1970-1973 Camaro/Firebird LS and LT EFI Fuel Tank Kit
For builders installing an LS or LT powerplant into a 1970-1973 Camaro or Firebird, ensuring fuel delivery matches the demands of EFI engines above 550 horsepower is critical. This sealed EFI fuel tank kit includes a tank module with 400 LPH Walbro pump rated for supercharged or over 550 HP applications and comes complete with sending unit, filler neck, gaskets, installation hardware and O ring sealed premium vent filter. Bolt in installation on F Body chassis uses tank straps on factory frame rails for precise fitment and maintains stock gauge accuracy while all components are engineered for high flow injection compatibility in LS and LT applications.
Fuel Delivery Capacity and Performance
The 400 LPH Walbro pump at the core of this kit delivers the volume required to support engine outputs above 550 hp with ease. By maintaining consistent fuel pressure under sustained load and during rapid throttle changes, it prevents lean spikes that can lead to detonation. This reliable delivery framework preserves internal components and enables aggressive tuning for both naturally aspirated and supercharged setups without compromise.
Powertrain Compatibility and Precision Integration
Engineered exclusively for compatibility with LS and LT powerplants, this tank kit integrates seamlessly with MuscleRods mounts to secure correct engine placement and optimal drivetrain angles. This targeted integration eliminates misalignment issues common in retrofit installations, reducing driveline stress and vibrations. Precise fitment maintains safety margins and improves power transfer efficiency through the transmission and rear axle.
Flow Optimization and Seal Integrity
Optimized for high-flow fuel injection applications, the kit's internal baffle design ensures steady supply during cornering, acceleration, and braking. Premium vent filters prevent particle ingestion, while durable O ring seals create a leakproof environment. These components work in concert to maintain clean fuel under pressure, reducing contamination risks and safeguarding injectors and pump longevity in demanding driving scenarios.
Chassis Fitment and Installation Efficiency
Constructed to bolt directly to the original mounting points of 1970 through 1973 F body chassis, this kit streamlines installation and eliminates fabrication. All necessary hardware and engineered brackets are included for a consistent fit. The tank's durable construction resists corrosion and supports the demands of daily driving or road course duty. Installation time is minimized without sacrificing structural integrity.
