LS and LT EFI Fuel Tank Kit for 1964 Pontiac GTO
When fitting a modern LS or LT engine into a classic Pontiac GTO chassis, reliable fuel delivery becomes essential, and the 1964 Pontiac GTO EFI Fuel Tank Kit - 400 LPH Pump addresses this challenge head on. Featuring the renowned 400 LPH Walbro pump, this tank maintains consistent pressure under spirited acceleration while supplying LS or LT engines with the volume they demand. Each component bolts in place without cutting or welding, preserving the original frame integrity of your GTO. With precise fuel level readings from the calibrated sending unit, unexpected fuel issues become a thing of the past.
400 LPH Walbro Pump Ensures Consistent High Output Fuel Supply
The heart of this EFI tank kit is the in-tank 400 LPH Walbro pump, chosen for its ability to sustain fuel delivery under extreme acceleration and high engine loads. Capable of supporting supercharged setups and power levels exceeding 550 horsepower, it prevents pressure drop and starvation when you demand maximum throttle response. By remaining submerged in fuel, the pump benefits from constant cooling, which prolongs service life and maintains steady flow rates. This design also reduces the risk of vapor lock, ensuring reliable performance whether you're cruising or pushing your GTO to its limits.
Calibrated Sending Unit for Reliable Fuel Level Accuracy
Precise fuel management starts with an accurately calibrated sending unit that communicates directly with your factory gauge. Engineered to match the original stock measurement curve, it eliminates the common discrepancies that leave drivers guessing at their remaining range. Consistent readings not only reduce the risk of running dry but also help you plan fueling stops with confidence, especially on spirited drives or long open-road excursions. The unit's robust construction guarantees long-term stability, so you won't face sudden failures or erratic gauge behavior.
OEM Style Direct Fit Simplifies Installation
This fuel tank kit is crafted for a seamless swap into the 1964 Pontiac GTO, Lemans, or Tempest without requiring frame alterations or custom fabrication. All components are pre-assembled and designed to bolt into existing mounting points, cutting installation time and labor to a minimum. Full hardware, gaskets, and tank straps are included to maintain original frame integrity and appearance, preserving the classic look of your chassis. The kit's straightforward approach lets DIY enthusiasts and professional shops alike complete the upgrade in a single weekend session.
Integrated Filtration Safeguards Engine Longevity
Clean fuel is critical for modern LS and LT injector systems, and this kit delivers with a built-in vent filter and high-quality sealing gaskets. The vent filter traps airborne contaminants before they can enter the tank, while precision gaskets eliminate leaks and prevent dirt ingress. By ensuring that only pure fuel reaches the pump and injectors, the system helps prevent premature wear and clogging, extending the life of your entire fuel delivery network. These protective features translate directly into fewer maintenance intervals and more time behind the wheel.
