63-66 Chevy Truck Frame Mount LS Side Fill Tank with 400LPH Pump

Optimized for 1963 to 1966 Chevy pickups, the frame-mount tank leverages a Walbro 400 LPH pump and internal baffles to guarantee steady fuel delivery under LS power demands. Easily refill via the side fill neck, enjoy accurate readings with the factory-compatible sending unit, and tap into an 18 gallon reserve for extended highway runs.

Frame Mount Fuel Tank with Side Fill and 400 LPH Pump for LS-Swapped Chevy Trucks

Tackling an LS engine conversion on a 1963 to 1966 Chevy pickup demands reliable fuel delivery and this frame mount fuel tank with a 400 LPH pump and side fill neck delivers consistent flow under hard acceleration. Its 18 gallon capacity and internal baffling prevent fuel starvation during cornering and heavy braking while supporting engines up to 750 horsepower. The integrated sending unit spans 0 to 30 ohm for direct connection to factory gauges and ensures accurate level readings without extra wiring. Finished to slip cleanly beneath the rear frame rails it installs with minimal modifications to the chassis and keeps underbody plumbing neat.

Efficient Internal Baffling for Uninterrupted Fuel Delivery

The tank's internal baffling is engineered to keep fuel around the pickup point when the truck brakes or takes a sharp corner, preventing starvation under dynamic conditions. By dividing the eighteen gallon volume into controlled chambers, the system reduces slosh and preserves steady pressure for the pump. This design is vital for LS engine swaps that require uninterrupted feed at high throttle openings. Consistent fuel delivery under load not only supports peak power output but also enhances safety by maintaining reliable engine response.

400 LPH Pump Designed for LS Engine Swaps up to 750 HP

At its core, the assembly features a Walbro 400 LPH pump that delivers the volume modern LS induction systems demand, even at power levels approaching seven hundred fifty horsepower. Installed directly in the tank, this pump enjoys continuous access to fuel, reducing the chance of cavitation and improving longevity. The in-tank mounting also simplifies plumbing, as the outlet lines remain close to the frame rails and follow a neat path under the body. With a flow capacity matched to high output engines, drivers can count on smooth acceleration and stable fuel pressure under prolonged throttle.

Side Fill Neck and Integrated Sending Unit Streamlining Installation

The side fill neck positions the inlet beside the frame rail for quick access, eliminating long filler hoses or bed adapters and preserving the classic pickup silhouette. Beneath the deck, the tank slides between the chassis rails with minimal trimming, keeping the underbody clean and reducing install time. A zero to thirty ohm sending unit mounts inside the tank, delivering accurate readings straight to factory gauges without extra modules or harnesses. The direct integration of pump, filler neck, and sensor means fewer components to route and a factory-style feel behind the wheel.

Engineered for a perfect fit and reliable fuel delivery in your LS swap.
