1969-1970 Impala EFI Fuel Tank Kit with 255 LPH Pump
If you are converting a 1969 or 1970 Impala to EFI, this kit ensures a dependable fuel feed by pairing a 255 LPH Walbro pump with a sealed in tank module. Engineered to fit stock mounting points, the assembly slides beneath the trunk floor for a fuss free installation that preserves ground clearance. Galvanized steel construction with powder coat protection resists corrosion while the modified tank profile boosts capacity without affecting strap alignment. Support for LS engine swaps is built in, avoiding the need for custom brackets or welding.
Robust Fuel Flow for Up to 550 Horsepower
The 255 LPH Walbro pump is calibrated to maintain a steady fuel volume even when engine demand peaks, ensuring smooth throttle response under heavy load. By remaining submerged in the sealed tank module, the pump gains constant cooling that lowers the risk of vapor lock during spirited driving. Its precise pumping capacity holds fuel pressure stable, preventing hesitation at wide-open throttle and supporting consistent power delivery. Integrating both pump and sending unit in one housing streamlines installation and minimizes potential leak points. Its wide compatibility with LS engine conversions further simplifies system integration for modern powerplants.
Custom Tank Geometry for Seamless Impala Installation
The fuel tank has been reshaped to sit three-quarters of an inch deeper and five inches shorter than the factory unit, boosting capacity without sacrificing ground clearance. Precision laser measurements ensure the module aligns perfectly with original strap locations, eliminating the need for bracket modifications. This exact fit provides a snug underbody profile, reducing vibration noise and keeping the assembly secure under all road conditions. Installers benefit from a true bolt-in replacement that matches the trunk floor contours for a quiet, stable ride.
Galvanized Steel Shell with Durable Powder Coat Protection
A heavy-gauge galvanized steel tank shell offers exceptional resistance to rust and corrosion, even when exposed to moisture and ethanol-blended fuels. An industrial-grade powder coat layer bonds tightly to the metal surface, forming a tough barrier against abrasion and chemical attack. Together, these treatments safeguard weld seams and cut edges from pitting, significantly extending tank service life. The finish also helps dampen sound transmission, contributing to a quieter cabin environment on long drives.
All-Inclusive Kit Components Streamlining Installation
Every element needed for a complete EFI conversion is included, from the in-tank fuel pump module and sending unit to molded gaskets, vent filter, filler neck, tank straps, and installation hardware. Factory-style straps and precision-cut gaskets ensure a leak-free seal and solid mounting against the trunk floor. The vent filter keeps debris out of the module while the OE-matched filler neck prevents spills during refueling. This comprehensive package reduces parts hunting and lets technicians focus on calibration rather than fabrication.
