Direct Fit Fuel Tank for 6.6L L8T Engine Applications
When adapting a 6.6L L8T powerplant to an LT series chassis, the factory fuel module often becomes the limiting factor under sustained high load. This direct fit fuel tank retains original contours and mounting locations yet increases flow and capacity to support engines rated up to 550 hp. Installation panels drop into existing frame rails without trimming or welding while the preinstalled 255 LPH Walbro pump ensures steady pressure during cornering and steep inclines. Treated straps molded gaskets and a corrosion resistant finish complete the package for reliable operation across varied climates.
Precision Contours for Classic Chevy Frame Integration
This replacement tank is custom engineered to match the original mounts of 1949 through 1952 Chevy chassis, preserving the vehicle's factory body lines and trunk clearance without any trimming or welding. Precision molded gaskets align perfectly with the frame rails and sheet metal contours, creating a reliable seal that prevents fuel leaks and road noise infiltration. The filler neck and strap geometry follow stock dimensions so that the tank sits flush under the trunk floor, maintaining the classic profile that restoration purists demand. By retaining the exact OEM weight distribution and mounting points, this unit avoids stress on body mounts and guarantees panel gaps remain true to the factory specification. Installers benefit from verified dimensions at every touchpoint, eliminating the need for trial fitting or shimming during installation.
Reliable Fuel Delivery with 255 LPH Walbro Pump
At the heart of this design is a genuine Walbro fuel pump rated at 255 liters per hour, capable of supporting engines up to 550 horsepower without risking fuel starvation. Placed inside the tank, the pump remains cooled by the surrounding fuel, which lowers operating temperature and extends component life. A built-in vent filter removes air pockets before they enter the lines, reducing the chance of vapor lock during hard acceleration, steep inclines or sustained high speed. This steady pressure delivery ensures a smooth throttle response and consistent power output across the rev range. All electrical connectors are sealed to prevent moisture ingress, preserving pump performance in humid and salty environments.
All Inclusive Kit Streamlining Installation Process
This complete package arrives with every component needed to install the system in one work session, including straps, filler neck, vent filter, gaskets, mounting hardware and the integrated fuel module with sending unit. All items are precision fabricated or molded to replicate factory contours for an effortless fit and seamless connection to the original wiring harness. Detailed, step by step instructions guide installers through mounting, sealing and electrical hookup, reducing trips to the parts store and cutting overall build time. The plug and play design of the pump module eliminates splicing or custom wiring, while the preassembled sending unit delivers accurate fuel level readings from day one. Even first time engine swap enthusiasts will find this approach significantly lowers the barrier to a successful installation.
Durable Construction and Corrosion Resistance for Long Service Life
Every surface and component is treated to withstand road vibration, temperature extremes and chemical exposure, ensuring the hardware and straps resist rust and fatigue over prolonged use. Gaskets are manufactured from high density materials that maintain sealing force through repeated thermal cycles, preventing leaks under pressure fluctuations. The tank shell is coated with a corrosion resistant finish that repels salt, moisture and road debris, warding off pitting and scale formation. Rigorous testing simulates years of use in harsh climates, validating that the assembly will deliver consistent fuel flow with minimal maintenance. Enthusiasts can rely on this robust construction to keep their high output engines fed reliably mile after mile.
