This direct installation design mounts to the original F Body frame rails without cutting or welding, preserving chassis integrity while providing a 400 liter per hour Walbro pump module for builds above 550 hp. Complete with sending unit, filler neck, tank straps, vent filter, gaskets and installation hardware, and made in USA, it ensures consistent fuel flow for forced induction or high output naturally aspirated applications. Clear instructions guide precise fuel line placement and pressure calibration for faster setup and reliable operation.
Overview
The 1978-1981 Camaro / 1979-1981 Firebird EFI Fuel Tank Kit combines a precision molded tank and an integrated 400 LPH Walbro pump to modernize fuel delivery for LS and LT engine installations. Designed specifically for these classic GM models, it replaces the original tank with a unit sized to fit the factory mounting points and fuel lines. This kit addresses the demands of boosted and high output powerplants, ensuring the tank capacity and inlet geometry meet rigorous performance standards. Each component arrives fully assembled and pressure tested to maintain safety and reliability.
Performance and Reliability
The included 400 LPH Walbro pump is optimized for supercharged systems or engines producing over 550 hp, offering high-flow delivery to eliminate fuel starvation during hard launches and sustained high rpm operation. By maintaining consistent pressure under extreme load, the kit prevents lean conditions that can lead to engine damage. The internal pickup design keeps the pump submerged even during cornering or rapid weight shifts, ensuring uninterrupted flow. This level of performance makes it ideal for drag racing, road course use, and street machines that demand a stable fuel supply.
Installation and Engine Integration
With a precision fit design, this kit bolts into place using the factory frame rails and original sender mount locations, allowing direct installation without custom brackets. It is engineered from the outset to accommodate LS and LT engine retrofits, simplifying conversion projects in these Camaro and Firebird platforms. Clear, easy to follow instructions reduce installation time and eliminate common alignment errors. When combined with MuscleRods mounts, the system maintains exact engine placement and drivetrain angles, preserving drive shaft alignment and transmission input shaft centerline for reliable operation and reduced vibration.
Construction and Quality Assurance
Every tank is proudly Made in the USA from corrosion resistant materials, providing long lasting service in demanding environments. The durable welds and high quality sealing components guarantee a leak free assembly. All electrical connectors and feed lines meet OEM specifications for fit and function. Before shipping, each kit undergoes a thorough inspection to verify pump performance and structural integrity. This attention to detail ensures that owners receive a product ready for immediate use and capable of supporting the most ambitious power upgrades.
