1968-1974 Chevy Corvette LS EFI Fuel Tank Kit with 255 LPH Pump
Swapping an LS into a classic Corvette demands a fuel system that matches the underbody, and this EFI fuel tank kit integrates a 255 LPH pump for direct fit on 1968 through 1974 Y Body chassis. By aligning with factory mounting points and preserving the stock filler and vent openings, the design avoids modifications and ensures proper line routing under spirited driving. It delivers consistent pressure for engines up to 550 hp and draws fuel from the tank bottom to minimize vapor lock during sustained wide open throttle runs.
Precision Alignment Using Factory Y-Body Mounts
The tank is sculpted to drop directly into the original cradle of the 1968 through 1974 Corvette chassis, relying on factory mounting points and precision CNC setup to match the stock filler and vent openings. By preserving the OE undercarriage geometry, this design prevents line binding and reduces strap stress during aggressive cornering. Maintaining the correct clearances also stops tank straps from flexing out of plane, eliminating a common source of metal fatigue over time. Each unit undergoes inspection for fit and finish before shipping to ensure a hassle-free installation that retains the car's stock profile.
Consistent Fuel Flow from Bottom-Drawing 255 LPH Pump
At the heart of this kit is a Walbro 255 liters per hour pump engineered to support engines up to 550 hp by holding pressure steady across a wide rpm range. Its bottom-drawing design draws cooler fuel from the tank's lowest point, boosting pump efficiency and extending service life compared with top-feed systems. An internal filter screen captures debris before it reaches the injectors, protecting the fuel rails and maintaining steady delivery under sustained wide-open-throttle runs. This level of consistency is critical for preventing vapor lock and fuel starvation when tuning for maximum output.
Seamless Integration with In-Tank Module Components
Rather than piecing together separate parts, this all-in-one kit combines the pump module, OE-style sending unit with float arm, vent filter, and filler neck into a single assembly. Included tank straps, gaskets, and hardware ensure every connection is vibration-resistant and leak-free, while the corrosion-resistant materials stand up to modern ethanol blends without swelling. By engineering these components to work as a cohesive system, the kit eliminates clearance issues and compatibility guesswork, saving hours in the garage. Each element is tuned to deliver accurate gauge readings and reliable operation in track conditions.
Step by Step Installation with OE Style Interfaces
The detailed instruction guide walks through tank removal, line routing, electrical hookups, and torque specs for each fastener, using clear illustrations and part call-outs to prevent common mistakes. OE-style connectors and float arm interfaces plug directly into the existing wiring harness, so there's no need for splicing or aftermarket adapters. Emphasis on proper gasket seating and correct strap tension keeps the system leak-free from startup through thousands of miles of spirited driving. Static pump testing procedures are included to verify pressure before firing the engine, ensuring safety and confidence at initial startup.
