In addition to the in tank fuel module, the kit includes a sending unit, tank straps, vent filter, gaskets and all necessary hardware for a straightforward installation. Whether you aim for a comfortable daily driver or a build that supports up to 550 horsepower, this solution maintains your vintage styling while providing reliable EFI operation.
Optimized Fuel Pump Performance
The 255 LPH Walbro pump at the heart of this kit is calibrated for LS engine fuel demands up to 550 horsepower. Precision fluid dynamics within the pump ensure stable pressure under load, eliminating lean conditions during hard acceleration or sustained high rpm driving. Robust internal components resist wear and maintain consistent output even under extended use, so engine tuning remains predictable and safe.
Factory Location Fitment for Vintage B Body
Designed specifically for Impala, Bel Air, Biscayne, and Del Ray models from the late 1950s, the tank contours match the original underbody layout. This preserves the factory floor pan and maintains the car's ride characteristics without chassis modification. Included straps and hardware replicate the stock mounting method, ensuring the tank sits securely while retaining proper ground clearance and alignment.
Complete Installation Package
All necessary parts-from the sending unit and filler neck to vent filter and gaskets-are included in one box, cutting down prep time and part sourcing. Consolidating pump, module, and filter within the tank reduces external plumbing joints and potential leak points. Installers gain a clear, straightforward process that minimizes surprises and speeds up the swap procedure.
Modern EFI Integration with Timeless Appeal
Introducing electronic fuel injection into a classic chassis demands balance between technology and style. This tank kit conceals the in tank module to preserve the vehicle's original appearance while delivering precise fuel metering for smoother throttle response and steadier idle quality. The result is improved drivability and efficiency without altering the car's iconic silhouette.
