1968-1974 Chevy Corvette Y-Body LS EFI Fuel Tank Kit with 400 LPH Pump
When fitting an LS powerplant into a classic 1968 to 1974 Corvette Y Body maintaining steady fuel supply during hard throttle transitions is essential so this EFI Fuel Tank Kit with a 400 LPH pump addresses that need by mounting directly to factory tank bosses and tracing the original contours for a precise fit. Installers will appreciate how it secures without cutting or welding to preserve underbody clearance and airflow. Its Walbro gerotor design delivers pulse free flow that resists vapor lock even in supercharged or 550 plus horsepower LS setups. Every module arrives ready to install with the sending unit vent filter seals and hardware required to ensure accurate level readings and leak free performance. Precision gaskets and steel body construction ensure a reliable sealed environment that stands up to vibration and temperature changes typical of high output LS applications.
Gerotor Pump Design for Smooth Fuel Delivery
The kit centers on a 400 LPH Walbro gerotor pump that uses an inner and outer rotor to deliver smooth and consistent fuel flow at all engine speeds. This design minimizes pressure swings during rapid throttle transitions, maintaining rail pressure even in more than 550 horsepower supercharged LS engines. Reduced turbulence and operating temperature not only guard against vapor lock but also extend service life of the pump. Electrical draw is optimized to prevent heat build up, and steady delivery supports precise fueling and engine response under hard acceleration.
Seamless Mounting to Original Corvette Y Body
Engineered to attach directly at factory tank bosses, the assembly follows the original 1968 to 1974 Corvette Y Body contours. This alignment removes any need for trimming or welding, preserving underbody clearance and exhaust path as designed. Installers save hours on fabrication and reduce alignment errors with this plug in and play approach. Keeping the chassis profile intact helps maintain handling balance and crash safety margins established by the original frame design.
All In Tank Module for Leak Free Operation
Each component arrives pre assembled into one in tank module, including pump, sending unit, vent filter, gaskets, straps and filler neck. By unifying these elements, the design eliminates potential leak points and ensures a reliable seal under vibration and temperature swings. The calibrated sending unit works with GM EFI gauges to give accurate level readings during hard cornering or rapid acceleration. A dedicated vent filter keeps contaminants out and supports consistent performance on both street and track.
Built in USA Steel Construction for Lasting Durability
Manufactured in the United States under strict quality controls, this fuel tank assembly features a robust steel body engineered to endure vibration, pressure cycles and temperature extremes typical of powerful LS installations. Local production means each unit is verified for dimensional accuracy and flow rate before shipping. This process allows rapid design updates and direct technical support from engineers with hands on knowledge of the product. The result is a durable assembly that simplifies future service and upgrades.
