EFI Fuel Tank Kit with 255 LPH Pump for 1964-1967 Oldsmobile Cutlass LS Swap
When upgrading a 1964-1967 Oldsmobile Cutlass with an LS powerplant, maintaining stable fuel supply under increased demand is crucial, and this EFI Fuel Tank Kit with an integrated 255 LPH pump delivers the precise flow needed for modern EFI conversions. Featuring direct fit mounting at the factory trunk points, it bypasses any chassis modifications and preserves the car's original underbody lines. The tank assembly houses a US built Walbro unit that keeps pressure steady through rapid throttle changes, while the precision sender delivers accurate readings to the dash gauge. In addition, its corrosion resistant shell and OE style straps ensure leak free performance without the need for any frame cutting or welding.
Optimized Internal Flow Paths for Even Fuel Delivery
This fuel tank kit employs carefully shaped internal passages that guide liquid from the pump to the outlet with minimal disturbance. By reducing turbulence inside the tank, this design ensures a consistent supply even during rapid throttle transitions, which translates into smoother acceleration and more precise engine response. The gentle curves and strategic channel dimensions help maintain steady pressure, preventing air pockets or fuel surges that can lead to lean running. In turn, improved flow efficiency supports better fuel economy under everyday driving conditions. This refined distribution network showcases how subtle geometry choices within the tank assembly deliver a tangible performance advantage for an LS conversion.
Integrated Vent Filter and Filler Neck for Reliable Pressure Control
The inclusion of a dedicated vent filter and custom filler neck assembly helps maintain proper tank breathing, preventing vacuum lock and fuel starvation under hard cornering or steep gradients. A fine media element in the vent filter blocks contaminants from entering while allowing air to escape freely as fuel is drawn. The filler neck aligns perfectly with the trunk opening to ensure clean routing and a secure seal that minimizes evaporation losses. This attention to venting detail means the fuel system remains balanced, safeguarding pump life and engine health over thousands of miles. As a result, drivers can push their LS engines to the limit without worrying about intermittent fuel dropouts.
Service Ready Components for Quick Access and Replacement
The modular design of the pump module and sender unit allows for rapid removal from the top of the tank, eliminating the need to lower the entire assembly for routine service. All critical seals and filters are included in the kit, and hardware such as straps, gaskets, and vent elements share standardized dimensions for easy sourcing. This approach means preventive maintenance can be carried out in a home garage with basic tools, reducing time spent under the car and keeping repair costs low. In the unlikely event of component wear or failure, replacement parts remain available through domestic suppliers, ensuring limited downtime. The focus on serviceability reflects an understanding that classic cars benefit most when vintage style meets practical upkeep.
Seamless Trunk Fitment Preserving Classic Underbody Appearance
Careful engineering of mounting brackets and tank contours ensures that the kit drops directly into the original trunk cavity without any cutting or welding of the body or frame. The factory anchor points and OE style straps secure the unit exactly where the heritage fuel tank once sat, preserving the car's factory underbody profile. This means that once installed, there are no telltale modifications visible beneath the decklid, leaving the classic lines intact. Neat integration of the filler neck and vent plumbing further contributes to an uncluttered trunk area. Enthusiasts can enjoy modern EFI performance while retaining the authentic appearance that makes a 1964-1967 Cutlass so distinctive.
