EFI Fuel Tank Kit with 400LPH Pump for LS/LT Swaps in 1973-1987 GM C10/C15/K10/K15 Trucks
Swapping an LS or LT engine into a classic 1973 to 1987 C/K six foot bed pickup demands a fuel system that can keep pace and this EFI fuel tank kit delivers just that. It installs without cutting or welding by aligning precisely to factory mounts and reusing the stock sending unit for reliable gauge readings. The in tank 400 LPH pump meets the demands of engines up to 550 horsepower under varied loads while maintaining steady pressure. Corrosion resistant steel construction and complete hardware kits streamline the swap process so builders spend less time fabricating and more time dialing in performance.
Consistent High Flow Delivery for LS and LT Engines
The in tank 400 LPH pump module is calibrated to support engines up to 550 horsepower, ensuring steady fuel volume under rapid acceleration and sustained load. Precision machining inside the pump housing minimizes pressure ripple, which helps maintain a stable rail pressure for both naturally aspirated and boosted LS or LT powerplants. This consistency guards against lean spikes during hard throttle openings and contributes to smooth combustion, preserving engine efficiency and response. By matching flow capacity to modern power demands, the system avoids fuel starvation even under towing or track conditions.
Exact Fit for 1973 to 1987 GM C and K Series Six Foot Beds
The tank design aligns perfectly with factory mounting points on C10, C15, K10 and K15 models from 1973 through 1987, eliminating any need for frame modification or additional brackets. It reuses the original sending unit boss, preserving accurate fuel gauge readings and maintaining the stock wiring harness. Because no cutting or welding is required, installers can drop the assembly into place and secure it with the provided straps and hardware. This tailored fit saves hours of fabrication work and ensures the chassis geometry remains factory correct.
Steel Tank Construction That Resists Corrosion
Crafted from robust steel and treated with a corrosion resistant coating, the fuel tank stands up to ethanol blends, road salt and moisture without pitting or flaking. Every weld point is inspected to guarantee a leak free seal, while the internal vent filter prevents debris or moisture from entering the fuel system. This durable construction tolerates vibration, impact and temperature swings that are common in daily driving or work truck applications. Manufactured in the USA under strict quality control standards, the tank delivers reliable service life.
All Inclusive Kit Simplifies Swap Installation
Every component needed for a complete swap is included, from the pump module and sending unit to tank straps, filler neck, vent filter and mounting hardware. Pre routed wiring pigtails on the pump module allow for a straightforward plug in connection, cutting down on electrical confusion and potential errors. Detailed instructions walk builders through each step, reducing trips to the parts store and shortening project time. By consolidating fittings, gaskets and fasteners in a single kit, the system streamlines installation so you can focus on tuning rather than fabrication.
Built for reliable performance and precise fit this kit ensures steady fuel delivery under varied conditions. For a smaller capacity fuel pump Kit at 255 LPH see our 1973-1987 GM Truck EFI Fuel Tank Kit - 255 LPH Pump - 6' bed.
