1973-1991 Chevy Blazer/Suburban/Jimmy LS and LT Fuel Tank Kit with 400 LPH Pump
For an LS or LT engine swap into a classic Chevy Blazer, Suburban or GMC Jimmy from 1973 to 1991, maintaining steady fuel flow under hard acceleration and towing is essential. This Blazer/Suburban Fuel Tank Kit with a 400 LPH pump tackles that challenge through a design that complements the stock tank footprint and feeds engines above 550 hp without risk of starvation. Constructed from high grade steel, the tank resists corrosion and vibration while precision ports and premium seals prevent cavitation under steep grades or spirited driving. The complete assembly preserves factory mounting points to simplify installation and integrates a sending unit that delivers accurate fuel level readings.
High Capacity 400 LPH Pump Ensuring Consistent Fuel Delivery
The heart of this kit is a 400 LPH Walbro pump engineered to support LS and LT swaps that exceed 550 horsepower. Precise port sizing and premium seal integrity maintain fuel pressure when under heavy load, whether towing a trailer or powering up steep grades. By eliminating cavitation risks, this pump sustains throttle response during acceleration bursts and off-road maneuvers. Its performance envelope covers spirited driving demands, ensuring the engine never goes hungry or dips below required pressure thresholds.
Robust Steel Tank Resisting Corrosion and Vibration Stress
Constructed from high grade steel, the fuel tank is designed to stand up to modern ethanol blends without degrading over time. Expertly welded seams remove weak points and provide leak free service despite rugged terrain or daily use. Integrated heavy duty straps and hardware anchor the unit firmly to the chassis to prevent fatigue from constant vibration. This combination of material strength and fabrication quality allows the assembly to endure temperature swings and mechanical shocks mile after mile.
All-Inclusive Kit Design Simplifying EFI Swap Tasks
This comprehensive fuel tank kit arrives ready for installation with every necessary component pre matched to the original mounting footprint. The in tank module and pump arrive assembled with the sending unit to deliver accurate level readings, while the filler neck and vent filter ensure proper breathing under all driving angles. Included gaskets and hardware eliminate the hunt for compatible parts, and the tank straps secure the assembly in factory locations. Installers save hours in preparation as each piece is configured for seamless integration into 1973–1991 Chevy Blazer, Suburban, or GMC Jimmy chassis.
Precision Fit for Classic Blazer, Suburban, and GMC Jimmy Models
Designed specifically for 1973 through 1991 Chevy Blazer, Suburban, and GMC Jimmy trucks, this kit preserves factory ground clearance and frame geometry with no cutting or welding required. The sending unit pattern aligns precisely with stock and many aftermarket gauge systems, ensuring reliable fuel level information from first start to shutdown. BRP Hot Rods production standards guarantee tight tolerances so that every tank drops in place without test fitting or alignment shims. The result is a clean, efficient swap that keeps your project on schedule and your fuel system operating flawlessly.
