1965 Pontiac Lemans A-Body LS/LT EFI Fuel Tank Kit 400 LPH Pump
Swapping in a modern LS or LT engine for your 1965 Pontiac Lemans A Body hinges on steady fuel supply and this EFI tank kit features a 400 LPH Walbro pump to guard against fuel starvation under high demand. It also includes a precision sending unit and vent filter to preserve accurate gauge readings and proper system breathing. Every component bolts into the original mounting points so installation stays straightforward even in confined spaces. With a steel tank shaped to match factory contours, this kit supports your powerplant while keeping the classic profile intact.
Precision Fuel Delivery with the 400 LPH Walbro Pump
The in-tank 400 LPH Walbro pump is engineered to maintain a constant flow rate even when your LS or LT engine is pushed beyond 550 horsepower. By operating fully submerged in fuel, the pump stays cool under sustained load and resists vapor lock that can cause momentary starvation during hard acceleration. Delivering a steady supply of premium fuel, it supports both naturally aspirated and supercharged configurations to enhance throttle response and overall drivability. This design choice ensures your modern powerplant receives the volume it needs when you demand maximum performance.
OEM Style Integration for 1965 Pontiac Lemans A Body
Every component in this EFI fuel tank kit is dimensioned to match the original mounting locations of a 1965 Pontiac Lemans or Tempest A-Body chassis, so no custom brackets or frame modifications are required. The replacement steel tank is formed to follow the factory contour, preserving the classic profile while adding modern function. Tank straps, filler neck, and hardware all bolt into place using existing holes, making installation straightforward in tight quarters. By retaining the stock appearance and footprint, this kit lets you upgrade confidence without altering the vehicle's beloved lines.
Accurate Gauge Performance from the Precision Sending Unit
The included sending unit is calibrated to work seamlessly with your original fuel gauge cluster, delivering consistent readings under all driving conditions. Its float mechanism travels freely in the tank, translating real-time fuel levels into precise electrical signals for your dash. This reliability eliminates guessing games at the pump and lets you manage long drives without worries. Built to OEM tolerances, the sender resists wear and maintains accuracy through temperature swings and constant motion.
Optimized Venting and Sealing for Complete System Reliability
A dedicated vent filter prevents airborne debris from entering the tank while allowing proper breathing as fuel is drawn down or replenished. Robust gaskets form an airtight seal around every joint, stopping leaks and ensuring system pressure remains stable. Together with the precision pump module, these elements protect against fuel contamination and preserve consistent operation under extreme driving demands. This cohesive approach to ventilation and sealing underpins the long-term integrity of your EFI conversion.
