1978-1981 F-Body Camaro/Firebird EFI Fuel Tank Kit with 255 LPH Pump for LS Swap
When swapping an LS engine into a 1978 to 1981 Camaro or a 1979 to 1981 Firebird maintaining a steady fuel feed under heavy load is vital for performance and reliability. The 255 LPH Walbro pump sits submerged in a precision formed steel tank that matches F Body frame rails to preserve ground clearance and align with original mounting locations. Internal placement helps keep the pump at a consistent temperature during cornering and prevents vapor lock at high RPM. Precision cut straps gaskets and a vent filter are included to streamline installation and ensure a proper seal for a worry free conversion.
Chassis Matching Tank Geometry
The fuel tank has been shaped to follow the frame rails of 1978 to 1981 Camaro and 1979 to 1981 Firebird models to maintain original ground clearance and support structure alignment. By matching the contour of the F Body chassis, the unit slips into the stock mounting points without trunk floor modification or frame rail trimming. This design preserves exhaust clearances and avoids interference with brake lines and rear suspension components. The close fit ensures stable positioning under acceleration and road load, while honoring the vehicle footprint established by factory dimensions. This attention to detail allows the modern EFI module to integrate seamlessly into the classic platform.
In Tank Pump Placement and Thermal Management
The 255 LPH fuel pump sits fully submerged inside the steel reservoir to maintain a uniform temperature and avoid vapor lock at elevated rpms and during hard cornering. Submersion in fuel prevents aeration and cavitation that can compromise flow when the vehicle experiences lateral forces or sustained high engine output. This placement also dampens noise and reduces heat soak from the engine bay, extending the service life of internal components. Rated to support up to 550 horsepower, the genuine Walbro unit delivers consistent delivery pressure under continuous load. The result is reliable operation for both spirited street driving and track day use.
EFI System Integration and Precise Fuel Control
Integrating the in tank module with electronic fuel injection systems provides a steady feed that supports tight injector pulse timing and clean throttle response. The consistent pressure in the delivery line allows the engine management unit to maintain optimal air to fuel ratios across all driving conditions, reducing lean spikes under acceleration. Improved fuel economy at part throttle and a stable idle profile benefit daily driving and performance tuning alike. This synergy between tank design and EFI control contributes to smoother transitions when the accelerator is applied or released. The package equips LS conversions with the fuel stability needed for accurate engine maps and diagnostics.
Complete Conversion Kit for Efficient Assembly
Every component needed for the swap is included, from the submerged pump and sending unit to tank straps, filler neck, vent filter, gaskets and mounting hardware. Precision cut straps and factory matched fittings line up directly with the original fuel and wiring attachments, reducing setup errors and fabrication work. A step by step guide walks through tank removal from the trunk pan, module installation and the plumbing and electrical connections required for a full EFI system. This eliminates trips to the parts store and keeps project timelines on track for both first time installers and seasoned technicians. The result is a streamlined conversion that builds confidence and ensures a reliable fuel supply from day one.
