LS Swap Frame Mount Fuel Tank 1967-1972 Chevy Truck Bed Fill 400 LPH Pump
Fitting an LS engine into a late sixties Chevy truck often leaves no room for stock tanks so this 1967 through 1972 Chevy Truck Frame Mount Gas Tank with bed fill neck and 400 LPH feed pump tucks beneath the rear rails to maintain cargo area while ensuring steady EFI supply. Built with internal baffling it keeps the pump inlet submerged during hard cornering or braking to prevent fuel starvation. Installation is simplified by custom brackets that align with factory frame holes and preserve bed space for tools or gear. A 0 to 90 ohm sending unit provides factory gauge compatibility so readings remain accurate without aftermarket adapters.
Reliable Fuel Delivery with Walbro 400 LPH Pump
The integrated Walbro 400 LPH pump is engineered to support LS engines up to 750 horsepower by maintaining steady flow even under peak demand. Its precision-engineered internals minimize pressure drop and heat buildup, ensuring your fuel system stays cool during sustained wide-open throttle runs. By delivering a constant volume of fuel, the pump prevents hesitation or lean spikes that can compromise performance. This level of consistency is critical for both spirited street driving and track use.
Advanced Internal Baffling for Consistent Pickup
An intricate baffling network inside the tank keeps the pump inlet submerged under braking, acceleration, and cornering forces. Strategically placed partitions control fuel movement, eliminating air pockets that lead to momentary starvation and erratic ECU readings. This design preserves continuous flow so your EFI calibration remains stable in dynamic driving conditions. The result is a smooth throttle response from stoplight launches through sweeping turns.
Precision Fit Frame Mount Installation
Custom brackets align with existing frame holes, allowing the tank to secure beneath the rear rails behind the axle without modifying sheet metal. By following factory contours, the installation disperses weight evenly and lowers the center of gravity for improved handling. Under-frame placement also frees bed space for cargo or tools while protecting the tank from road debris. This straightforward approach reduces labor time and preserves the truck's original appearance.
Seamless Gauge Integration and Vintage Style Refueling
The supplied 0 to 90 ohm sending unit works directly with factory gauges, eliminating the need for adapters or complex rewiring. Combined with an 18-gallon capacity and a bed fill neck, the system extends driving range while mimicking classic fueler ergonomics. Refueling becomes a simple process through the bed fill aperture, preserving the stock look of your seventies Chevy truck. Together these features blend period-correct styling with modern EFI reliability.
Built for dependable EFI support and a smooth installation, this frame-mount tank ensures worry-free driving on your LS swap.
