LS-Compatible EFI Fuel Tank Kit for 1973-1987 C10/C15 and K10/K15 Trucks
Swapping an LS engine into a 1973 through 1987 GM truck bed often stalls when the fuel system does not match the chassis contours and performance demands. This EFI fuel tank kit is engineered for eight foot C10 and K15 beds to lock into factory tabs without cutting or welding, delivering consistent flow with its 255 LPH Walbro pump module. Internal baffles guide fuel toward the pickup during cornering or heavy throttle, preventing starvation under load. With a rugged steel shell built in the USA, this assembly ensures sustained pressure for engines up to 550 horsepower.
Factory mounted design for effortless installation
From the moment setup begins, this EFI tank engages factory mounting tabs on GM pickup frames with eight-foot beds, preserving original contact points and chassis height. Builders avoid cutting, welding, or spacer fabrication by relying on a shell formed to align with OEM frame brackets. The included straps, brackets and hardware follow factory torque values to guarantee secure support under load. By eliminating custom metalwork, installers can concentrate on powertrain integration rather than body modifications. This direct-mount approach streamlines labor and maintains structural integrity.
Inside tank pump placement for temperature management
The Walbro pump module sits fully immersed in fuel, allowing the liquid to act as a heat sink that reduces operating temperature and extends service life. Delivering 255 liters per hour, it supplies steady flow to support engines rated up to 550 horsepower without pressure drop under rapid throttle shifts. Internal regulation maintains output consistency, preserving injector performance and throttle response at all times. By bathing the pump in its product, mechanical wear is minimized and thermal stress is controlled even under sustained high-load driving. This in-tank arrangement enhances reliability and performance simultaneously.
Fuel baffle network to ensure pickup coverage
An internal partition system creates multiple chambers that guide fuel toward the pickup outlet during cornering, acceleration or braking. These compartments limit slosh and keep the pump intake submerged to prevent momentary starvation under heavy demands. The rugged steel shell secures each baffle wall, preserving seal alignment and port dimensions under stress. Engineers calibrated partition lengths and opening sizes to balance stable delivery with rapid refill when levels run low. This baffle design delivers consistent fuel supply across a broad range of driving angles.
American built steel shell and comprehensive kit components
Manufactured in the United States from robust steel, the tank shell is treated with primer and sealant to resist corrosion from road conditions and modern ethanol blends. The kit includes a sending unit for accurate level readings, a filler neck, vent filter and durable gaskets for leak-free service. Tank straps and mounting hardware match factory style to ensure proper alignment with original frame points. Material choices prioritize chemical compatibility to guard against swelling or degradation over time. By providing every necessary component, this assembly offers a true plug-and-play solution that meets OEM standards.
