If you're planning an LS swap on a classic 1958 Chevy Impala B-Body chassis the 1958 Impala EFI Fuel Tank Kit - 255 LPH Pump provides a precision built reservoir and pump assembly that installs without rail trimming. The corrosion resistant steel tank houses a 255 LPH Walbro fuel pump and delivers steady flow for engines up to 550 hp. The package includes a sending unit, filler neck, vent filter, tank straps, and all gaskets and hardware needed for a complete installation. By matching original bracket points this kit ensures reliable fuel delivery under sustained throttle conditions.
Seamless Integration with 1958 Chevrolet Classics
The 1958 Impala EFI Fuel Tank Kit - 255 LPH Pump is designed specifically for 1958 Bel Air, Biscayne, Del Ray and Impala models. Each tank contours precisely to the original floor pan geometry, preserving interior clearance and body alignment. Laser-formed mounting flanges match factory frame supports to eliminate custom fabrication and maintain structural rigidity. The filler neck retains stock location and venting provisions, ensuring authentic appearance while allowing modern electronic fuel injection capability. This tailored approach preserves original panel fitment, reduces bench time and maintains trunk floor strength without welding alterations.
Optimized Fuel Delivery for LS Engines
An integrated pump module inside the tank houses a 255 LPH Walbro unit and internal strainer. This arrangement delivers stable pressure and volume to support outputs up to 550 horsepower under heavy throttle and cornering loads. The modular assembly ensures consistent flow for popular LS power plants, from small displacement iron blocks to high output aluminum heads. A calibrated sending unit provides accurate level feedback to the dash gauge, eliminating erratic readings. Components are rated for extended service life and ease of maintenance, supporting reliable operation in daily drivers and weekend racers alike.
Complete Kit for Streamlined Installation
This kit includes the pump module preinstalled in the tank, an OE style sending unit, hardware pack, sealing gaskets and detailed instructions. Quick connect fittings simplify hose assembly and electrical terminals align with stock harness retainers for a clean fit. When paired with MuscleRods LS mounts, the assembly lines up precisely with the engine and transmission, preserving correct drivetrain angle and driveshaft alignment to reduce vibration and u joint wear. This cohesive solution eliminates component sourcing and makes it possible to complete the fuel system upgrade in a single installation session.
