1973-1987 GM C10/C15 K10/K15 Truck EFI Fuel Tank Kit for LS Swap
Taking on an LS swap in a classic C10 or K15 pickup demands a fuel delivery system that fits exactly and performs without compromise. The 1973-1987 GM Truck EFI Fuel Tank Kit with a 255 LPH pump mounts to factory tabs on eight-foot beds in Chevy and GMC trucks, so no custom modifications are needed for installation. Its baffles channel fuel toward the pickup under cornering and hard acceleration to keep the pump fully submerged and eliminate starvation. By pairing a sturdy steel shell with a Walbro module rated for 550 horsepower, this kit supplies consistent pressure for EFI setups.
Precision Direct Fit Installation for 1973–1987 GM Trucks
From the outset this kit locks into existing mounting tabs on 1973 through 1987 Chevrolet and GMC pickup models with eight foot beds. Each tank is formed to match factory contact points so body height remains consistent and no fabrication is required. Builders save time by avoiding cutting or spacers while retaining original frame integrity. All straps, brackets and hardware are included to guide alignment and torque values. This approach keeps the installation process focused on powertrain integration rather than metalwork modifications.
255 LPH Pump Module for Consistent Fuel Delivery
The core of this system is a 255 liter per hour Walbro pump designed to support engines up to five hundred fifty horsepower. Located inside the tank, the module bathes in fuel to dissipate heat and reduce wear. Output remains stable during rapid throttle changes thanks to precise internal regulation. This arrangement avoids pressure drop under hard acceleration and tight turns. By delivering consistent flow the pump sharpens throttle response and maintains correct injector operation throughout a wide range of conditions.
Internal Baffle Design to Prevent Fuel Starvation
A network of internal partitions guides fuel toward the pickup outlet even when the truck is cornering or braking. These chambers limit slosh and ensure the pump intake remains covered at lean angles to prevent starvation under load. The steel shell encloses these compartments and resists deformation under stress, preserving seal integrity and pump position. Designers deep calibrated each baffle length and opening size to balance fuel flow stability with refill speed during low tank levels.
American Made Fuel Tank Assembly Ensuring Durability
Every component in this assembly is produced in the United States under strict quality standards for steel strength and corrosion protection. The shell is treated with primer and sealant to guard against environmental exposure and modern fuel blends. Included gaskets, filler neck and vent filter are chosen for chemical compatibility over extended service. This domestic build approach also provides fast access to replacement parts and technical support, giving builders confidence that long term reliability will match the demands of performance applications.
