1968-1974 Chevy Corvette LS EFI Fuel Tank Kit
Whether you are tackling a classic engine swap project or refining a street machine build this Corvette EFI fuel tank kit addresses the challenge of matching modern LS EFI requirements to the original underbody geometry. Designed for direct drop in to the 1968 through 1974 chassis it aligns with factory Y Body mounts and preserves stock filler and vent openings to ensure proper line routing without chassis alterations. Fuel delivery remains rock solid thanks to the high efficiency 255 LPH Walbro pump module that draws from the tank bottom and holds steady under sustained throttle runs for engines up to 550 hp. Installation follows a clear step by step guide and OE style connectors integrate with the factory wiring harness so no splicing is required for a clean, reliable setup.
Precision Fit with Original Chassis Mounts
The fuel tank shell is engineered to drop directly into the 1968 through 1974 Corvette frame using the factory mounting points, ensuring alignment with the original filler and vent openings. Computer controlled tooling sculpts each housing to match the underbody contours and preserve the stock geometry, preventing hose pinching or bracket interference during aggressive cornering. By maintaining the proper clearances, the design eliminates strap fatigue and reduces stress on support brackets over time. Every unit receives a thorough inspection for dimensional accuracy and finish quality before it leaves the shop, providing installers with confidence that no additional fabrication will be required.
Consistent Fuel Delivery from Bottom-Fed 255 LPH Pump
At the core of this kit is a Walbro 255 liter per hour pump capable of feeding engines up to 550 horsepower without pressure drop. Its bottom-fed inlet draws cooler fuel from the lowest point in the tank, improving pump efficiency and reducing the risk of vapor lock under wide open throttle conditions. An integrated filter screen traps debris before it can reach the injectors or fuel rails, helping to preserve component life and maintain smooth operation during extended high rpm runs. This steady delivery of fuel is essential for performance tuning, as it prevents lean spikes and keeps engine response consistent.
All-in-One In-Tank Module for Seamless Integration
Rather than sourcing multiple parts, this kit provides a complete in-tank assembly that includes the pump module, sending unit with calibrated float, vent filter, and filler neck. Each component is constructed from corrosion-resistant materials that stand up to modern ethanol blends, while precision gaskets and hardware ensure a leak-proof seal. By integrating these elements into a single unit, the design eliminates clearance conflicts and compatibility concerns common in retrofit applications. The unified assembly also offers accurate fuel level readings and vibration resistance, making it ideal for both street and track use.
Streamlined Installation with OE-Style Connections
The kit comes with a detailed installation guide that walks technicians through tank removal, fuel line routing, wiring, and torque specifications for all fasteners. Factory style connectors plug directly into the original wiring harness, eliminating the need for cutting or splicing and ensuring a reliable electrical connection. Clear instructions on gasket seating and strap tension prevent leaks, while provided tank straps and hardware secure the module firmly in place. Final static pump testing procedures verify output pressure before engine start, giving builders peace of mind at first fire-up.
