Designed for straightforward drop in fitment to Chevrolet and GMC pickups, this kit preserves classic lines while preparing your rig for demanding street or off-road use.
Robust Fuel Delivery with 400 LPH Walbro Pump
The 400 LPH Walbro pump at the heart of this kit is engineered to maintain stable pressure even when your LS or LT engine is pushed beyond 550 horsepower. By supplying a continuous, high capacity flow, it prevents lean spots during sudden throttle inputs or sustained high RPM runs. This level of delivery is especially critical for supercharged applications where fuel demand can spike instantly. The result is a smoother throttle response, more consistent power output and reduced stress on engine management systems.
Seamless Integration for LS and LT Engine Conversions
Designed specifically for 1973-1987 GM C/K trucks with eight-foot beds, this fuel tank kit aligns perfectly with the factory mounting points and fuel lines of both Chevrolet and GMC models. Its form-matched contours preserve the original underbody clearance and maintain the truck's classic profile. By eliminating the need for lengthy custom plumbing or frame modifications, it accelerates your conversion project and reduces the margin for installation error. This direct-fit approach lets installers focus on tuning and finishing rather than chasing fitment issues.
Comprehensive Installation Kit Simplifies Assembly
Every essential component is included to streamline the swap process: sending unit, tank straps, filler neck, vent filter, gaskets and all required hardware. The fuel pump module sits entirely inside the tank, lowering the risk of fuel line leaks and improving electrical connection reliability. Detailed engineering ensures each part works together, avoiding last-minute sourcing headaches. Novice mechanics and seasoned pros alike benefit from a kit that anticipates every step and keeps installation time to a minimum.
Durable Construction for Street and Off Road Use
This fuel tank assembly is built to endure the toughest driving conditions, whether you're cruising city streets or tackling uneven back roads. The sturdy tank body resists impact and resists corrosion for long service life. Reinforced mounting straps hold the assembly firmly in place under high-load scenarios and aggressive maneuvers.
