1968-1974 Chevy Corvette LS EFI Fuel Tank Kit with 255 LPH Pump
When installing an LS engine into a 1968 to 1974 Corvette Y Body chassis the 1968 to 1974 Corvette EFI Fuel Tank Kit 255 LPH Pump addresses one of the swap's most critical needs by providing reliable fuel delivery. It uses factory mounting points to fit directly into the original cradle without drilling or reshaping and preserves the stock filler and vent locations. The integral sending unit delivers accurate gauge readings while the 255 LPH Walbro pump maintains steady flow up to 550 horsepower even during extended wide open throttle runs. Installation hardware and a detailed guide are included to simplify each stage of the swap and help avoid last minute parts hunts.
Engineered Fit for 1968-1974 Corvette Y Body Chassis
This fuel tank kit is sculpted to ride in the original cradle of a 1968-1974 Corvette Y Body without any modification to the frame or tub. By using the factory mounting points and precision CNC validation, the tank aligns exactly with the stock filler opening and vent locations, preserving the underbody geometry. Maintaining the factory clearances prevents fuel line binding and strap stress in tight cornering or spirited driving. The result is a seamless installation that respects the classic chassis layout while accommodating modern LS power.
Consistent Fuel Flow with 255 LPH Walbro Pump
At the heart of this conversion lies a 255 liters per hour Walbro pump engineered to support engines up to 550 horsepower under sustained throttle. Its internal diaphragm mechanism holds fuel pressure steady across a wide range of engine speeds, reducing the risk of vapor lock and fuel starvation on long acceleration runs. Drawing from the bottom of the reservoir helps keep incoming fuel cooler, which boosts pump efficiency and prolongs service life. Drivers can count on uniform delivery whether cruising through traffic or pushing hard on the track.
Integrated Kit Components for Streamlined LS Swap
Every element in this all-in-one package is designed to work together without fitting conflicts. The in-tank pump module and sending unit combine to provide accurate gauge readings and reliable flow, while the vent filter and filler neck attach directly to the factory lines. Included straps, gaskets and fasteners ensure a secure mount that resists vibration and leaks. By unifying these parts in a single kit, you avoid the guesswork of matching components and cut hours off the build time.
Step by Step Guide for Smooth Installation
The detailed instruction manual breaks the process into clear stages, guiding you through tank removal, line routing, wiring connections and torque specifications for every fastener. Illustrations show correct vent filter placement and harness orientation to eliminate common mistakes. Whether you're an experienced technician or tackling your first LS swap, the consistent format and clear callouts help you work quickly and accurately. Emphasis on proper sealing and strap tension makes sure the system remains leak free from initial startup to many miles down the road.
