1967 Impala EFI Fuel Tank Kit with 255 LPH Pump
Swapping an LS or LT engine into a classic 1967 Impala demands a fuel supply that can keep pace with modern powerplants. The 1967 Impala EFI Fuel Tank Kit - 255 LPH Pump installs directly into the factory location used by 1965 to 1966 Impala tanks and aligns precisely with the B body frame rails without trimming. Crafted from stainless steel, its sump is 0.75 inch deeper and overall length is shortened by 5 inches for chassis clearance while adding fuel capacity. An in-tank module houses the 255 LPH Walbro pump plus the sending unit, vent filter and delivers consistent EFI fuel delivery up to 550 hp. Gaskets, mounting hardware, filler neck and straps are included for a straightforward bolt in solution.
Precision Fitment and Profile Optimization
The 1967 Impala EFI Fuel Tank Kit has been engineered with a five inch reduction in front to back length to match the original location in the B body chassis without requiring any modification to the floor pan or fuel lines. This compact profile ensures that the tank clears the driveshaft and spare tire well exactly as the factory design intended, preserving trunk space and preventing interference under load. When used in conjunction with MuscleRods mounting hardware, this tank aligns precisely with existing frame rails and suspension points, maintaining the correct engine position and drivetrain angles for reliable operation at all rpm ranges.
Enhanced Fuel Capacity and Delivery
By increasing the tank depth by three quarters of an inch, this kit offers a meaningful boost in fuel capacity compared to the original assembly. The additional volume helps reduce the frequency of refueling stops on highway runs or track outings, making it ideal for high output builds. At the heart of the system lies a 255 LPH Walbro pump calibrated to support up to 550 horsepower. Its consistent flow rate under high demand prevents fuel starvation during sustained full throttle or cornering, safeguarding engine performance and tuning accuracy for modern EFI management systems.
Durable Construction and Chassis Integration
Constructed entirely from 304 grade stainless steel, this fuel tank resists corrosion caused by ethanol blends and road contaminants, ensuring years of reliable service without swelling or rust. Every weld is precision crafted to factory tolerances, delivering a leak free envelope that meets quality standards. The kit’s custom build for the 1967 Chevy Impala B body chassis guarantees a seamless installation process and solid footing against frame movement. Compatibility with MuscleRods mounting components adds another layer of stability, locking the tank in place to prevent shifting during hard launches or emergency maneuvers while maintaining ideal fuel pickup orientation.
