LS and LT EFI Fuel Tank Kit for 1969 Chevy Camaro and Pontiac Firebird
Installing an LS or LT powerplant in a 1969 Camaro or Firebird quickly exposes the limits of the original fuel tank. This EFI fuel tank kit replaces the factory unit with a precision-fit steel tank that retains the factory mounting points and underbody shape for a clean installation. At its heart the assembly includes a 400 LPH Walbro pump capable of supporting supercharged or 550+ horsepower engine builds while maintaining steady flow during spirited driving. Comprehensive hardware is included from the sending unit to mounting straps so builders can complete the swap without sourcing extra parts and focus on the engine instead of chasing missing components.
Custom Fitment That Preserves Chassis Integrity
This fuel tank replicates the original underbody contours of 1969 Camaro and Firebird frames, allowing a direct bolt-in swap without altering the floor pan or crossmember. By aligning with factory mounting points and recesses, it maintains precise chassis alignment and ride height, reducing the risk of leaks and frame stress commonly seen with universal replacements. The use of high-grade steel ensures structural rigidity and resistance to road hazards, while preserving clearance for brake lines and exhaust components. This approach delivers a restoration-quality installation that respects the classic aesthetics and performance envelope of these iconic models.
In Tank Pump Module Optimizes Fuel Delivery Under Demand
Positioning the 400 LPH pump inside the reservoir offers immediate cooling from surrounding fuel, significantly reducing the chance of vapor lock when engine output spikes. This arrangement also dampens operational noise and vibration compared to external setups, improving cabin comfort during spirited driving sessions. Because the pump sits at the tank's lowest point, it maintains suction even under cornering forces or chassis roll. Integrated wiring and sealed connectors further minimize leak points and simplify routing, making the assembly both reliable and serviceable.
400 LPH Walbro Pump Suits Supercharged and 550+ Horsepower Builds
The included Walbro unit delivers flow rates that support forced-induction systems and engines exceeding 550 horsepower, providing ample pressure headroom to ensure consistent delivery during wide-open-throttle acceleration. Its precision engineering maintains steady output under sustained load, making it an ideal choice for dragstrip launches and road-course sessions. Builders gain the confidence to pursue future power upgrades without swapping fuels system components. Strong performance in extreme conditions means you avoid fuel starvation at peak demands, preserving engine health and performance.
Comprehensive Hardware Package Streamlines Installation
Rather than sourcing parts separately, this kit includes a calibrated sending unit, steel tank straps, filler neck, vent filter, molded gaskets and all mounting hardware, tested for fit and function. Strap components are zinc-plated for corrosion resistance, while gaskets use nitrile rubber to seal against leaks and withstand ethanol blends. Every item is manufactured in the USA, meeting rigorous standards for track and street use. With this complete set, builders spend less time chasing missing pieces and more time on precise assembly and tuning.
