LS Fuel Tank Kit for 1974-1977 Chevy Camaro and 1974-1978 Pontiac Firebird F-Body
Swapping an LS engine into a 1974 to 1977 Camaro or a 1974 to 1978 Firebird means you need a fuel tank ready to handle up to 550 horsepower without hesitation, and this EFI kit meets that requirement with a 255 LPH pump housed inside the reservoir. Housed within the tank, the Walbro unit cuts heat soak and trims operational noise, delivering rock steady pressure even during sustained acceleration. Installation attaches directly to F-Body mounts and uses OEM gaskets, straps and hardware for a clean fit that keeps the classic chassis lines intact. Every component ships in one crate ready for your swap, so you can move from tank removal to road test in a single afternoon.
In Tank Pump Design for Steady LS Fuel Delivery
The core of this kit is a 255 LPH Walbro pump installed inside the fuel reservoir, offering precise delivery to LS engines up to 550 hp. Locating the pump in the tank lowers fuel temperature by minimizing heat soak, which helps maintain optimal viscosity during hard acceleration or high ambient heat. Internal placement also cuts back on noise transmission into the cabin, creating a quieter driving environment compared with external pump setups. This arrangement ensures a stable volume of fuel is always available under sustained load, preventing momentary lean conditions that can harm engine performance. Drivers will notice sharper throttle response and consistent power output whether cruising on the highway or pushing hard on a back road. The balanced flow rate and reduced heat absorption make this in tank configuration a reliable solution for modern EFI conversions on classic chassis.
OEM Grade Fitment Preserving Classic F Body Lines
Every part in this kit is manufactured to match the exact dimensions of the 1974 to 1977 Camaro and 1974 to 1978 Firebird subframe mounts. The sending unit and pump module drop directly into the factory openings without any cutting or welding, providing a true plug and play result. OEM grade gaskets, straps and metal hardware create a precise seal and secure hold that mirrors the original design intent. By maintaining the stock tank profile and mounting geometry, the kit preserves the iconic F Body silhouette beneath the vehicle. The use of proven materials and tight tolerances ensures fitment will not sag or shift over years of driving. Installers gain confidence that the new tank system will blend seamlessly with surrounding components and maintain proper alignment for brake and exhaust clearance.
Comprehensive Kit Contents for a Streamlined Installation
This fuel tank package arrives complete with everything needed to swap out your original reservoir in a single afternoon. Included are tank straps, OEM inlet neck, vent filter assembly, gaskets and all required fasteners organized in a single crate. Clear step by step instructions walk the installer through removal of the old tank, insertion of the pump module and system bleed procedure. By grouping each component in one shipment, the kit eliminates extra ordering delays and reduces the risk of missing parts. The consistent parts inventory also helps professional shops maintain workflow efficiency and lowers overall labor costs. Whether performing a backyard project or a shop service, this all in one solution minimizes downtime and keeps your LS swap on schedule.
Manufactured in the USA to Ensure Quality and Durability
Each fuel tank and module in this kit is produced exclusively in the United States to meet strict manufacturing standards. US construction enables thorough quality control at every stage, from initial forming of the reservoir to final pump calibration. By using high grade metals and proven assembly methods, the kit offers long lasting performance even under rigorous driving conditions. Builders will appreciate the added peace of mind knowing each component is backed by domestic craftsmanship standards. Parts are tested for shape retention and leak integrity before leaving the factory, which helps prevent costly reinstallations. The result is a fuel delivery system engineered for reliable operation in classic Camaro and Firebird projects year after year.
