1973-1991 Chevy Blazer/Suburban and GMC Jimmy LS/LT Fuel Tank Kit with 400 LPH Pump
For LS or LT engine swap projects in 1973 through 1991 Chevy Blazer, Suburban or GMC Jimmy models, maintaining reliable fuel delivery under heavy load is essential. The 1973-1991 Blazer/Suburban Fuel Tank Kit with 400 LPH Pump addresses this by offering an EFI conversion tank kit equipped with a 400 LPH Walbro pump rated for supercharged or over 550 hp setups. This all inclusive assembly includes an in tank pump module, sending unit, tank straps, filler neck, vent filter, gaskets and installation hardware so builders receive a complete package. Manufactured locally to BRP Hot Rods quality standards, it supports LS and LT engines for direct replacement in Blazer, Suburban and Jimmy applications.
Consistent Fuel Delivery Under All Conditions
The 1973 to 1991 Blazer and Suburban fuel tank kit includes a 400 LPH pump that delivers a steady stream of fuel even when under heavy load or at high rpm. This flow rate supports supercharged powerplants and any setup targeting more than 550 hp without risk of a lean condition. By maintaining stable pressure across the entire fuel map, the pump prevents starvation during rapid throttle changes, hard cornering, or steep inclines. Such reliability is critical for applications that push the limits of fuel demand and engine calibration.
Precision Fitment for Classic Chevrolet Trucks
Specifically optimized for injection conversion in 1973 to 1991 Chevy Blazer and Suburban models, this kit installs directly into the factory cavity without major frame modifications. Its finely shaped contours match the stock tank position to ensure correct clearance and prevent contact with exhaust or brake lines. When used with MuscleRods mounts, the assembly aligns engine placement and chassis angles precisely. This partnership preserves the factory drive shaft geometry, minimizes vibration, and allows a straightforward installation path for custom drivetrains.
Durable Construction and Easy Installation
Constructed from precision engineered high grade materials, the tank resists corrosion and impact even in harsh environments. A user friendly layout places all service components within clear view, making pump removal or filter change fast and safe. Proudly manufactured locally to BRP Hot Rods quality standards, each unit benefits from consistent weld practice and tight tolerances. Owners gain a tank that stands up to extreme driving conditions and reduces maintenance time on the road or trail.
Optimized for Modern Engine Platforms
This kit accommodates both LS and LT engine series with its high volume pump and EFI ready design. Internal baffling and optimized pickup placement maintain consistent flow during aggressive maneuvers, preventing fuel slosh that can cause lean spots. Compatibility with popular GM small cubic inch engines streamlines the conversion process, reducing the need for custom plumbing. The result is a direct path to blend classic truck charm with modern powertrain performance.
