1963-1966 Chevy Truck LS Engine Swap Frame-Mount Fuel Tank with 255 LPH Pump
For enthusiasts fitting an LS motor into a 1963 to 1966 Chevy truck this frame mount gas tank delivers the precise flow modern injection requires. Featuring internally baffled walls the tank maintains a steady fuel supply during hard braking and tight turns while the built in Walbro 255 LPH pump holds consistent pressure for engine builds up to 550 hp. Installation slides the 18 gallon reservoir into the rear frame rails behind the axle with minimal drilling and pairs a 0 to 30 ohm sending unit for accurate gauge readings.
Precision EFI Ready System for LS Swaps
This fuel tank features a Walbro 255 LPH pump paired with a 0 to 30 ohm sending unit to deliver the exact pressure modern LS injection requires. By matching factory gauge electronics, the setup provides accurate level readings without additional calibration. The high flow capacity supports engine builds up to 550 horsepower, ensuring injectors remain fed under heavy load. With plug‐and‐play wiring compatibility, drivers benefit from smooth throttle response and reliable dashboard feedback from day one.
Internal Baffling Ensuring Uninterrupted Supply
Strategically placed baffles within the tank walls prevent fuel from shifting during hard braking or tight cornering. This internal partitioning keeps the pump inlet submerged at all times, eliminating momentary starvation events that can cause misfires or hesitation. Consistent fuel delivery also reduces undue stress on the pump motor, extending its service life. During spirited driving or towing, this design maintains a stable fuel column for uninterrupted engine performance.
Under Frame Mount Design for Optimal Balance
Designed to slide into the rear frame rails, the tank secures with minimal drilling using existing mounting points for a snug fit. Its compact footprint preserves bed space and maintains ground clearance ideal for offroad or street use. Positioning the fuel mass low in the chassis lowers the center of gravity, improving handling and stability. Installation remains straightforward for any technician familiar with classic Chevy truck frames.
Extended Range with Generous Capacity
With an 18 gallon volume, this tank reduces the frequency of fuel stops on long highway drives or track outings. The larger reservoir also moderates fuel temperature by running the pump less often, which can enhance component longevity. A dedicated bed fill neck streamlines refueling and helps prevent spills during high-volume flow. For restorers and performance builders alike, the extra capacity translates into more time behind the wheel and less time at the pump.
Engineered for a precise fit and reliable performance in your LS swap.
