1969 Camaro/Firebird LS and LT EFI Fuel Tank Kit with 400 LPH Pump
When you fit an LS or LT engine into a 1969 Camaro or Firebird, the stock fuel system often cannot keep pace with modern EFI demands. This EFI fuel tank kit replaces the original unit with a precision-fit steel tank and integrates a 400 LPH Walbro pump directly to support up to 550+ horsepower conversions. It preserves the underbody contours of both models and arrives complete with a fuel sending unit, tank straps, quality gaskets and all necessary mounting hardware for a straightforward installation. Manufactured in the USA, the design maintains steady fuel flow under sustained load while simplifying plumbing and wiring.
Tailored Fitment for 1969 Camaro and Firebird Frames
This fuel tank is custom engineered to mirror the original underbody contours of the 1969 Chevrolet Camaro and Pontiac Firebird, allowing installation without modifying the frame or floor pan. By matching factory mounting points and pump recesses, it preserves chassis alignment and ride height while eliminating clearance issues. Installers benefit from a direct bolt-in solution that reduces the risk of leaks and misalignment commonly encountered with off-the-shelf replacements. The result is a restoration-grade installation that maintains the classic appearance and performance envelope of these iconic models.
In-Tank Module Ensuring Consistent Fuel Delivery
Positioning the pump inside the tank greatly improves cooling and minimizes cavitation when engine demand spikes, ensuring uninterrupted flow during hard acceleration or sustained high-rpm use. This internal arrangement also dampens noise and vibration compared to external setups, enhancing cabin comfort on spirited drives. With the module sitting at the lowest point in the reservoir, it draws fuel even under cornering forces or chassis roll. The integrated wiring and plumbing connections further reduce potential leak points, simplifying the assembly process.
400 LPH Walbro Pump Meets Demanding Power Requirements
At the heart of this kit, the 400 LPH Walbro pump supplies ample volume for supercharged engines or builds exceeding 550 horsepower, delivering the pressure headroom required during wide-open-throttle acceleration. Its high-speed motor maintains consistent output under sustained load, making it an ideal choice for both drag-strip and road course applications. Integrators can plan future power upgrades with confidence, knowing the fuel system has built-in capacity. This pump delivers reliable flow even in extreme driving conditions, preventing fuel starvation when you push the limits.
Complete Hardware Package for Streamlined Installation
The kit arrives ready to install with a fuel sending unit, tank straps, filler neck, vent filter, sealing gaskets and all necessary mounting hardware. Sourcing these components individually often adds hours to a swap project and introduces compatibility uncertainty. Every part is manufactured in the USA from materials tested for racing and street use, ensuring durability and corrosion resistance. With everything included, builders can focus on assembly rather than chasing missing pieces, shortening project timelines and avoiding costly delays.
