1964-1967 Chevy Chevelle EFI Fuel Tank Kit for LS and LT Swap
The 1964 to 1967 Chevelle EFI Fuel Tank Kit - 400 LPH Pump addresses one of the most common hurdles in LS and LT swaps by delivering a reliable fuel supply under all driving conditions. With its precise sending unit and a fitment that matches original mounting points, the kit integrates directly into your Chevelle chassis. Drivers will notice consistent pressure and accurate gauge readings that help prevent fuel starvation during spirited runs or daily driving. Built around the Walbro 400 LPH pump, it supports high-demand engines while preserving the classic tank appearance.
Factory-Style Fitment for 1964 to 1967 Chevelle Chassis
This EFI fuel tank kit is engineered to match the original mounting points of your 1964-1967 Chevelle, ensuring a direct bolt-in upgrade with no frame modification required. By retaining the factory strap location and filler neck orientation, the kit maintains the vehicle's stock profile and preserves underbody clearances. Technicians and hobbyists alike benefit from the predictable alignment of the sending unit and pump module, which reduces trial-and-error fitting and minimizes installation time. The American-made tank shell also replicates the classic contours of the original fuel reservoir, so the visual upgrade remains virtually invisible.
Consistent Fuel Pressure from Walbro 400 LPH Pump
At the heart of the kit lies the Walbro 400 LPH in-tank pump, chosen for its ability to support supercharged engines or setups exceeding 550 hp without risk of fuel starvation. Its high flow rate ensures that peak power demands during acceleration or sustained high-speed cruising are met with stable pressure. The pump's design within the module also reduces heat soak by keeping the assembly submerged, which helps maintain output under extreme conditions. As a result, both daily drivers and track enthusiasts will notice smoother throttle response and a significant reduction in fuel delivery drop-off.
Accurate Sending Unit for Reliable Gauge Feedback
The included precision sending unit delivers true-to-level readings that eliminate common fuel-level guessing games. Calibrated for the internal geometry of this tank, the float mechanism moves freely through its full range, preventing false low-fuel warnings when cornering or climbing grades. This accuracy translates into confidence for long road trips and spirited canyon runs, as drivers can trust their instrument cluster to alert them well before the tank reaches empty. Consistent gauge performance also reduces the risk of fuel pump damage from running dry.
Comprehensive Kit Components Streamline Installation
Beyond the tank and pump, this conversion package includes a purpose-designed filler neck, vent filter, tank straps, gaskets, and all necessary hardware for an efficient assembly. The precision-cut gaskets ensure leak-free seals at every junction, while the vent filter guards against debris ingestion and maintains proper tank breathing. By supplying every fastener and mounting bracket, the kit saves builders from sourcing individual parts and keeps installation focused in one uninterrupted workflow. Even first-time EFI installers will appreciate the clear path this all-in-one design provides toward a functional, modern fuel system.
