Frame Mount Fuel Tank with 400 LPH Pump for LS Swapped 1963-1966 Chevy Trucks
Installing an LS engine in a 1963 to 1966 Chevy pickup demands a fuel system that can keep pace with spirited driving, and this frame mount gas tank ensures steady flow under heavy throttle and hard cornering. Internal baffles trap fuel around the pickup inlet, preventing slosh that would starve the Walbro pump during rapid maneuvers. Equipped with a 400 LPH pump housed inside the tank, a bed fill neck and a 0 to 30 ohm sending unit calibrated for original Chevy gauges, it integrates smoothly with modern EFI systems without the need for gauge modifications.
Baffle System Ensuring Stable Fuel Delivery
The internal baffles create separate chambers that hold fuel around the pickup inlet, preventing it from shifting during hard braking and sharp turns. By keeping the Walbro pump submerged, this system maintains a steady flow and reduces the chance of cavitation, which can cause momentary power loss. Racers and street drivers alike will notice more consistent throttle response under demanding conditions. This thoughtful design translates into uninterrupted performance when you need it most.
In-Tank Walbro 400 LPH Pump Efficiency
Positioned inside the tank, the Walbro 400 LPH unit draws cooling from the surrounding fuel, extending its service life and dampening operational noise. Delivering sufficient volume for engines up to 750 hp, it eliminates external feed lines and potential leak points, making installation both faster and cleaner. The compact pump placement also simplifies routing, reducing clutter under the pickup bed. Overall, this integrated approach boosts reliability for high-output LS setups.
Seamless Integration with Factory Gauges and Refilling
The included 0 to 30 ohm sending unit is calibrated for original Chevy pickup gauges, so there’s no need for custom wiring or calibration. Fuel level readings remain accurate and intuitive, preserving the classic dashboard look and function. A conveniently located bed fill neck mirrors factory ergonomics, making refueling quick and familiar. Together, these features let you monitor tank status without compromise.
Extended Range and Chassis Friendly Design
With an 18 gallon capacity, this frame mount tank cuts down on refueling stops during long drives or spirited outings. It fits neatly between the 1963-1966 Chevy truck rails, maintaining stock ride height and ground clearance for a balanced stance. Adding weight low and central enhances handling stability without altering suspension geometry. Enthusiasts will appreciate the blend of extended range and factory ride characteristics.
This frame mount tank ensures dependable fuel delivery and preserves your truck's factory fit and finish in an LS swap.
