Simplify Your 1967-72 Chevy Truck LS Fuel Setup

For 1967 to 1972 Chevy trucks this frame mount gas tank with side fill uses a custom underside bracket for precise fit under the rails and convenient refueling access. Internally baffled chambers with an integrated Walbro 400 LPH pump and a 0 to 90 ohm sending unit ensure consistent fuel delivery during braking and cornering, support engines up to 750 HP and resist corrosion with galvanized steel construction and durable powder coat finish.

LS Engine Compatible Frame Mount Fuel Tank with Side Fill and 400 LPH Pump

When fitting an LS engine into a 1967 through 1972 Chevy or GMC pickup, this frame mount fuel tank with side fill and a Walbro 400 LPH pump solves both space constraints and fuel delivery reliability by mounting snugly under the rails. The integrated pump feeds up to 750 horsepower engines with consistent flow for spirited driving or heavy towing, while the internal baffle prevents fuel starvation during cornering and hard stops. It arrives ready with an 18 gallon capacity and a 0 to 90 ohm sending unit for seamless integration with factory dash gauges. Durable galvanized steel and a powder coated finish resist corrosion from road salt and moisture for lasting performance.

Custom Underside Fitment for LS Engine Swaps

This frame mount tank is engineered to slide precisely under the rails of a 1967 through 1972 Chevy or GMC pickup when performing an LS engine swap. Its contour-matched flange requires minimal drilling and aligns with factory mounting points, eliminating the need for major frame modification. By fitting snugly beneath the chassis, it preserves original ride height and body clearance while freeing up valuable space. Installers benefit from a quick, clean installation that resists movement under load and simplifies the swap process.

Advanced Baffle System to Prevent Fuel Starvation

Inside the tank, strategically placed baffle plates divide the volume into separate chambers to keep fuel at the pump inlet during every maneuver. Whether you are cornering hard or braking suddenly, these internal barriers dampen fluid inertia and maintain a consistent supply. This design is critical for spirited drives or heavy towing, as it prevents air pockets from reaching the pump and causing hiccups. By reducing pump cavitation, the baffled layout also extends service life and ensures reliable flow under all conditions.

Consistent Delivery with Walbro 400 LPH Pump and Zero to Ninety Ohm Sending Unit

At its core, a genuine Walbro 400 LPH fuel pump supplies up to 750 horsepower engines with steady pressure and volume. Mounted low in the tank, it uses gravity feed to reduce strain on internal brushes for longer service life. The integrated zero to ninety ohm sending unit interfaces directly with factory dash gauges, delivering accurate level readings without additional adapters. This pump-and-sensor combination supports modern EFI management while keeping wiring straightforward and maintenance tasks simple.

Galvanized Steel Construction with Protective Powder Coat

Built from durable galvanized steel, this tank withstands rust and corrosion in harsh road and off road environments. A silver powder coat layer adds a robust barrier against road salt, moisture and debris impact, blending seamlessly with original underbody components. Galvanization covers both interior and exterior surfaces, extending service life well beyond uncoated tanks. Even weld seams and mounting flanges receive full coating coverage, ensuring long-term protection and structural integrity.
