1970-1972 Oldsmobile Cutlass A-Body LS EFI Fuel Tank Kit 255 LPH Pump
When installing an LS series engine into a 1970 to 1972 Oldsmobile Cutlass A Body platform, the Cutlass EFI Fuel Tank Kit with 255 LPH Pump provides a fully integrated fuel delivery solution to support up to 550 horsepower without trimming the frame rails. This 255 LPH Walbro electric fuel pump resides in a molded tank that follows the factory underbody contours and secures to spot welded pads using included tank straps. Preformed stainless steel lines and a precision filler neck eliminate extra fittings, while the pump module, sending unit, vent filter, gaskets and hardware deliver a complete Made in USA package compatible with returnless and traditional systems.
Complete Fuel Delivery Solution
The 1970 through 1972 Cutlass EFI Fuel Tank Kit with 255 LPH Pump delivers a turnkey fuel system for GM A Body Cutlass conversions. The steel tank is contoured to use factory frame rail attachment points, preserving original ride height and chassis clearance. For custom installations the tank also accepts optional MuscleRods rail adapters, ensuring precise alignment of inlet and outlet ports and maintaining proper routing angles for fuel and vent lines. This approach eliminates guesswork and supports reliable operation under spirited driving conditions.
Engineered for Peak LS Performance
This kit supports engine outputs up to 550 horsepower, making it suitable for aggressive street and track LS builds. The high-performance 255 LPH Walbro electric pump delivers steady flow and pressure during hard acceleration and cornering, reducing the risk of lean spots. It accommodates both returnless systems that simplify plumbing and traditional return style configurations for those seeking fine tuning. All fittings match common LS swap layouts, streamlining the transition from carbureted delivery to modern electronic fuel injection.
Installation and Material Excellence
Fabricated from heavy gauge steel with a corrosion resistant finish, the tank stands up to road chemicals and environmental exposure. The inlet and outlet bosses accept 3/8 inch or 5/16 inch stainless steel lines, giving installers freedom to choose from a wide range of aftermarket hose kits. A molded fill neck and factory style lock ring make use of existing fuel caps, while the included mounting straps and hardware reduce installation time. Each unit is assembled and tested in the USA to verify leak free performance.
Warranty and Technical Support
Every fuel tank kit ships with detailed instructions and a parts checklist to confirm compatibility before installation. Dedicated technical support specialists are available to address questions on plumbing options, bracket selection and system bleeding procedures. A one year limited warranty covers manufacturing defects, providing peace of mind and ensuring that your Cutlass project will receive reliable service mile after mile.
