1969 Chevy Camaro and Pontiac Firebird EFI Fuel Tank Kit for LS Swap
Anyone installing an LS engine into a 1969 Camaro or Pontiac Firebird faces the challenge of keeping rail pressure steady under hard cornering and acceleration and the EFI Fuel Tank Kit addresses that requirement. Molded to match original underbody contours this replacement tank houses a 255 LPH Walbro pump in fuel immersion to reduce heat soak and noise. Internal baffling stops fuel slosh during lateral forces and sustains flow for setups up to 550 horsepower. All mounting straps, wiring harness, sending unit and seals are supplied so the tank installs with factory mounting points and avoids custom body work.
Engineered to Fit 1969 Camaro and Firebird Chassis
Each fuel tank is molded to follow the 1969 Camaro and Firebird floor pan contours with millimeter precision, ensuring it seats firmly without modifications. It aligns with the factory mounting points and uses the original straps, preserving ground clearance and appearance. The filler neck and vent filter connect directly to existing openings, eliminating the need for trimming or custom fabrication. By matching the stock underbody geometry the kit integrates seamlessly, supporting straightforward mounting and reliable sealing. This engineered fit streamlines installation while maintaining the vehicle's structural integrity.
In Tank Pump Immersion for Cooler Quiet Operation
Placing the Walbro pump entirely inside the fuel cavity keeps it in constant contact with liquid, which absorbs heat and dampens vibration. This immersion arrangement reduces noise output compared to external pump setups and prevents heat soak that can degrade pump longevity under heavy use. Continuous circulation of fuel around the motor also helps avoid vapor lock and maintains stable delivery during hard acceleration. This thermal control contributes to consistent rail pressure for engines up to 550 horsepower while extending service intervals.
Integrated Baffling Prevents Fuel Slosh under G Forces
Strategically positioned baffles within the tank compartment channel fuel toward the pump inlet during sudden directional changes or cornering maneuvers. This internal barrier system stops pockets of air from forming around the pickup, protecting against drops in rail pressure that can cause hesitation or misfire. The design also incorporates a fine mesh filter element to trap debris and limit contamination of the injection components. Together these features ensure uninterrupted flow even under track conditions or spirited driving.
Complete Hardware Package for Streamlined EFI Upgrade
Rather than sourcing parts separately, this kit includes the pump module, sending unit, straps, gaskets, filler neck and vent filter, as well as all required mounting hardware and wiring. Each component has been selected to mate directly with the tank body and vehicle openings, cutting installation time and reducing the risk of leaks. The wiring harness integrates seamlessly with existing connectors to power the pump and send accurate fuel level data. Detailed instructions walk installers through each step, so professionals and home builders can achieve consistent results without guesswork.
