1968-1974 Chevy Corvette Y-Body LS EFI Fuel Tank Kit with 400 LPH Pump
If you are fitting an LS engine into a 1968 to 1974 Corvette Y Body chassis this 1968 to 1974 Corvette EFI Fuel Tank Kit with its 400 LPH Pump ensures consistent fuel delivery under demanding conditions. It relies on a Walbro gerotor mechanism and direct mounts that align with factory tank points to deliver pulse free flow without trimming or welding. Each kit arrives complete with sending unit vent filter precision gaskets and all hardware for a clean underbody appearance. American made under strict quality checks this assembly endures spirited street use and rigorous track sessions.
Gerotor Pump Mechanism Delivering Steady High Volume Flow
The core of this kit is a 400 LPH Walbro gerotor pump that uses rotating inner and outer gears to maintain consistent pressure under sudden throttle changes. The gerotor design produces pulse free delivery that keeps pace with the demands of supercharged or 550 plus horsepower LS engines. By smoothing out flow and reducing heat buildup, the pump lowers the risk of fuel starvation during spirited runs or track use. Electrical output is optimized to reduce current draw and extend service life. This precise delivery also enhances combustion efficiency by ensuring the correct fuel to air ratio at all times.
Direct Integration with 1968 to 1974 Corvette Y Body Chassis
Specifically engineered for the Corvette Y Body frame, this fuel tank module aligns precisely with factory mounting points and rails. The filler neck and mounting brackets match the original contours, avoiding any need for trimming or welding. This approach preserves the car's classic underbody look while ensuring correct ground clearance and exhaust routing. Installers save time and bench hours by securing a direct fitment solution that simplifies system checks and final adjustments. By eliminating fabrication steps, the kit also reduces installation errors and maintains factory safety standards.
Complete In Tank Assembly for Reliable Operation
Every component is supplied to form a fully integrated in tank solution, including the pump module, sending unit, filler neck, vent filter, gaskets, straps and hardware. This complete assembly eliminates compatibility gaps that can lead to leaks or pump failure. The sending unit is calibrated to work with GM style EFI gauges for precise fuel level reading under dynamic conditions. Quality seals prevent vapor escape and guard against dirt ingestion, supporting trouble free performance. An integrated vent filter maintains proper tank breathing without backflow risk, protecting the pump and engine from fuel vapor lock.
American Made Quality with Rigorous Inspection
Each tank assembly is produced in the United States under strict quality control protocols, undergoing dimensional checks, flow testing and material validation before shipment. Local manufacturing ensures rapid adaptation to engineering updates and prompt spare part availability. The steel tank and internal parts are designed to resist vibration, temperature changes and pressure cycles common to high output LS setups. By keeping production local, engineers can maintain tighter tolerance control and offer direct technical support when maintenance or future upgrades are required. This local craftsmanship guarantees consistency, support and durability in spirited street or track conditions.
