LS EFI Fuel Tank Kit with 255 LPH Pump for 1958 Chevy Impala B-Body
Taking an LS powerplant from the blueprint to the road in a 1958 Impala often stalls without a dependable fuel source and the 1958 Impala EFI Fuel Tank Kit - 255 LPH Pump addresses that by fitting directly between the frame rails while protecting ground clearance. The tank carries an integrated pump module that houses a reliable 255 LPH Walbro unit to sustain consistent pressure for engines up to 550 hp. Installation becomes straightforward thanks to factory mounting bosses, matched straps, gaskets and fittings that allow installers to complete the job without trimming or extra parts runs.
Precision Fitment for 1958 Chevy B Body Frame Rails
The fuel tank is molded to match the original rails on a 1958 Chevy Impala B Body chassis, allowing it to seat cleanly without cutting or welding. Factory bosses align directly with existing brackets and crossmembers, preserving ground clearance and underbody geometry as designed by Chevrolet. This exact positioning keeps belt and pulley clearances at the rear of the LS engine in spec while preventing interference with suspension or exhaust components. By replicating the stock layout, installation time is minimized and the car's handling balance remains true to factory intentions.
In Tank Pump Module for Enhanced Reliability
The integrated pump module houses a 255 LPH Walbro unit entirely within the tank shell to maintain continuous immersion in fuel. This submersion cools the pump motor and reduces the chance of vapor lock under heavy load or high temperature conditions. A built‐in mesh filter protects the impeller from debris, while a single plug connector simplifies wiring and seals the system against leaks. Housing all components inside the tank also keeps noise levels down and delivers a more consistent pressure signal to the fuel rail.
Consistent 255 LPH Flow for LS Engines up to 550 Horsepower
Rated to support engines up to 550 hp, the pump delivers a steady stream of fuel during wide open throttle events and steep gradients. A constant volume at varying engine speeds allows the engine control module to maintain precise air fuel ratio and spark timing without compensating for pressure loss. Drivers benefit from crisp throttle response from idle through redline, as well as smooth power delivery under load. This reliable flow rate is critical for both daily driven classics and track day excursions.
All Inclusive Kit for Streamlined Installation
This complete package arrives with every part needed for a full EFI conversion, including the 255 LPH pump, in tank module, sending unit, filler neck, vent filter, straps, gaskets and all mounting hardware. Each fitting is matched to the tank profile to eliminate fitment guesswork and extra trips to parts suppliers. Factory style connectors and clear access to mounting bosses ensure that hose routing and wiring can be completed quickly and accurately. By bundling everything in one box, the kit keeps your project moving and reduces the chance of installation errors.
