LS and LT 400 LPH EFI Fuel Tank Kit for 1969 Camaro and Firebird
Swapping a modern LS or LT engine into a 1969 Camaro or Firebird often exposes the stock fuel tank's limited flow and risk of vapor lock under hard driving. This EFI Fuel Tank Kit with a 400 LPH Walbro pump addresses that by delivering a continuous fuel stream for forced induction or builds over 550 HP. Each steel tank is formed to match the factory underbody geometry exactly and comes complete with straps, filler neck, vent filter and gaskets so installation requires no floor pan modifications and brake and exhaust lines remain clear. Because the pump stays fully submerged, it runs cooler and maintains suction during rapid acceleration or cornering even on ethanol blends.
Custom Fitment for 1969 Camaro and Firebird Chassis
Designed to integrate seamlessly with the classic 1969 Camaro and Firebird chassis, this steel tank is formed to follow every contour of the factory underbody. By reproducing original mounting points and recesses, it eliminates any need for cutting or modifying the floor pan. This precise fit maintains proper clearance for brake lines and exhaust plumbing while preserving factory ride height and frame strength. Builders can install the tank without custom alterations and trust that alignment is maintained under all driving conditions.
Submerged Pump Cooling and Pressure Stability
Inserting the high-capacity 400 LPH Walbro pump fully inside the tank ensures it remains submerged at all times, even during cornering or hard acceleration. Constant immersion in fuel keeps the pump temperature down and prevents vapor lock under heavy loads. When lateral forces shift fuel inside the reservoir, the outlet stays covered so flow remains uninterrupted. Sealed electrical connections guard against moisture and corrosion, delivering consistent pressure for engines with over 550 hp.
Robust Steel Construction with Corrosion Protection
Crafted from high grade steel, the replacement tank stands up to debris impacts and resists corrosion in wet or salt treated environments. Precision-formed walls and bends hold their shape under stress, preventing deformation that could lead to leaks or pump misalignment. Zinc plated straps and mounting hardware add a layer of rust protection and secure the assembly under dynamic loads. With all components made in the United States, this design meets rigorous quality standards for both road and competition use.
Comprehensive Kit Simplifying the Installation Workflow
This comprehensive kit includes every component needed for a smooth installation: the fuel pump module, sending unit, tank straps, filler neck, vent filter, gaskets and mounting hardware. Molded nitrile gaskets provide reliable sealing against ethanol blends and minimize chemical degradation over time. Each strap and bolt aligns with factory holes so installation becomes a straightforward bolt in procedure. By supplying all necessary parts, the kit removes the hassle of sourcing individual items and lets builders focus on final tuning and fitment.
