1964-1967 Oldsmobile Cutlass LS and LT EFI Fuel Tank Kit
Retrofitting an LS or LT engine into a 1964 to 1967 Cutlass A Body demands consistent fuel delivery under sustained throttle loads. At the heart of this solution is a 400 LPH in-tank pump paired with a precision sending unit that matches the factory resistance curve for accurate level readings. Installation stays straightforward since the kit includes tank straps, vent filter and gaskets that align perfectly with original chassis openings without extra welding or cutting. Together these features support supercharged setups above 550 horsepower, preserve the Cutlass underbody appearance and maintain reliable operation mile after mile.
Steady Fuel Delivery for Supercharged LS and LT Engines
The core of this kit is a Walbro fuel pump rated 400 liters per hour, providing unwavering flow even under extreme throttle demands. By installing the module deep within the tank interior it remains cooled by surrounding fuel, which reduces thermal buildup and extends component life. This steady output easily supports engines that produce over 550 horsepower, preventing momentary pressure drops during rapid RPM increases or extended high load. The harmonious balance of flow rate and reliability makes this solution well suited for both street cruising and competition use.
Precision Level Sensing and Gauge Accuracy
A sending unit calibrated to the original Oldsmobile resistance curve ensures that your fuel gauge reads true from full to empty. Its float mechanism glides smoothly across a wide range of fuel depths, delivering repeatable resistance signals to the dash instrument. By mimicking stock electrical characteristics, this design eliminates erratic needle movement common with many retrofit systems. Drivers benefit from consistent, confidence inspiring feedback every time they glance at the gauge, without guesswork or last minute refuels.
Factory Fit Installation for 1964 to 1967 Cutlass A Body
This kit features a direct fit design that aligns with the chassis recess of Cutlass A Body models from 1964 to 1967, removing the need for special adapters or cutting. Included straps, gaskets, vent filter and filler neck hardware drop into the original openings with no extra fabrication required. All mounting points match the factory layout so you can secure the assembly using existing frame holes. By preserving the underbody styling and eliminating extra steps, installation time and labor cost are reduced considerably.
Domestic Manufacture Ensuring Component Reliability
Every major part of this kit is produced in the United States under rigorous quality control standards, reflecting a commitment to craftsmanship and consistency. The pump assembly and sending unit undergo extensive performance and durability testing before shipment. All hardware components meet industry specifications for corrosion resistance, ensuring they stand up to road grime and moisture. This focus on domestic sourcing and testing delivers peace of mind that each part will perform as intended over the long haul.
