EFI Fuel Tank Kit with 400 LPH Pump for 1964-1967 Chevy Chevelle LS and LT Swaps
When retrofitting a classic Chevelle for modern LS or LT power the 1964-1967 Chevelle EFI Fuel Tank Kit - 400 LPH Pump delivers a dependable in-tank solution that aligns with original mounting points and keeps the chassis unaltered. This kit integrates a precision sending unit calibrated to the tank geometry and a Walbro pump capable of supporting over 550 hp applications without fuel starvation. Matching the factory strap location and filler neck orientation preserves the clean underbody profile while ensuring accurate gauge readings under spirited driving conditions.
Exact Fitment for 1964 to 1967 Chevelle Chassis
This fuel tank kit is engineered to align precisely with the original mounting points of the 1964-1967 Chevelle, so there is no need for frame alterations or custom brackets. The sending unit and pump module match the factory strap locations and filler neck orientation, preserving underbody clearance and the vehicle's classic proportions. Installers benefit from predictable alignment that cuts down on trial and error, while the American-made shell mirrors the contours of the stock reservoir for an invisible upgrade. Consistent fitment also reduces alignment issues that can lead to leaks or rattles over time.
Stable Fuel Delivery with Walbro 400 LPH Pump
At the core of this kit is a Walbro 400 LPH in-tank pump selected for its ability to support engines exceeding 550 hp without risking fuel starvation. By operating submerged in the tank, the pump resists heat soak and maintains steady pressure during hard acceleration or high-speed cruising. This reliable flow rate delivers smoother throttle response and eliminates fuel delivery drop-off commonly experienced in high-demand applications. Builders and drivers alike appreciate the confidence that comes from a pump designed to meet modern power requirements.
Precision Sending Unit Ensuring Accurate Gauge Feedback
The included sending unit is calibrated to the internal shape of this tank, offering true-to-level readings that eliminate guesswork when monitoring fuel reserves. Its float moves freely through the full range, preventing false low-fuel warnings during cornering or uphill climbs. Accurate feedback not only gives drivers peace of mind on long trips but also protects the pump from damage caused by running dry. Consistent gauge performance helps avoid unexpected stops and keeps engine performance uninterrupted.
Comprehensive Kit Components for Streamlined Installation
Beyond the tank and pump, this all inclusive package provides a purpose-designed filler neck, vent filter, tank straps, gaskets and every piece of hardware needed for a straightforward assembly. Precision-cut seals ensure a leak-free connection at every junction, while the vent filter keeps debris out and maintains proper tank breathing. By supplying all mounting brackets and fasteners, the kit spares builders from sourcing individual parts and accelerates the installation process. Even first-time EFI installers will find that the complete hardware set keeps work focused and efficient.
