1973-1987 C10/C15/K10/K15 GM Truck Fuel Tank Kit for LS and LT Engines
Swapping an LS or LT engine into a classic 1973 to 1987 GM C10, C15, K10 or K15 truck with a six foot bed demands a fuel system capable of sustaining modern horsepower peaks while fitting existing mounts. The 1973 to 1987 GM Truck EFI Fuel Tank Kit with a 400 LPH pump installs without cutting or welding and reuses the stock sending unit for reliable gauge readings. Crafted from corrosion resistant steel the tank resists ethanol blends and road salt while the pump module maintains stable pressure under throttle and load, ensuring consistent delivery that keeps engine response sharp through varied driving conditions. Installation hardware and detailed instructions are included to guide fast plug and play integration, reducing fabrication time and letting builders focus on engine tuning.
Steady Fuel Supply for Demanding Engine Swaps
The in-tank pump delivers a continuous 400 liters per hour flow rate, precisely matching the needs of supercharged or 550 plus horsepower LS and LT engines. By maintaining consistent volume under rapid throttle changes, it prevents lean conditions that can damage high output powerplants. Internal machining reduces pressure variation inside the module, keeping rail pressure within strict tolerances for both naturally aspirated and boosted applications. This steady delivery supports smooth combustion across all RPM ranges and safeguards performance when towing or racing. The result is a dependable supply of fuel that preserves engine response under extreme load.
Factory Mount Compatible for 1973 to 1987 GM Six Foot Bed Trucks
This fuel tank assembly aligns exactly with the stock mounting points on C10, C15, K10 and K15 models built between 1973 and 1987. It reuses the original sending unit boss so the factory gauge maintains accuracy without additional adapters. The design installs without the need for frame modifications, welding or custom brackets, allowing bolt-in placement with the included straps and hardware. Pre-routed wiring pigtails simplify electrical connections and eliminate guesswork. By preserving the factory geometry, this kit saves hours of workshop time and keeps the chassis in its intended configuration.
Corrosion Resistant Steel Shell for Harsh Conditions
Constructed from heavy gauge steel treated with a specialized rust inhibiting finish, the tank withstands ethanol blends, road salt and moisture without pitting or flaking. Each weld is inspected for a leak-free seal, and an internal vent filter prevents debris from entering the fuel system. This robust build tolerates daily vibration, temperature swings and impact common to work truck and off-road use. Formulated for long term durability, the corrosion resistant steel extends service life far beyond untreated alternatives. Quality control in a domestic manufacturing facility ensures every unit meets strict standards.
All in One Fuel Tank System to Streamline Installation
The complete kit includes the 400 LPH pump module, sending unit, filler neck, vent filter, tank straps, gaskets and all necessary hardware. By packaging fittings, fasteners and pigtail wiring in a single solution, it eliminates multiple trips to the parts store and cuts down on assembly errors. Detailed step-by-step instructions guide builders through tank removal, wiring connections and final fitment for fast plug-and-play integration. This all in one approach reduces fabrication time and shifts focus back to engine tuning and chassis setup. American sourced components and domestic assembly back the kit with reliable quality you can install with confidence.
