EFI Fuel Tank Kit for LS and LT Swaps on 1973-1987 C10/C15/K10/K15 Trucks
Placing an LS or LT powerplant into a classic C10 or C15 with an eight foot bed makes consistent fuel delivery the first hurdle under spirited acceleration and heavy towing. Housed within a precision welded steel shell tailored for 1973 to 1987 C10, C15, K10 and K15 trucks, the EFI fuel tank kit pairs directly with factory gauge wells and mounting points for a drop in install without cutting frame or bed floor. At its core is a 400 LPH pump capable of supporting supercharged and 550 horsepower setups without pressure loss during hard throttle. By maintaining stable line pressure and resisting cavitation in rough terrain, this module ensures injector performance remains steady from city streets to off road trails.
Precision Pump Performance for LS and LT Engines
The heart of this fuel system is a 400 LPH pump engineered to maintain stable pressure under severe throttle demands. It supports engines with forced induction or outputs beyond 550 horsepower without any drop in line pressure, ensuring injector consistency. An integrated inlet screen and filter minimize cavitation when cornering or tackling rough terrain, while the robust motor winding and reinforced casing deliver dependable flow through wide temperature ranges and extended use.
Direct Fit Installation in Classic GM Trucks
This kit is designed to install into the stock location of 1973 to 1987 C10, C15, K10 and K15 trucks with an eight foot bed, aligning precisely with factory gauge wells and mounting points. No frame modification or bed floor cutting is required, and the supplied tank straps, gaskets, filler neck and vent filter simplify setup. Clear instructions cover strap torque values and electrical routing to guarantee correct seal compression and reliable voltage delivery to the pump.
Robust Steel Tank Construction for Street and Trail Use
The fuel tank body is formed from heavy gauge steel with uniform wall thickness to resist impacts from road debris and preserve structural rigidity. Precision welding at all seams ensures leak free joints, while an internal baffle system controls fuel motion under hard braking or rapid direction changes. A corrosion resistant primer and protective finish guard against moisture, salt and mud to maintain appearance and function over time.
Integration of Critical Components Enhancing Reliability
Beyond the core pump module, this kit includes a calibrated sending unit, precision plumbing hardware and a vent filter matched to the tank design. The tailored filler neck and high quality gaskets prevent leaks at interface points, and the durable straps lock the assembly in place without vibration or movement. Each component works in concert to provide consistent fuel delivery and trouble free operation across varied driving conditions.
