that integrates the new module almost exactly like the original equipment.
Premium In-Tank Module for Durability and Serviceability
The in-tank assembly houses the fuel pump, sending unit, and filter media within a robust module engineered for corrosion resistance and vibration control. Walbro's proven pump design delivers consistent flow and long service life under high thermal and load conditions. Included gaskets and mounting hardware are selected for fuel resistance and repeatable sealing, minimizing the chance of leaks over extended use. With components built to precise tolerances, this kit provides reliable operation and simplified maintenance intervals that uphold the Cutlass's reputation for durability.
