LS and LT Fuel Tank Kit for 1973-1991 Chevy Blazer/Suburban and GMC Jimmy
For an LS or LT swap in a Chevy Blazer, Suburban or GMC Jimmy from 1973 through 1991 this fuel tank kit with its 400 LPH pump ensures the engine receives a constant fuel supply under spirited driving or heavy towing. It includes a precision 400 LPH pump, sending unit, vent filter and heavy duty straps that align with the stock tank footprint to prevent fuel starvation and speed installation. Durable steel construction and carefully sized internal ports resist vibration and ethanol fuel blends to deliver reliable performance mile after mile.
Optimal 400-LPH Pump for EFI Fuel Delivery
The core of this fuel tank kit is its 400 LPH high-flow pump, engineered to support LS and LT engines tuned beyond 550 hp without risk of starvation. Precise internal port sizing and premium seals maintain consistent fuel flow under hard acceleration, towing or steep inclines. By preventing cavitation, the pump ensures predictable throttle response during spirited driving or off-road excursions. This level of performance is critical for EFI conversions that demand steady pressure, even as fuel slosh or vehicle attitude change.
Robust Steel Tank Construction for Harsh Conditions
Manufactured from high-grade steel, the tank body resists corrosion and vibrational stress common in rough terrain or daily use. Expertly crafted weld seams eliminate potential leak paths, while material selection withstands modern ethanol blends without degradation. Heavy-duty straps and hardware hold the tank securely in place, preserving alignment and preventing fatigue under load. This rugged assembly is built to endure temperature cycling and the rigors of demanding environments mile after mile.
Integrated Kit Components Simplifying Installation
This complete assembly arrives with every element needed for a smooth EFI swap, from the in-tank module and sending unit to gaskets, tank straps, filler neck and vent filter. Each component is preconfigured to match the original tank outline, eliminating guesswork and trimming installation time. The vent filter and filler neck are calibrated for proper breathing under all driving conditions, reducing the chance of vapor lock. As a result, installers can focus on wiring and plumbing rather than hunting down hard-to-find parts.
Precision Engineered Fit for Model Years 1973 through 1991 Chevy Blazer and Suburban
Designed specifically for the classic Blazer, Suburban and GMC Jimmy chassis, this tank kit maintains factory ground clearance and frame geometry without modification. The sending unit pattern aligns with both stock and aftermarket gauge systems to deliver accurate fuel level readings. Local BRP Hot Rods fabrication ensures tight tolerances and consistent quality on every unit. By preserving original mounting locations, the design minimizes custom brackets or floor pan alterations during your LS or LT swap project.
