EFI Fuel Tank Kit with 255 LPH Pump for 1964-1967 Oldsmobile Cutlass LS Swap
Tackling the fuel delivery demands of an LS swap in a 1964-1967 Oldsmobile Cutlass starts with this EFI fuel tank kit featuring a 255 LPH pump. It installs at the factory mounting points under the trunk floor so you skip any cutting or welding on the chassis. The included Walbro pump sustains consistent flow for engines producing up to 550 horsepower while a precision sender delivers reliable gauge readings during spirited driving or long cruises. With precision fit and US built components this assembly preserves classic styling and delivers dependable performance for modern EFI conversions.
Walbro Pump Sustaining Consistent EFI Fuel Delivery
The 255 LPH Walbro pump inside this tank kit is engineered to provide a continuous stream of fuel able to support up to 550 horsepower without any drop in pressure. Its design uses an internal regulator and robust motor to maintain target pressure under high engine load, preventing lean spots that can harm performance or cause engine damage. By delivering steady volume even during rapid throttle changes, it ensures crisp response when accelerating from a standstill or overtaking at highway speeds. The pump housing is integrated directly into the tank assembly to shield the unit from road debris and heat soak, extending service life. In addition, optimized flow paths reduce turbulence and noise, making the entire system both reliable and quiet under heavy demand.
Precision Float Sender for Accurate Fuel Readouts
The precision sender included in this kit features a calibrated float arm that tracks fuel level with exceptional consistency, ensuring that dash gauge readings remain true even over bumpy roads. Its sealed housing resists exposure to ethanol blends and other modern fuels, which helps maintain accuracy over thousands of miles. A rugged pivot joint minimizes wear and guards against vibration damage, so you can trust the display during spirited driving or long highway stretches. Clean signal output aids the vehicle's computer in adjusting fuel trims, which can improve economy and reduce emissions. Overall, the sender removes the guesswork from planning long trips in a classic car swapped to EFI.
Factory Mount Alignment for Easy Installation
This fuel tank assembly is crafted to match the contours and mounting geometry of 1964 to 1967 Cutlass and 442 chassis points, allowing for a true drop in replacement. There is no need for any frame cutting or drilling, which preserves structural integrity and simplifies regulatory compliance. Included heavy gauge straps and OE style hardware secure the tank firmly against chassis flex, and all gaskets and seals align precisely to prevent leaks. Installation can be carried out with basic tools in a home garage, and most builders report completion times of just a few hours. The result is a clean under trunk appearance that retains the vehicle's original styling cues.
American Manufacturing and Quality Materials
Every component in the kit is produced in the USA under strict quality standards to ensure lasting performance and ease of service. The fuel tank shell uses corrosion resistant steel with a protective internal coating, guarding against rust even when exposed to modern ethanol blends. All sealing surfaces employ premium gasket materials that maintain a leak free seal through temperature cycles and vibration. Replacement parts such as straps, gaskets, and filters remain readily available from domestic suppliers, reducing downtime in the rare event of maintenance. This focus on local craftsmanship and supply chain control helps guarantee years of dependable service in a classic ride.
