LS and LT Swap Fuel Tank Kit for 1973-1991 Chevy Blazer, Suburban and GMC Jimmy
Installing an LS or LT powerplant in a Chevy Blazer, Suburban or GMC Jimmy from model years 1973 through 1991 demands a reliable fuel system and this fuel tank kit with a 400 LPH pump ensures steady fuel flow tailored to EFI swaps. This complete assembly includes a precision 400 LPH pump, sending unit, vent filter and heavy duty straps that align with the stock tank footprint and reduce installation time. Built from materials chosen for resistance to performance stress and everyday road conditions it prevents fuel starvation during spirited runs and keeps the engine fed under varied driving scenarios.
Unwavering Fuel Delivery with 400-LPH Pump
The centerpiece of this kit is its 400 LPH pump, configured to maintain consistent fuel flow during aggressive driving or towing. By supporting engines tuned beyond 550 hp without risk of starvation, it ensures the LS or LT swap always receives the volume it demands. This steady pressure under acceleration and hard cornering translates directly into predictable throttle response and uninterrupted power delivery. Internal port sizing and quality seals work in tandem to prevent cavitation, keeping the engine running smoothly in off-road or track scenarios.
Precision Build Quality for Rugged Conditions
Constructed from high grade steel that resists corrosion and vibration, the tank body is designed to endure off-road abuse as well as daily use. Critical components like the sending unit and vent filter are chosen for long service life under repeated temperature cycles and exposure to modern ethanol blends. Expertly executed weld seams eliminate leak paths, reinforcing overall structural integrity. Heavy-duty mounting straps and hardware maintain exact alignment even when the vehicle carries heavy loads or encounters rough terrain, delivering confidence mile after mile.
Integrated Component Kit for Efficient Assembly
This all inclusive package comes with every piece needed for a complete EFI fuel system conversion, eliminating the hassle of sourcing parts separately. From the pump and in tank module to gaskets and mounting hardware, each item matches the stock tank footprint for a precision fit. The filler neck and vent filter are preconfigured to guarantee proper breathing and venting under all operating conditions. As a result, installers save hours of prep time and avoid fitment headaches, allowing focus on wiring and plumbing the new EFI components.
