1973-1987 C10/C15/K10/K15 EFI Fuel Tank Kit with 400 LPH Pump for LS and LT Engines
For anyone fitting a 1973 to 1987 C10, C15, K10 or K15 truck with an LS or LT powerplant and an eight foot bed, fuel consistency becomes the first performance hurdle. This EFI fuel tank kit addresses that challenge with a 400 LPH pump housed in an in-tank module designed to drop into the stock location without frame or floor alterations. It maintains steady pressure under heavy throttle, supporting engines pushing past 550 horsepower while ensuring smooth throttle transitions. Built from steel with precision welds, it resists impact from road debris and rough terrain for reliable duty on street and trail.
Precision Fuel Delivery for Demanding LS and LT Engine Conversions
When upgrading to an LS or LT powerplant, maintaining steady fuel flow under all driving conditions is essential. This kit features a high-flow 400 LPH pump capable of supporting supercharged and 550+ horsepower setups without pressure drop under heavy throttle. By preserving stable line pressure at the rail, injector performance remains consistent, preventing lean spikes or hesitation during spirited acceleration or towing. An integrated inlet screen and precision filter reduce cavitation risk when cornering or traversing rough terrain. The pump's robust motor and reinforced housing deliver reliable output through wide temperature swings and extended track sessions.
Integrated In Tank Pump Module Streamlining Installation Process
This fuel system employs an all-included in tank pump module that arrives ready to install in the stock location of 1973 to 1987 GM C10, C15, K10 and K15 trucks with eight foot beds. No frame or bed floor cutting is required, as the module aligns perfectly with factory gauge wells and mounting points. Included tank straps, gaskets, filler neck, sending unit and vent filter eliminate parts sourcing and simplify setup. Step-by-step instructions detail strap torque values and electrical connector routing, ensuring correct seal compression and reliable voltage delivery to the pump. The direct fit design reduces labor time and error potential, even for technicians new to classic truck systems.
Robust Steel Structure Engineered for Dynamic Street and Trail Conditions
Constructed from heavy gauge steel with uniform wall thickness, the tank body resists impacts from road debris and offers superior rigidity compared to stamped or polymer alternatives. Precision MIG welding at critical seams produces leak free joints, while a corrosion resistant primer and epoxy finish protect against salt, mud and moisture. An internal baffle system controls fuel slosh without reducing usable capacity, preserving consistent pickup under hard braking or rapid directional changes. This durable design maintains stock handling characteristics and minimizes maintenance, making it ideal for daily driving, off road adventures or towing heavy loads.
To fit applications where a smaller capacity fuel pump Kit at 255 LPH is desired, consider our 1973-1987 GM Truck EFI Fuel Tank Kit - 255 LPH Pump - 8' bed to ensure consistent performance across varied conditions.
