1974-1977 Camaro and 1974-1978 Firebird EFI Fuel Tank Kit for LS and LT Engines
When converting a 1974 to 1977 Camaro or a 1974 to 1978 Firebird to LS or LT power the factory tank can struggle to maintain stable EFI flow once output climbs beyond stock capacity. Equipped with a heavy gauge steel reservoir and a preassembled 400 LPH pump the kit ensures consistent delivery of fuel even under supercharger boost or high rpm runs. Installation taps original frame mounting points with all brackets and gaskets included so no cutting or custom adapters are required while internal baffles keep the pump inlet submerged during cornering or hard launches.
400 LPH Pump Performance for Boosted LS and LT Engines
The preassembled 400 LPH Walbro pump is sized to meet the demands of supercharged or over 550 hp LS and LT powerplants, ensuring a consistent flow rate even at elevated rpm. Its precision impeller design sustains stable rail pressure under full throttle acceleration, reducing the risk of lean spots that can cause detonation. By resisting vapor lock during heat soak or extended track sessions, the pump delivers reliable restarts and uninterrupted fuel delivery after spirited runs. This capacity gives tuners the confidence to push the engine to its limits without worrying about fuel starvation, especially under boost.
Tailored Chassis Fitment for Camaro and Firebird F Body Models
This EFI tank module is engineered to align with the original cell opening and frame mounting points on 1974–1977 Camaro and 1974–1978 Firebird F Body chassis. Factory fuel lines mate directly to the sending unit, preserving the stock routing and minimizing potential leak paths. Supplied straps, brackets and gaskets are laser cut to match mounting holes, allowing professional shops and home builders to install the assembly without fabricating adapters. A single plug connector streamlines wiring, ensuring accurate gauge readings from the moment power is applied and avoiding time-consuming rewiring tasks.
Simplified DIY and Shop Installation Workflow
Every component required for a complete retrofit arrives in one package, significantly reducing parts sourcing and fitment checks. The in-tank pump module, matched sending unit and filler neck integrate seamlessly with the existing frame rails, while the included tank straps, vent filter and hardware ensure a leak-free seal. Detailed instructions guide installers through removal of the original reservoir, module placement and post-installation leak inspection. By adhering to factory mounting points, this kit transforms a complex swap into a streamlined project that can be completed in a single session.
Heavy Gauge Steel Tank with Internal Baffles
Constructed from thick gauge steel, the replacement tank provides superior impact resistance against road debris and enhanced protection from corrosion over time. Strategic internal baffles control fuel movement during aggressive cornering, hard launches and sudden braking, keeping the pump inlet submerged to maintain uninterrupted flow. Weld joints are reinforced to withstand heat transmitted from underbody exhaust systems and to resist chassis vibration over years of service. The rugged design delivers stable fuel pressure on highway cruises as well as in high-demand performance environments.
