1965 Pontiac Lemans A-Body LS and LT EFI Fuel Tank Kit with 400 LPH Pump
If you are building a LS or LT powerplant for your 1965 Pontiac Lemans A Body chassis and require reliable fueling under heavy loads, the 1965 Pontiac Lemans EFI Fuel Tank Kit - 400 LPH Pump delivers a purpose built EFI conversion solution. This made in the USA kit uses a tank with direct OEM fit and minimal modification for fast installation and includes an in tank fuel pump module rated at 400 liter per hour suitable for more than 550 hp setups. A precision fuel sending unit provides accurate gauge readings while gaskets, filler neck, tank straps and installation hardware complete the kit. The submerged pump design helps maintain cooler operation and steady output, ensuring sudden throttle inputs are met with consistent pressure from the sealed vent filter and steel tank structure.
Model Specific Application
The 1965 Pontiac Lemans EFI Fuel Tank Kit is engineered exclusively for 1965 Pontiac Lemans and Tempest vehicles undergoing LS or LT engine conversions. This kit integrates with MuscleRods mounts to ensure precise engine placement and optimal drivetrain angles. By maintaining exact alignment, stress on fuel lines and chassis components is minimized, and unwanted vibration is dampened. The result is a fuel system that operates reliably under dynamic load and preserves the integrity of the original frame geometry.
Efficient Pump and Sensing Technology
At the core of this kit is a high-flow Walbro 400 LPH pump capable of supporting supercharged or over 550 HP setups. Housed inside the tank, the pump delivers consistent pressure under high demand and reduces the risk of vapor lock by eliminating long external feed lines. The low electrical draw and near-silent operation ensure uninterrupted fuel delivery during spirited driving or drag strip launches. A precision fuel sending unit provides accurate fuel level readings, calibrated to match the tank's true capacity. Drivers benefit from trustworthy gauge feedback that virtually eliminates fuel starvation surprises.
Precision Fit and US Craftsmanship
This EFI conversion tank features a direct OEM style fit requiring minimal modifications to the original sheetmetal and support straps. Each mounting point aligns with factory dimensions, preserving ride height and ground clearance. Crafted in the USA from corrosion-resistant materials, the tank resists chemical breakdown from today's ethanol blends. Finish details include a durable protective coating that safeguards against abrasion and moisture intrusion. With preconfigured wiring harness adapters and a ready-to-install design, this kit streamlines the conversion process while delivering a modern fuel system that complements the classic profile of the 1965 Pontiac Lemans.
