Replacement Fuel Tank for 6.6L L8T LT Series Vehicles
Integrating a 6.6L L8T powerplant into an LT series chassis often reveals the shortcomings of the stock fuel module, and this replacement unit addresses that weak point with capacity and flow built to handle engines up to 550 hp. Fully compatible with factory mounting points, the tank drops in without trimming or welding, and its stock capacity design preserves original contours and trunk clearance. A high capacity 255 LPH Walbro pump is preinstalled, supplying consistent pressure under heavy acceleration or sustained high load. Installation hardware and gaskets are included and precision molded to match frame contours for a reliable seal. Even after miles of spirited driving the treated straps and corrosion resistant finish ensure that fuel delivery remains steady and maintenance intervals stay minimal.
Precision Fitment for 1949 to 1952 Chevy Frames
This fuel tank is engineered to drop directly into the original mounting location on early Chevy chassis without the need for cutting or welding. Precision molded gaskets align perfectly with factory contours to maintain trunk clearance and preserve the classic profile of your vehicle. The filler neck and strap geometry follow stock dimensions, keeping the weight distribution and aesthetic balance as intended by the factory. Every measurement has been validated to ensure seamless integration with body mounts and frame rails, delivering a restoration result that looks and feels authentic.
Consistent Flow with 255 LPH Fuel Pump
At the core of this EFI solution is a Walbro pump rated at 255 liters per hour, designed to support engines producing up to 550 hp without risk of fuel starvation. This capacity maintains steady pressure during hard acceleration, steep inclines or sustained high loads, preventing lean spots at high RPM. An external vent filter removes air from the lines, enhancing throttle response and ensuring a smooth power delivery curve. By providing reliable flow under demanding conditions, this pump helps high-output engines perform at their peak.
DIY-friendly Kit Assembly
All necessary parts arrive in one complete package, reducing trips to the parts store and cutting overall build time. The in-tank fuel module comes preassembled with the sending unit and mates directly with factory wiring harnesses for plug-and-play operation. Included tank straps, filler neck, vent filter, gaskets and hardware are precision molded or laser cut to match vehicle contours, and the step-by-step instructions guide installers through each stage. Even those tackling an engine swap for the first time will appreciate how this kit removes guesswork and streamlines the process.
Premium Construction for Weather and Vibration Resistance
Every component undergoes rigorous corrosion and endurance testing to ensure reliability across diverse climates and harsh driving scenarios. The fuel pump assembly resists wear and maintains optimal operating temperature, reducing the need for frequent service. Protective finishes on straps, gaskets and hardware guard against rust and scale, even in humid or salted-road environments. This focus on robust construction gives enthusiasts confidence that their fuel system will deliver consistent performance mile after mile.
