EFI Fuel Tank Kit with 255 LPH Pump for 1969-1970 Impala
Installing an EFI system in a 1969 to 1970 Impala often runs into clearance and mounting issues but this EFI Fuel Tank kit with 255 LPH Pump reshapes the module to match factory strap locations. The tank sits three quarters of an inch deeper and five inches shorter than stock to preserve trunk space and ride height while accommodating LS swaps without welding or custom brackets. A fully submerged 255 LPH Walbro pump prevents vapor lock and maintains stable pressure for engines up to 550 hp. Constructed from heavy gauge galvanized steel with powder coat protection, the shell resists corrosion from ethanol blends and dampens noise and the complete package includes molded gaskets, filler neck, OE style straps and precision hardware for a streamlined install.
Precision Fit for Classic Impala B Body Chassis
This EFI fuel tank reshapes the stock profile to sit three quarters of an inch deeper and five inches shorter than the original unit, ensuring it aligns perfectly beneath the trunk floor without altering ground clearance. Laser-verified mounting flanges match the factory strap locations on the 1969 to 1970 Impala B body, eliminating the need for welding or custom brackets. By preserving the vehicle's ride height and trunk storage volume, installers achieve a seamless integration that looks and feels factory correct. The machined contact surfaces also dampen vibration and prevent rattles, delivering a quiet, rock-solid installation.
Submerged 255 LPH Pump Performance Stability
Positioning the Walbro 255 LPH pump fully under fuel prevents vapor lock and keeps the unit cool during sustained high engine loads. Operating submerged inside the sealed module allows it to maintain consistent pressure from idle through wide open throttle, supporting up to 550 horsepower without hesitation. Integrating the sending unit in the same assembly streamlines fuel lines and wiring, reducing potential leak points and simplifying troubleshooting. The result is a crisp throttle response and rock-steady fueling under spirited driving conditions.
Corrosion Resistance from Galvanized Steel and Powder Coat
Constructed from heavy gauge galvanized steel, this tank forms a rugged barrier against corrosion and chemical attack from ethanol blends commonly found in modern fuels. The uniform powder coat finish bonds to every contour, sealing weld seams and cut edges against moisture, abrasion, and road salts. In addition to protection, the coating helps dampen sound transmission through the tank walls, creating a quieter cabin environment. Owners can rely on visual inspections alone to confirm integrity, extending service intervals and reducing maintenance costs.
Complete Hardware and Components for Streamlined Installation
This all-in-one kit brings together the in-tank pump module, sending unit, OE-style straps, molded gaskets, filler neck, vent filter, and precision hardware into a single package. Each component is engineered to work in concert, ensuring a leak-free, bolt-in solution that fits factory mounting points without modification. By supplying every part needed for the conversion, technicians spend less time sourcing items and more time dialing in EFI calibration. Whether performed in a home garage or professional shop, the streamlined process reduces installation time and complexity while supporting reliable fuel delivery for LS engine conversions.
