1968-1974 Chevy Corvette LS EFI Fuel Tank Kit with 400 LPH Pump
When fitting an LS engine into a 1968 to 1974 Corvette Y Body maintaining reliable fuel flow under rapid throttle changes is vital so this EFI Fuel Tank Kit with its 400 LPH pump addresses that challenge. It mounts directly to original tank points and follows factory contours to eliminate trimming or welding and preserve the chassis profile. Each complete in tank assembly arrives with a Walbro gerotor pump sending unit vent filter precision gaskets and all necessary hardware for a tidy underbody layout. This assembly delivers consistent 400 LPH pressure to prevent fuel starvation in supercharged or 550 plus horsepower LS builds while supporting precise fuel level feedback.
Precision Gerotor Pump Architecture for Consistent 400 LPH Delivery
The heart of this fuel tank kit is a 400 LPH Walbro gerotor pump that relies on inner and outer rotors to generate smooth, pulse free flow at all engine speeds. This gear set design minimizes pressure fluctuations during sudden throttle inputs, ensuring the fuel rail remains pressurized even under the demands of supercharged or 550-plus horsepower LS configurations. By reducing flow turbulence and operating temperature, the gerotor mechanism extends pump life and helps prevent fuel vapor lock during spirited runs. Electrical demand is optimized to limit current draw and heat generation, while stable delivery enhances combustion efficiency by maintaining an accurate fuel-to-air ratio under dynamic load conditions.
Seamless Integration with Corvette Y Body Frame
Engineered exclusively for the 1968–1974 Corvette Y Body chassis, this assembly secures directly to the factory mounting points and follows the original tank contours to eliminate any trimming or welding steps. The filler neck and straps align precisely with the stock rails, preserving frame clearance and exhaust routing as designed at the factory. Installers benefit from a true plug and play solution that cuts installation time and reduces the risk of alignment errors. Maintaining the chassis profile also ensures consistent handling characteristics and original safety margins without unnecessary fabrication.
Comprehensive In-Tank Module Ensuring Leak-Free Operation
Every key component arrives preassembled into a unified in-tank module, including the pump, sending unit, vent filter, precision gaskets, straps, filler neck and mounting hardware. This holistic configuration eliminates potential gaps between separate parts that often cause leaks or premature failure. The calibrated sending unit is compatible with GM style EFI gauges to deliver accurate level readings even under high-G cornering or rapid acceleration. Robust sealing surfaces and a dedicated vent filter protect against vapor escape and contamination, delivering reliable performance in both street and track scenarios.
U.S. Crafted Durability Backed by Rigorous Testing
Manufactured in the United States under strict quality control protocols, each fuel tank module passes dimensional verification, flow rate testing and material inspections before leaving the plant. The steel tank body and internal components are validated to withstand vibration, pressure cycles and temperature swings typical of high-output LS applications. Local production enables rapid design refinements, quicker parts availability and direct technical support from the engineers who built the unit. This level of craftsmanship and traceability guarantees dependable operation in demanding environments and simplifies future service or upgrades.
