Frame-Mount LS Fuel Tank for 1967-1972 Chevy Truck
When fitting an LS engine into a 1967 to 1972 Chevy truck frame, maintaining proper fuel delivery under the rails is a common challenge. Offering both 18 gallon capacity and a bed fill neck, the 1967-1972 Chevy Truck Frame Mount Gas Tank - Bed Fill - 400 LPH Pump installs behind the rear axle to preserve cargo space while feeding your EFI system through a reliable 400 LPH pump. It relies on internal baffling to prevent fuel starvation during sharp turns and hard braking and comes with a 0 to 90 ohm sending unit compatible with factory gauges. With its precise fit and durable construction this tank eliminates the need for in bed modifications and keeps your swapped LS mill running smoothly.
400 LPH Walbro Pump Delivers Steady Flow for Up to 750 Horsepower
The proprietary Walbro 400 LPH pump at the core of this tank is engineered to support engines producing up to 750 horsepower, ensuring a consistent fuel supply under all driving conditions. Its high flow rate minimizes pressure drop, so even during sustained wide-open throttle, your LS swap will never starve for fuel. Built with precision tolerances and durable internals, the pump provides smooth delivery at highway speeds and spirited acceleration alike. This level of performance avoids the surging or hesitation that can plague lesser systems when demand spikes.
Internal Baffles Prevent Fuel Starvation in Dynamic Conditions
An intricate baffling network inside the tank maintains fuel pickup even when cornering hard or braking suddenly. These strategically placed partitions avoid sloshing and keep the pump inlet submerged, eliminating the air pockets that lead to momentary fuel loss. By stabilizing the fuel under lateral and longitudinal forces, the system preserves continuous flow and helps your EFI calibration remain accurate. The result is dependable throttle response whether you're navigating winding back roads or hauling loads downhill.
Frame Mounting Behind Rear Axle Preserves Cargo Area
Custom brackets secure the tank beneath the rear rails behind the axle, freeing the bed for gear without splicing or modifying sheet metal. The precise fitment follows the factory frame contours, distributing weight evenly and reducing stress on chassis rails. This under-frame location also lowers the center of gravity, improving handling while protecting the tank from road debris. Installation requires minimal drilling, and the included hardware aligns perfectly with existing mounting points for a straightforward upgrade.
EFI Sending Unit and 18-Gallon Capacity Simplify Use
A calibrated 0 to 90 ohm sending unit works seamlessly with your factory gauge cluster, offering reliable readings without aftermarket adapters. Combined with an 18-gallon tank volume, you gain extended range between fill-ups while maintaining a period-correct look and bed-fill access. The bed-neck design replicates the classic service style yet routes cleanly through the chassis for easy refueling. Together these features deliver both form and function for daily driving or long hauls.
This frame mount tank delivers consistent performance and peace of mind for your LS swap.
