Optimized Fuel Supply With 255 LPH Walbro Pump
The heart of this system is a high-performance 255 LPH Walbro pump, chosen for its proven capacity to supply steady fuel flow under demanding conditions. Calibrated for LS engine architectures, it maintains consistent pressure at engine outputs up to 550 horsepower, preventing lean spots during rapid throttle changes. By delivering a constant high-volume stream, the pump supports smooth acceleration and stable cruising, even when pushing the Corvette on spirited highway runs. Its robust design also offers extended service life in corrosive fuel environments.
Comprehensive Fuel System Kit Components
More than just a pump, this kit includes all critical hardware for a turnkey upgrade: an integrated pump module, precision sending unit, filler neck, vent filter, tank straps, gaskets, and mounting bolts. The sending unit provides accurate fuel level feedback to the dash, while the vent filter controls vapor release and prevents contamination. High-quality gaskets and straps secure the assembly and guard against leaks, and the included filler neck ensures proper alignment of the fuel cap. Together, these parts form a unified system that protects tank integrity and promotes reliable operation.
Streamlined Installation for Enthusiasts and Beginners
Designed with installer efficiency in mind, the kit comes with clearly labeled components and hardware arranged for intuitive assembly. No welding or cutting is required-every bracket and seal lines up with factory openings and fasteners. Step-by-step instructions guide you through removal of the old tank module, placement of the new assembly, and final leak checks. Whether you're a seasoned mechanic or tackling your first swap, this straightforward process minimizes shop time so you can get back on the road faster.
