LS EFI Fuel Tank Kit for 1966-1967 Chevy II/Nova X-Body
When swapping in an LS mill under a 1966 or 1967 Chevy II or Nova X-Body, maintaining stable fuel pressure can make or break performance and this EFI Fuel Tank Kit addresses that challenge. Designed to fit the original underbody profile, the complete module integrates a 255 LPH pump located inside the tank to ensure constant fuel supply during spirited acceleration or highway cruising. Installation uses factory mounting points and precision cut gaskets so no floor modifications are required and the classic underbody lines remain intact.
In Tank 255 LPH Pump Ensuring Steady Fuel Delivery
Centered within the tank, the 255 liter per hour Walbro pump ensures that LS engines up to 550 horsepower receive constant supply during rapid throttle transitions. Internal placement keeps the motor submerged, which cools the unit and reduces operational noise compared to external assemblies. Maintaining a stable stream prevents the pressure swings that can lead to hesitation under high demand. This direct feed supports consistent injector metering for cleaner combustion across a variety of driving conditions. The result is confident acceleration whether on an open highway or winding back roads.
Precision Fitment for Chevy II and Nova X Body Underbodies
This kit uses factory mounting holes on 1966 and 1967 Chevy II and Nova X Body frames to avoid any floor alterations. Custom cut sealing gaskets and original style hardware create a leak proof bond without altering the tank silhouette or ground clearance. The contours match the stock profile so suspension and exhaust components remain clear of interference. Installers find alignment and clearance concerns eliminated by the vehicle specific design. Final assembly preserves the classic underbody lines central to the car's period correct appearance.
Integrated Fuel Module Streamlines Installation
All critical components arrive pre assembled in a single module for a straightforward install process. From the pump and sending unit to the filler neck and vent filter, each part is engineered for direct interchange with the factory tank shell. The calibrated sending unit follows the original gauge curves to deliver accurate level readings under every load. A protective vent filter blocks moisture and debris, extending the service life of pump and lines. By reducing the number of loose parts and fabrication steps, installation time and potential leak points are minimized.
Classic Profile Preserved with Modern EFI Reliability
By integrating modern electronic fuel injection hardware without changing the external appearance, this kit merges period correct styling with contemporary performance. Consistent fuel pressure supports precise injector timing and smoother throttle response, which enhances drive quality in both city traffic and spirited runs. The invisible upgrade maintains factory aesthetics while delivering the reliability required by high output LS conversions. Drivers benefit from improved fuel economy and reduced risk of starvation at full throttle. This balance of form and function ensures the classic Nova or Chevy II retains its heritage look under every driving condition.
