EFI Fuel Tank Kit with 255 LPH Pump for LS Swap on 1968-1974 Chevy Corvette
For Corvette LS engine swaps in the 1968 through 1974 Y Body chassis the 1968-1974 Corvette EFI Fuel Tank Kit with 255 LPH Pump delivers exact alignment with factory mounting points and ensures dependable fuel supply without any modifications. By retaining the original filler and vent locations this kit preserves the underbody layout and simplifies installation while reducing the risk of line binding or strap stress during spirited cornering. The integrated sending unit offers accurate gauge readings and the 255 LPH Walbro pump maintains constant flow for engines up to 550 hp under prolonged wide open throttle conditions preventing vapor lock and fuel starvation.
Precision Fit for 1968 to 1974 Corvette Y Body Chassis
The EFI fuel tank is sculpted to sit in the factory cradle of a 1968 to 1974 Corvette Y Body without any alteration to the frame or tub. By relying on the original mounting points and precision CNC set up, the tank aligns exactly with the stock filler opening and vent locations, preserving the underbody geometry and maintaining factory clearance. This exact alignment prevents fuel line binding and strap stress during tight cornering or aggressive driving. Matching the factory clearances also keeps the tank straps from flexing out of plane, which can lead to metal fatigue over time. Each unit is inspected to confirm the finish and fit aspects before shipment, ensuring a trouble free install experience that retains the car's original underbody profile.
Stable Fuel Delivery with 255 LPH Walbro Pump
At its core a 255 liters per hour Walbro pump is engineered to support engines up to 550 horsepower under sustained throttle. Its diaphragm style design holds fuel pressure steady across a wide range of engine speeds, reducing the risk of vapor lock and fuel starvation on long acceleration runs or extended high speed sections. Drawing from the bottom of the tank helps keep incoming fuel cooler which boosts pump efficiency and extends service life significantly compared to top draw systems. The internal filter screen traps debris before it reaches the main injector rails, protecting the entire fuel system from premature wear. Drivers can count on uniform delivery whether cruising through traffic or pushing hard on the road course. This level of consistency is vital when tuning for max output or running on pump fuel near its performance limit.
Integrated Kit Components for Seamless LS Swap
Every element of this all in one package is designed to work together without fitting conflicts or clearance issues. The pump module and sending unit provide accurate gauge readings by using an OE style float arm and circuit board, while the vent filter and filler neck attach directly to existing lines for a clean install. Included straps gaskets and hardware ensure a secure mount that resists vibration and fuel leaks even under track conditions. By combining these parts in a single kit you avoid the guesswork involved in sourcing compatible components and save hours on the assembly process. The kit components are corrosion resistant and designed to withstand exposure to modern ethanol blends without swelling or degradation.
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 that can lead to leaks or pump failure. Whether you are an experienced technician or taking on your first LS engine conversion the clear call outs and part numbers help you work quickly and accurately. Emphasis on proper gasket sealing and strap tension ensures the system remains leak free from initial startup to many miles down the road. The manual also includes tips on testing the pump under static conditions and verifying pressure before firing the engine. Safety notes remind you to depressurize the fuel system and wear proper eye protection when handling chemicals.
