Frame-Mount 255 LPH Tank for 1963-66 Chevy Truck LS Swap

Built with an EFI ready system and a Walbro 255 LPH pump, the frame-mount tank secures under rear rails to deliver consistent flow for LS swaps up to 550 HP. Internal baffling prevents slosh during hard braking and cornering while maintaining accurate gauge readings, and an 18 gallon capacity extends driving range for long cruising sessions.

Frame Mount Fuel Tank for Chevy Truck LS Engine Swaps

When dropping an LS engine into a 1963-1966 Chevy truck this frame mount gas tank is designed to deliver the precise fuel supply your swap demands. This under bed installation slides neatly into the frame rails and houses a Walbro 255 LPH pump together with a 0 to 30 ohm sending unit for consistent delivery and accurate gauge readings. Internally baffled walls keep fuel steady during hard braking and cornering and the generous 18 gallon capacity extends your range between fill ups. Installation uses existing frame mounting points with minimal drilling to secure the tank behind the rear axle.

EFI Ready Fuel System Ensures Accurate Delivery

The tank's EFI ready layout pairs a precision 0 to 30 ohm sending unit with a Walbro 255 LPH pump to maintain consistent pressure under varying engine loads. This configuration supports engines up to 550 hp without starving injectors or causing erratic gauge readings. By accommodating factory electronics and requiring minimal calibration, it provides a drop-in solution for modern control systems. The result is smooth throttle response and reliable feedback at the dash.

Internally Baffled Construction for Steady Fuel Supply

Strategic baffling within the tank walls prevents fuel from shifting during hard braking or sharp turns. This internal partitioning ensures the pump inlet remains submerged at all times, eliminating the risk of momentary starvation that can interrupt engine performance. Maintaining a stable fuel column contributes to consistent combustion and protects pump longevity. Enthusiasts will notice a marked improvement in throttle feel under dynamic driving conditions.

Underframe Mounting with Minimal Modification

Designed to slide directly into the frame rails behind the rear axle, this unit makes use of existing mounting points with only minimal drilling needed for secure placement. Its precise 32 1/4 by 20 1/2 by 9 3/4 inch footprint optimizes cargo space while preserving ground clearance. The underframe position lowers the center of gravity for better handling balance. Installation remains straightforward for a technician familiar with classic Chevy truck platforms.

Generous 18 Gallon Capacity for Extended Range

An 18 gallon reservoir extends driving range by reducing the frequency of fuel stops on long trips or during track events. The included bed fill neck streamlines refueling, keeping flow rates high and spills low. Larger capacity also moderates fuel temperature by reducing pump run time, which can enhance component lifespan. For restorers and performance drivers alike, this capacity upgrade supports both daily use and spirited weekend drives.

Engineered for a precise fit and consistent performance in your LS swap.
