1973-1991 Chevy Blazer/Suburban/GMC Jimmy LS Fuel Tank Kit with 255 LPH Pump
When retrofitting a Chevrolet Blazer, Suburban or GMC Jimmy from 1973 to 1991 with an LS powerplant, the 1973 to 1991 Blazer/Suburban Fuel Tank Kit - 255 LPH Pump directly addresses the common shortfall of original tanks under sustained load. This kit installs a 255 LPH Walbro pump inside the steel reservoir and supports up to 550 hp with a sending unit, vent filter, filler neck, straps plus all gaskets and hardware included. Its preassembled module ensures an efficient EFI conversion while avoiding cutting or welding. For builds above 550 hp, choose the 340 LPH pump kit.
Purpose Built Fuel Delivery for LS Swaps
The 1973 through 1991 Blazer/Suburban Fuel Tank Kit with a high-flow 255 LPH Walbro pump delivers the precise fuel volume required to support up to 550 horsepower. This pump selection directly addresses the higher demand of electronic fuel injection on LS engines by maintaining stable pressure during rapid throttle changes and extended heavy loads. By matching pump capacity to potential output, the system prevents fuel starvation under full throttle, preserving consistent power delivery on pavement or trail.
Seamless Integration in Blazer and Suburban Frames
Fully tailored components have been engineered specifically for Chevrolet Blazer and Suburban models from 1973 through 1991. The tank shape and mounting hardware follow the factory chassis contours for a bolt-in fit, eliminating complex modifications. Integration with MuscleRods mounts ensures correct engine placement and drivetrain angles, maintaining proper alignment of the torque converter, driveshaft and rear axle. This precise positioning reduces stress on universal joints and offers confidence in long-term drivetrain durability.
Durable Construction and EFI Readiness
The low-profile steel tank features a corrosion-resistant coating and is secured with reinforced straps and hardware designed to withstand vibration and road hazards. The pump assembly sits inside a sealed sock filter that blocks contaminants, extending service intervals. Enabling EFI conversion transforms the original carbureted setup into a modern injection system that delivers consistent fuel atomization and throttle response. This upgrade enhances drivability, cold-start reliability and emissions performance without altering the body or sheetmetal.
Comprehensive Kit for Smooth Installation
Every fitting, hose, clamp and mounting bolt arrives in one complete package, backed by detailed instructions that guide the installer through tank removal, pump swap and connection to the existing fuel rail. By grouping all necessary parts, the kit minimizes downtime and avoids extra trips to the parts store. Whether building a daily driver or an off-road rig, this fuel tank solution offers professional fitment, reliable operation and the performance expected from a factory-grade system.
Built to match factory contours and featuring a high-flow Walbro pump rated for 550 hp, this fuel tank kit brings reliable support to LS engine swaps. For applications above 550 hp, choose the 340 LPH pump kit.
