1969-1970 Impala EFI Fuel Tank Kit with 255LPH Pump
If you're installing an LS engine into a 1969-1970 Impala B body, this EFI fuel tank kit with 255 LPH pump solves clearance conflicts beneath the trunk by reshaping the module to match factory strap locations without fabrication. The module sits three quarters of an inch deeper and five inches shorter than stock to preserve trunk space and ride height, while the submerged Walbro pump prevents vapor lock and holds steady pressure for up to 550 hp. Constructed from heavy gauge galvanized steel with a full powder coat, the tank resists corrosion from ethanol blends and dampens vibration for a quieter cabin. The package includes molded gaskets, OE style straps, filler neck and precision hardware for a bolt in solution that fits factory points for LS swaps with no custom brackets required.
Precision Fit for Classic Impala B Body Chassis
The fuel tank module is reshaped to sit three quarters of an inch deeper and five inches shorter than the original unit, ensuring it slides beneath the trunk floor without reducing ground clearance. Laser-verified flange locations align perfectly with the stock strap points on a 1969 to 1970 Impala B Body, so there is no need for welding or custom supports. By preserving both ride height and cargo volume, this design upholds the vehicle's factory proportions while eliminating clearance conflicts. Machined contact surfaces around each mounting pad damp vibration and prevent noise transmission into the cabin for a quieter ride. Installers achieve a seamless, factory correct appearance and maintain structural integrity of the chassis sheet metal.
Submerged Walbro Pump Prevents Vapor Lock and Delivers Steady Flow
Positioning the Walbro 255 LPH pump fully under fuel creates a consistent cooling environment that guards against vapor lock during high stress operation. Rated to support up to 550 horsepower, this immersion setup sustains stable pressure from idle through full throttle, reducing the risk of fuel starvation under load. Integrating the sending unit within the same assembly streamlines fuel line runs and wiring harnesses, minimizing potential leak points and simplifying system diagnostics. The submerged location also helps muffle pump noise, providing crisp throttle response without audible whine. Enthusiasts can push their LS engine swaps with confidence, knowing the fuel delivery remains rock steady in all driving conditions.
Galvanized Steel Shell with Complete Powder Coat Defense
Constructed from heavy gauge galvanized steel, the tank shell forms a robust barrier against moisture, road salt and ethanol-enhanced fuels. A full powder coat finish locks onto every contour, sealing weld seams and cut edges to keep corrosion at bay. This protective layer not only extends service life in harsh environments but also dampens vibration and underbody noise for a quieter interior. Routine visual inspections reveal the coating condition instantly, reducing maintenance downtime. Owners benefit from enhanced durability and peace of mind, even when using modern high-ethanol blend gasoline.
All-In-One Kit Streamlines Bolt In Installation
This comprehensive kit brings together the in-tank pump module, sending unit, molded gaskets, filler neck, vent filter, OE-style straps and precision hardware in one package. Each component is engineered to mate seamlessly with the factory mounting points on the Impala B Body chassis, eliminating the need for custom brackets or extensive modifications. The included vent filter ensures proper tank breathing while the precision-cut gaskets deliver a leak-free seal. By supplying every part required for the conversion, technicians spend less time sourcing parts and more time calibrating the EFI system. Whether in a home garage or professional shop, installers achieve a neat, professional grade fit and a reliable fuel system ready for spirited driving.
