1968 Impala EFI Fuel Tank Kit with 400 LPH Pump
When dropping an LS mill into a 1968 Impala chassis, consistent fuel delivery under sustained throttle becomes mission critical and the 1968 Impala EFI Fuel Tank kit with 400 LPH Pump addresses that need with precision. Its stamped steel shell matches the B Body frame rail contours to maintain factory mounting points without cutting the floor pan and reduces installation guesswork. By integrating the Walbro 400 liter per hour module with sender and internal filter, installers can achieve exact pressure control and consistent fuel delivery during spirited driving with minimal complexity. Installers will find that the complete hardware package including straps, filler neck and vent components ensures a single session swap that brings reliable injection performance to your classic Impala.
Precision Stamped Steel Shell for Exact Fitment
The fuel tank is fabricated from heavy gauge steel that follows the 1968 B Body frame rails without alteration to the floor pan. This precise stamping preserves all factory mounting points, ensuring the assembly installs flush and maintains chassis integrity. Fully welded seams are sealed to resist leaks and protect against corrosion from road moisture. By matching the original contours, the tank reduces vibration, minimizes drivetrain noise, and delivers a seamless integration with the Impala's structure.
Integrated In Tank Fuel Module for Streamlined Operation
By uniting the pump, sending unit and internal filter into a single module, the system dramatically cuts plumbing complexity and installation time. The sender sits at an optimal height within the reservoir, offering accurate fuel level readings under rapid acceleration or steep inclines. A sock filter traps debris before it reaches the pump, extending service intervals and safeguarding critical components. Corrosion resistant electrical connectors complete the assembly, ensuring stable signal transmission between the tank and the gauge cluster.
400 LPH Pump Capacity for Steady Fuel Pressure
The Walbro 400 liter per hour pump is engineered to meet the demands of naturally aspirated or boosted LS conversions producing up to 750 horsepower. Mounted inside the tank, it remains immersed in fuel, which acts as a coolant to prevent overheating during sustained operation. This generous flow rate maintains consistent pressure at high engine speeds, eliminating the risk of lean conditions and hesitation. Drivers benefit from smooth throttle response and reliable delivery during extended spirited runs or highway cruising.
Comprehensive Kit Components for Single Session Installation
This all inclusive package features tank straps, a filler neck, vent filter, gaskets and all mounting hardware needed for a direct swap. Preassembled brackets align precisely with factory holes, guiding installers step by step from fuel line disconnection to final torque verification. The included instruction guide walks through each phase of the swap, reducing guesswork and avoiding trips to the parts store. With everything in one box, the new tank can be installed in a single workday, bringing modern injection reliability to the classic Impala.
