EFI Fuel Tank Kit for 1968-1969 Chevy Chevelle LS and LT Swaps
Many custom 1968 and 1969 Chevelle A body builders upgrading to LS or LT engines find the factory fuel tank cannot maintain constant flow under modern injection demands. The 1968-1969 Chevelle EFI Fuel Tank Kit with 400 LPH pump directly addresses this by supplying 400 liters per hour, ideal for supercharged setups or engines over 550 horsepower. This bolt in, no modification required module mounts to original crossmembers and includes the in tank Walbro pump module, sending unit, filler neck, vent filter, tank straps, gaskets and all mounting hardware for installation that preserves underbody clearance and ensures consistent fuel delivery during high load driving.
Precision Fuel Delivery with 400 LPH Pump
The 1968 to 1969 Chevelle EFI Fuel Tank Kit with 400 LPH Pump features a Walbro pump engineered to deliver a consistent volume of fuel at up to 400 liters per hour. This capacity supports engines rated beyond 550 hp, including naturally aspirated and supercharged configurations. By maintaining steady pressure under acceleration and cornering loads, the system eliminates fuel starvation risks during spirited driving. The pump's internal regulator adapts in real time to demand, ensuring injectors receive the exact flow rate needed for optimal combustion. This translates to smoother throttle response, reliable power delivery, and reduced risk of knock under load.
Seamless Installation with MuscleRods Compatibility
Designed as a direct-fit solution for A-body chassis, this fuel kit installs into 1968 to 1969 Chevelle frames without any welding or cutting. Its flange pattern aligns precisely with factory mounting points, preserving original fuel line routing and chassis rigidity. In conjunction with MuscleRods engine mounts, the system guarantees correct engine placement and drivetrain angles. This partnership ensures the fuel tank sits at the ideal height and inclination, preventing pockets of air from entering the lines. Technicians will appreciate the drop-in nature of the design, which cuts installation time and preserves the vehicle's structural integrity.
Modern Engine Support and Domestic Craftsmanship
Whether you plan an LS or LT engine swap, this kit provides the necessary foundation for reliable fuel delivery. The tank and pump assembly accommodate modern fuel injection requirements, ensuring compatibility with factory ECM controls and aftermarket management systems. High-strength internal baffling prevents sloshing and maintains consistent suction, even under lateral G loads. Proudly manufactured in the USA, every unit undergoes rigorous leak and flow testing before shipment. This commitment to quality assures builders that each component meets tight tolerance standards and performance benchmarks expected in contemporary muscle car restorations.
This bolt in tank delivers reliable fuel flow for engines over 550 horsepower in LS and LT swaps without any modifications. To suit a smaller capacity fuel pump Kit at 255 LPH, see our 1968-1969 Chevelle EFI Fuel Tank Kit - 255 LPH Pump.
