1965 Pontiac Lemans LS and LT EFI Fuel Tank Kit with 400 LPH Pump
Installing an LS or LT mill in a classic 1965 Pontiac Lemans demands a fuel system that keeps pace with sudden throttle demands and this EFI tank kit combines a 400 LPH pump with a calibrated sending unit to meet that need. It bolts into the factory mounting points on the A Body frame without cutting or welding to preserve underbody clearance and simplify installation. By submerging the Walbro pump in the fuel mass the design lowers operating temperature to reduce vapor lock risk during spirited driving. A direct sender link to the stock gauge cluster ensures accurate level readings for confident long distance runs.
Immersed Pump Cooling for Consistent Fuel Delivery
The fully submerged Walbro high-flow 400 LPH pump draws on the surrounding fuel for cooling, keeping its operating temperature low under sustained demand. Continuous liquid immersion prevents vapor lock during spirited driving or extended high load conditions. By eliminating heat-related flow drop-off, the design ensures crisp throttle response at every rpm. Cooler pump operation also extends service life by reducing wear on internal components. An added benefit is quieter operation as the fuel mass muffles mechanical noise, contributing to a refined driving experience.
Precision Formed Steel Tank Matching Chassis Geometry
Crafted from durable mild steel, the replacement tank mirrors the original contours of the Pontiac Lemans frame to maintain ground clearance and protect exhaust and suspension paths. OEM style lugs and bracket locations align with existing holes so installation requires no cutting or welding. The robust metal shell resists stress and fuel vapor exposure to support reliable performance in daily use or track outings. Manufactured in the USA to strict quality controls, this tank reflects American workmanship in every weld and bend. Retaining stock underbody lines preserves the classic profile while introducing modern EFI capability.
Calibrated Sending Unit for Accurate Fuel Monitoring
Engineered to factory tolerances, the sending module translates fluid level shifts into precise electrical feedback for the instrument cluster. A low friction float arm responds smoothly to cornering forces and pitching motion to avoid false readings in dynamic driving. Tight calibration resists drift even after long periods of service, giving drivers confidence on canyon roads or highway runs. Designed to integrate seamlessly with the stock wiring harness, it streamlines the wiring process for classic restorations. Accurate level data prevents surprises and helps plan fueling stops with precision.
Integrated Vent Filtration and Seal System for Leak Prevention
The vent filter captures moisture and debris while allowing smooth air exchange as fuel moves in or out of the tank. Precision molded gaskets seal every joint to maintain slight positive pressure and prevent leaks that could affect EFI performance. Together, these components protect internal surfaces from contamination and ensure steady injector output under sudden throttle changes. Maintaining a closed system under pressure also reduces the risk of evaporation and fuel odors. Durable filter element and sealing materials contribute to longevity in various weather and road conditions.
