LS and LT 400 LPH EFI Fuel Tank Kit for 1978-1981 Camaro and 1979-1981 Firebird
When converting a 1978 to 1981 Camaro or a 1979 to 1981 Firebird to LS or LT power feeding the engine under load is critical and this kit solves that with a sealed tank and 400 LPH pump. It bolts to original frame rails without cutting or welding so chassis clearance and strength remain unchanged. The in tank Walbro unit rated for builds beyond 550 hp pairs with a sending unit, filler neck, straps and vent filter for complete fuel delivery. Clear instructions outline fuel line placement and pressure calibration to eliminate starvation during spirited runs and reduce installation time.
Precision Mounting for Factory Frame Rail Alignment
The fuel tank kit is shaped to match the original mounting points on 1978 to 1981 Camaro and 1979 to 1981 Firebird frames. By using the factory bolt holes, the design eliminates the need for cutting or welding and preserves chassis clearance and structural strength. This precise alignment ensures the tank sits flush beneath the body panels without interference from suspension components. Installers can move from test fitting to plumbing and wiring with minimal adjustments, saving time and reducing the risk of misalignment. The result is a secure installation that maintains the integrity of the F-Body platform.
400 LPH Walbro Pump Performance Under Load
Central to the kit is a 400 liters per hour Walbro pump engineered for builds beyond five hundred fifty horsepower. Its internal impeller and flow path are optimized to deliver consistent pressure during rapid throttle changes, preventing lean conditions and potential engine knock. This continuous fuel stream is critical for LS and LT engines running forced induction or high compression setups, especially under extended high load conditions. The pump placement inside the sealed tank also reduces the chance of vapor lock in hot environments, ensuring smooth operation from idle through full throttle. Enthusiasts will appreciate the confidence that comes with a reliable supply of high volume fuel.
Integrated Kit Components for Complete EFI Delivery
This comprehensive kit bundles a sending unit, filler neck, tank straps, vent filter, precision molded gaskets and mounting hardware to create a unified EFI fuel delivery system. The sending unit provides accurate level readings for onboard electronics while the vent filter ensures proper tank breathing to avoid fuel foaming under spirited driving. Robust stainless hardware and straps secure the assembly against dynamic loads and road vibration. Precision molded gaskets are matched to each component interface, reducing the risk of leaks and simplifying seal placement. By including all necessary parts, the kit eliminates the need for separate purchases and ensures all elements work together seamlessly.
Comprehensive Installation Guide for Faster Fitment
Clear, step by step instructions accompany the kit and include detailed diagrams for bracket placement and filler neck routing. Text notes highlight critical tasks such as fuel line positioning and pressure calibration to match engine management requirements. By following these directions, technicians can avoid common errors that lead to leaks or inadequate fuel flow under load. The combination of visual aids and written guidance cuts install time and boosts confidence, whether the project is a first time swap or a track weekend prep. This focused support ensures reliable fuel delivery and accelerates completion for any LS or LT conversion.
