1958 Chevy Impala EFI Fuel Tank Kit with 255 LPH Pump for LS Swap
When fitting an LS engine into your 1958 Impala on the factory B Body chassis, ensuring consistent fuel flow is crucial and the 1958 Impala EFI Fuel Tank Kit - 255 LPH Pump delivers just that. By slotting directly into the stock frame rails and featuring a in tank pump module with a powerful 255 LPH Walbro unit, it maintains stable pressure for engines up to 550 horsepower. All hardware from the sending unit to tank straps is included so you can complete the conversion without extra trips for parts.
Precision Fit for Stock B-Body Frame Rails
The fuel tank is shaped to match the original 1958 Impala B Body frame rails so installation slots in without cutting or welding. Engineered mounting points align with factory brackets and crossmembers to preserve chassis alignment and maintain proper ground clearance. The form of the shell also makes sure there is enough space around suspension links and exhaust tubing. This precision fit reduces setup time and helps keep the underbody profile as it was designed.
Submerged Pump Module Extends Service Life
Housing the 255 LPH Walbro pump inside the tank protects it from engine heat and minimizes the chance of vapor lock during hard driving. With continuous contact with fuel, the pump stays cool under load which helps prevent premature wear. A built in filter and connector reduce possible leak points and simplify wiring. This arrangement delivers quieter operation and more reliable performance across the RPM range.
255 LPH Flow Rate Ensures Consistent Pressure
Designed to support engines up to 550 horsepower, the 255 LPH pump maintains stable fuel volume even during full throttle acceleration or steep climbs. A consistent flow keeps the air fuel ratio within optimal range, avoiding lean spikes that can harm engine internals. Drivers will notice sharper throttle response and smoother power delivery at any engine speed. This steady output is critical for daily driving as well as performance runs.
Complete Kit Includes All Necessary Components
Every required part comes in the box, including the sending unit, tank straps, filler neck, vent filter, gaskets and mounting hardware. This eliminates trips to multiple suppliers and ensures all fittings match the tank geometry. Clear access to each fitting point means you can complete the swap in fewer steps. Having a full set of components on hand reduces assembly time and lets you focus on the engine installation itself.
