EFI Fuel Tank Kit for LS and LT Swaps on 1974-1977 Camaro and 1974-1978 Firebird
Retrofitting an LS or LT engine into a 1974-1977 Camaro or 1974-1978 Firebird often reveals the stock tank cannot meet EFI flow requirements and fuel pressure stability when output climbs; this kit replaces it with a heavy gauge steel reservoir preassembled with a 400 LPH pump and precision sending unit. Installation uses supplied brackets, straps and gaskets at factory frame points so fuel lines plug in without custom adapters or modifications. Internal baffles limit fuel slosh during hard launches and cornering while the durable steel construction stands up to road debris impact and corrosion under spirited driving.
400 LPH Walbro Pump Capacity for Boosted LS and LT Engines
The included 400 LPH Walbro pump is engineered to sustain consistent fuel flow when a supercharger or other boost device raises output beyond 550 hp. Its precision impeller design maintains stable rail pressure under full-throttle acceleration, helping to eliminate lean spots that can lead to detonation. By resisting vapor lock during heat soak or lengthy track sessions, the pump ensures dependable restarts and uninterrupted performance after spirited runs. This capacity gives tuners the confidence to push LS and LT powerplants to their limits without fearing fuel starvation at high rpm.
Tailored Fitment for 1974–1977 Camaro and 1974–1978 Firebird F Body Chassis
This fuel tank assembly is preassembled to match the original cell opening and mounting points on classic Camaro and Firebird frames, so no adapters or modifications are required. Factory fuel lines mate directly to the sending unit and pump module, preserving original routing and minimizing potential leak paths. Supplied brackets, straps and gaskets align perfectly with factory frame points, making the swap straightforward for professional shops and home installers alike. A single plug connector further simplifies wiring and ensures accurate gauge readings from the moment power is applied.
Heavy Gauge Steel Construction with Internal Baffles for Fuel Stability
Fabricated from thick steel, the replacement tank offers superior impact resistance against road debris and enhanced protection against corrosion under spirited driving conditions. Strategic internal baffles limit fuel slosh during hard launches, aggressive cornering and sudden braking, keeping the pump inlet fully submerged at all times. Weld joints are reinforced to withstand heat rising from underbody exhaust systems and to resist chassis vibration over years of service. This rugged design delivers a stable fuel supply on highway cruises as well as in high-demand track environments.
Comprehensive EFI Retrofit Kit That Streamlines Installation
Every component needed for a hassle-free swap is included: a 400 LPH pump module, matched sending unit, filler neck, tank straps, vent filter, gaskets and all mounting hardware. Each piece is tailored for direct installation on F Body chassis without the need for custom adapters or extra parts sourcing. The all-in-one package reduces fitment checks and ensures installers can focus on tuning rather than tracking down hard-to-find pieces. With clear instructions covering removal of the old tank, module installation and leak inspection, the kit turns a complex retrofit into a single-session upgrade.
Built from heavy gauge steel for reliable performance you can trust. To complement your setup with a smaller capacity fuel pump kit at 255 LPH consider our 1974-1977 Camaro / 1974-1978 Firebird EFI Fuel Tank Kit - 255 LPH Pump.
