LS and LT EFI Fuel Tank Kit for 1964 Pontiac GTO
When converting a 1964 Pontiac GTO to LS or LT power, the standard tank often cannot keep up with modern fuel demands during spirited driving. This 1964 Pontiac GTO EFI Fuel Tank Kit - 400 LPH Pump installs effortlessly in place of the original reservoir and features a fully submerged Walbro pump to maintain stable pressure even in supercharged or 550 hp setups. With a calibrated sending unit tuned to match the factory gauge output, drivers retain accurate fuel level readings without modification, while a durable vent filter and precision sealing gaskets safeguard against debris and moisture.
Precision Calibrated Sending Unit for Stock Gauge Performance
The sending unit in this 1964 Pontiac GTO EFI Fuel Tank Kit replicates the exact resistance curve of the factory system, ensuring the stock gauge behaves exactly as intended. By matching the original output, this module prevents erratic needle swings and false empty warnings that can accompany generic aftermarket senders. The precision calibration keeps fuel level readings linear under acceleration or cornering, so drivers can rely on accurate information during spirited runs. Arriving pre adjusted and ready for plug-and-play installation, it streamlines setup and eliminates the need for additional gauge tuning.
Submerged Pump Configuration Preserving Fuel Pressure Under Load
This kit's 400 LPH Walbro pump sits fully inside the tank, surrounded by fuel to provide constant cooling that prevents heat-related pressure drop. In LS and LT applications running supercharged or above 550 horsepower, this submerged arrangement stops vapor lock and maintains consistent flow even during long high-RPM pulls. The continuous fuel bath around the pump housing also reduces noise and helps sustain peak performance on the strip or road course. End results are rock-steady pressure, reliable throttle response, and uninterrupted engine operation under extreme demands.
OEM Style Integration Maintaining Classic GTO Underbody Profile
Engineered to bolt into the original frame points of a 1964 Pontiac GTO, Lemans, or Tempest without altering chassis or suspension geometry, this tank keeps the underbody looking factory-fresh. The filler neck, straps, and mounting hardware mirror the stock layout, so no cutting, welding, or crossmember modifications are required. Maintaining the factory footprint safeguards resale value and preserves show-quality appearance while supporting modern performance upgrades. Even the vent filter and gaskets are positioned to match stock clearances and prevent interference with exhaust or brake components.
Modular Assembly Streamlining Maintenance Access
Combining pump, sending unit, vent filter, and sealing gaskets into a single serviceable module reduces potential leak points and simplifies routine tasks. A single set of fasteners releases the entire assembly, allowing quick access for filter swaps or pump replacements without dismantling surrounding underbody parts. Pre-routed electrical connectors and included hardware guide a straightforward reassembly, even in tight quarters. This unified design enhances system reliability and shortens maintenance downtime over the life of the installation.
