EFI Fuel Tank Kit for 1978-1981 Camaro and 1979-1981 Firebird LS and LT Engines
When swapping an LS or LT powertrain into a late seventies F-Body, consistent fuel delivery under aggressive throttle is non negotiable. This 1978 to 1981 Camaro / 1979 to 1981 Firebird EFI Fuel Tank Kit features a 400 LPH Walbro pump rated for builds above 550 horsepower inside a sealed tank that bolts to factory frame rails without welding, preserving chassis clearance and structural integrity. It also includes a sending unit, straps, filler neck and vent filter and clear instructions guide installers through fuel line routing and pressure adjustments to prevent starvation during spirited runs.
Precision Mounting to Preserve Frame Integrity
The EFI fuel tank kit is shaped to match the original mounting points on 1978-1981 Chevy Camaro and 1979-1981 Pontiac Firebird frames, aligning directly with factory frame rails and fastener holes. By eliminating cutting or welding, this design preserves chassis clearance and maintains the structural strength of the frame, while ensuring the tank sits flush under the body without contact with suspension parts. Technicians experience minimal trial fitting, moving straight to plumbing and wiring once the shell and mounting bracket are in place. This precise fit protects critical components and reduces installation time on LS and LT swap projects.
400 LPH Pump Ensuring Steady Supply for LS and LT Engines
Central to this kit is a 400 LPH Walbro pump selected for its ability to hold consistent pressure during rapid throttle changes and high load conditions. The specialized impeller and optimized flow path maintain a continuous stream of fuel, preventing lean conditions that can lead to engine knock or hesitation at wide open throttle. This level of delivery supports forced induction and high compression LS and LT power plants up to and beyond 550 horsepower, reducing the risk of vapor lock in hot operating environments. The result is unwavering fuel pressure from idle through full throttle.
Complete Fuel System Kit for Streamlined Assembly
Every element required for a full EFI fuel delivery solution is included in this single kit. The in tank pump module works with the sending unit, vent filter and filler neck to deliver smooth flow and proper tank breathing during spirited driving. Precision molded gaskets, robust tank straps and stainless steel hardware secure the unit under dynamic loads, while each component is engineered to fit the original body opening. Comprehensive instructions outline fuel line routing and regulator adjustment to minimize guesswork and ensure leak free operation.
Installation Guidance for Reliable Operation
Clear, concise instructions guide installers through each stage of the retrofit, from removal of the stock tank to electrical and fuel line connections. Visual diagrams illustrate correct bracket positioning and filler neck alignment, while text highlights critical steps for pressure calibration to match your engine management setup. The guide explains vent filter placement to prevent vapor buildup and offers troubleshooting tips for common issues. This support ensures a confident installation and consistent fuel delivery for street or track duty.
