1970 Chevy Monte Carlo LS Swap EFI Fuel Tank Kit with 255 LPH Pump
Installing an LS powerplant into a 1970 Chevy Monte Carlo often leads to fuel starvation under hard acceleration and this EFI Fuel Tank Kit with a 255 LPH pump keeps flow steady for up to 550 horsepower. The steel reservoir contours to A Body frame rails and retains the original filler neck and vent filter to preserve stock looks and avoid brake line alterations. By submerging the Walbro pump in fuel the assembly runs cooler and resists vapor lock during spirited runs. Installers will appreciate the direct bolt on fitment and precision sending unit that hold pressure stable and streamline the LS swap process.
Precision Frame Alignment for 1970 Monte Carlo
This fuel tank kit is engineered to match the underbody geometry of a 1970 Chevy Monte Carlo A Body chassis, avoiding cutting or fabrication of custom brackets. By contouring to the original frame rails, it preserves ground clearance and the factory brake line path without modification. Retaining the stock filler neck and vent filter not only maintains the classic appearance but also keeps service access straightforward. Installers will find that the supplied straps and hardware lock directly to existing mounting points, eliminating alignment guesswork and shortening installation time.
Cooling Benefits of Submerged Walbro Pump
Housing the 255 LPH Walbro pump entirely inside the reservoir allows continuous fuel flow to envelop the pump housing and draw away heat. Lower operating temperature extends component life and minimizes the risk of vapor lock under hard acceleration or in hot climates. Immersion also acts as a sound barrier, reducing audible pump noise in the cabin. An integrated bypass valve further smooths pressure surges when you stomp the throttle, ensuring seamless delivery on demand.
Corrosion Resistant Steel Reservoir Construction
Fabricated from corrosion resistant steel, the reservoir stands up to moisture, road debris, and temperature swings without rusting over time. Precision welding secures the pump module and sending unit flanges, creating a stiff structure that resists vibration and chassis flex during spirited driving. Sealing surfaces use gaskets rated for electronic fuel injection and stainless hardware to maintain a leak free barrier. This rugged build quality delivers lasting reliability for daily use and occasional track duty.
Improved Fuel Delivery for EFI Conversion
Switching to this EFI tank kit transforms fuel metering by pairing a precision sending unit with the high capacity pump to prevent lean spikes that can damage internal parts. Consistent pressure keeps atomization rate stable across steady cruising or sudden throttle bursts, which enhances throttle response and overall drivability. Fuel efficiency benefits from closed loop control in the EFI system, while reliable flow up to 550 hp protects pistons and valves under high load. The result is confident acceleration and engine safety in every driving scenario.
