1968-1974 Corvette Y Body LS Fuel Delivery at 400 LPH

Achieve steady 400 LPH fuel delivery under boost in your 1968 to 1974 Corvette Y Body thanks to the efficient Walbro gerotor pump engineered for supercharged LS applications. Plug-and-play installation at OEM tank mounts combines smooth setup with American made durability, supporting 550+ hp without starvation while enhancing fuel efficiency and throttle response without structural modifications.

LS-Compatible EFI Fuel Tank Kit for 1968-1974 Chevy Corvette

When swapping an LS engine into a 1968-1974 Corvette chassis, securing precise fuel delivery under high demand is critical and this EFI fuel tank kit with a 400 LPH pump addresses that challenge head on. By leveraging a Walbro gerotor design and direct fitment to factory tank mounts, it eliminates the need for trimming or welding while delivering pulse free flow for supercharged and 550 plus horsepower applications. Installation is simplified with all necessary hardware included from the sending unit to the vent filter and gaskets, keeping the car's original underbody appearance intact. Produced in the USA under strict quality checks, each fuel tank assembly offers reliable operation in both spirited street driving and rigorous track sessions.

Gerotor Pump Mechanism Delivering Consistent Pressure

The core of this kit is a 400 LPH Walbro gerotor pump that employs inner and outer rotors to generate smooth, pulse free fuel flow. As the rotors mesh, they maintain a steady pressure that keeps pace with sudden throttle demands from supercharged or high output LS engines. This reliable design minimizes the risk of fuel starvation during rapid acceleration or extended track sessions. By handling flow rates up to 550 + horsepower, the pump ensures the engine always receives the volume it needs for optimal combustion. Its efficient operation also helps reduce electrical draw and heat buildup, contributing to longer service life.

Seamless Integration with Corvette Y Body Chassis

Engineered specifically for 1968-1974 Corvette applications, the tank module aligns perfectly with original Y Body frame rails and mounting points. This direct fit approach removes the need for cutting, trimming, or welding structural components, preserving the car's classic underbody appearance. The mounting brackets and filler neck have been shaped to follow the contours of the factory tank bay, ensuring consistent ground clearance and clearance for exhaust routing. By mirroring stock attachment points, it simplifies the installation process and shortens bench time, letting installers focus on final system checks rather than fabrication.

Comprehensive In Tank Module Enhancing System Reliability

Beyond the pump itself, the kit delivers a fully assembled in tank module complete with sending unit, tank straps, filler neck, vent filter, precision gaskets and all necessary hardware. Each component has been selected and tested to work together, eliminating compatibility issues and reducing the chance of leaks. The sending unit integrates seamlessly with GM-style EFI gauges, providing accurate fuel level readings under dynamic conditions. Quality sealing materials guard against contaminants and vapor escape, while the included vent filter ensures proper tank breathing without backflow. This complete package approach gives installers confidence that every detail has been addressed for dependable operation.

Domestic Craftsmanship Upholding Quality Standards

Produced in the USA under strict quality control protocols, every fuel tank kit undergoes dimensional inspection, flow testing and material validation before shipping. Domestic manufacturing allows for rapid response to engineering tweaks and spare parts requests, ensuring consistent delivery schedules. The steel tank and internal components are designed to withstand the vibrations, temperature variations and pressure cycles common to high output LS applications. This commitment to local production not only supports tighter tolerances but also offers outstanding customer support when maintenance or upgrades are required.
