LS and LT Fuel Tank Kit for 1973-1987 C10/C15/K10/K15 GM Trucks
The 1973-1987 GM Truck EFI Fuel Tank Kit featuring a 400 LPH pump addresses the exact needs of LS and LT engine swaps in C10, C15, K10 and K15 models with six foot beds. This complete system includes the fuel pump module, sending unit, filler neck, vent filter, gaskets, straps and all mounting hardware required for direct fit installation without cutting or welding. Crafted from corrosion resistant steel and engineered to match factory mounting points, it reuses the stock sender for accurate gauge readings while delivering the 400 liter per hour flow demanded by supercharged or 550 plus horsepower applications. Plug and play compatibility with LS and LT platforms reduces fabrication time and the American made construction ensures reliable performance in classic GM trucks.
Overview and Fitment
The 1973 to 1987 GM Truck EFI Fuel Tank Kit with a 400 LPH pump is engineered to match the specific chassis of Chevrolet and GMC pickups with a six foot bed. This assembly is a direct fit for original mounting points and tank recesses on these model years, eliminating the need for custom sheet metal work. Crafted in the USA by MuscleRods, it ensures precise engine placement and proper drivetrain angles when used with MuscleRods mounts. By retaining factory style fill neck position and tank height, it maintains stock fuel door alignment and avoids interference with the frame rails.
Pump Capacity and Engine Response
At the heart of the system is a 400 liter per hour pump designed to support supercharged engines and applications exceeding 550 horsepower. Its capacity meets the demands of LS and LT platforms without risk of starvation under heavy load. Internal flow passages are tailored to reduce turbulence and ensure a constant supply, while the return line path balances pressure at high rpm. This configuration sharpens throttle response, reduces startup lag, and stabilizes fuel pressure during rapid acceleration and cornering, protecting high compression and boosted powerplants.
Design, Durability and Quality
The fuel tank combines a corrosion resistant polymer body with reinforced steel straps to withstand impacts and harsh environments. Precision welded seams resist fatigue and prevent leaks, while internal baffles minimize fuel movement during dynamic driving. Every unit undergoes a multi point pressure and flow test, ensuring consistent performance in extreme conditions. Engineered for longevity, this kit resists chemical attack from modern fuel blends and maintains its integrity under repeated thermal cycling.
Installation and Support
This comprehensive kit includes fuel lines, wiring harness adapters and mounting hardware that attach to the factory brackets without modification. Detailed instructions guide the installer through each step, from tank positioning to pump wiring. For custom chassis or aftermarket frame rails, the kit integrates with additional brackets offered by MuscleRods. Technical support is available from trained specialists to address fitment questions and deliver a smooth upgrade experience, ensuring the fuel system performs reliably from first fire to race day.
