LS and LT Swap EFI Fuel Tank Kit for 1965 Pontiac Lemans
When adapting a modern LS or LT powerplant to a 1965 Pontiac Lemans A-Body, steady fuel delivery can make or break performance. This EFI fuel tank kit includes a 400 LPH pump to maintain consistent flow under heavy throttle and a calibrated sending unit that keeps your gauge readings accurate. Bolting directly into the original mounting points and featuring a steel tank shaped to the factory contour, it preserves the classic profile while ensuring a clean fit.
In Tank 400 LPH Fuel Pump for LS and LT Applications
The in tank 400 LPH Walbro pump maintains a constant flow of fuel even when your LS or LT engine exceeds 550 horsepower. Being fully submerged in fuel keeps the pump cool under sustained throttle events and virtually eliminates vapor lock during hard acceleration. This design supports both naturally aspirated and boosted setups, delivering crisper throttle response and consistent performance. By ensuring steady volume under extreme demand, the pump safeguards against fuel starvation and power drop.
Factory Contour Steel Tank for Seamless OEM Fit
Engineered to follow the original outline of the 1965 Pontiac Lemans A Body, the steel tank bolts directly into the factory mount points with no frame modifications required. Tank straps, filler neck, and hardware reuse existing holes, preserving the vehicle's classic silhouette while integrating modern EFI components. This seamless fit saves time during installation in tight wheelwells and keeps the car's period correct appearance intact. The result is a functional upgrade that respects the Lemans heritage.
Precision Fuel Sending Unit for Accurate Gauge Readings
The calibrated sending unit converts real time fuel levels into precise electrical signals for the stock gauge cluster, eliminating surprises at the pump. Its float mechanism moves freely within the tank, delivering reliable readings through temperature changes and constant vibration. Manufactured to OEM tolerances, the sender resists wear and maintains accuracy over thousands of miles. Accurate gauge data lets you manage fuel stops with confidence on long drives.
Optimized Vent Filter and Gasket Sealing for System Integrity
A dedicated vent filter prevents airborne debris from entering the tank while allowing proper breathing as fuel is consumed or refilled. High quality gaskets create an airtight seal around every joint, stopping leaks and preserving stable system pressure under all driving conditions. Together with the pump module and sending unit, these components form a unified system that guards against fuel contamination and loss of pressure. This comprehensive approach ensures long term reliability for your EFI conversion.
Count on consistent fuel delivery for your LS or LT swap. To complement this with a smaller capacity fuel pump kit at 255 LPH see our 1965 Pontiac Lemans EFI Fuel Tank Kit - 255 LPH Pump.
