Streamlined EFI Fuel Tank Solution for 1964-1967 Skylark LS LT

Designed for seamless integration into Buick Skylark models from 1964 to 1967 with LS or LT engines, the EFI Fuel Tank Kit pairs a Walbro 400 LPH pump with a precision level sender to maintain steady pressure and deliver accurate readings under extreme performance demands. Complete with factory-style straps, vent filter, gaskets, and hardware, it honors the classic profile while streamlining installation and supporting American manufacturing.

1964-1967 Buick Skylark LS and LT EFI Fuel Tank Kit with 400 LPH Pump

When fitting a modern LS or LT engine into a 1964-1967 Buick Skylark the original fuel tank often falls short of meeting the volume required by contemporary high power builds. This EFI Fuel Tank Kit brings a Walbro 400 LPH pump into the stock tank providing consistent pressure even under supercharged or heavily tuned conditions. Inside you get a precision fuel level sender, factory straps and a vent filter so installation is straightforward and tidy. Every component aligns with factory mounting points and preserves the Skylark's classic lines while providing reliable delivery for engines pushing beyond 550 hp.

Tailored Tank Conversion for Classic Skylark EFI Swaps

This kit is engineered specifically for 1964-1967 Buick Skylark and Gran Sport models, preserving the tank's original shape while upgrading its internal components. By retaining the factory mounting points and filler location, it fits like the stock unit yet delivers modern EFI capability. The in­tank module installs flush with the existing openings, ensuring no bodywork alterations are required. This approach maintains the car's classic profile and street appeal while supporting today's engine demands.

400 LPH Walbro Pump Ensuring Steady Fuel Flow

At the heart of the system lies a Walbro pump rated at 400 LPH, chosen for its proven reliability under extreme load. This high capacity output sustains consistent pressure in supercharged or heavily tuned engines pushing beyond 550 hp. Mounting the pump inside the tank reduces the risk of vapor lock and turbulence, as it remains submerged in fuel at all times. The result is smooth throttle response and confidence under hard acceleration.

Direct Fit Installation with OEM Style Components

Every component-from tank straps to gaskets and the vent filter-is designed for a straight swap into the original chassis locations. The included filler neck and hardware match factory specifications, eliminating fabrication or welding. This direct fit strategy cuts installation time and reduces the chance for leaks or misalignment. Installers benefit from clear bolt patterns and plug-and-play plumbing that adhere to the car's factory routing.

Precision Fuel Level Sender for Accurate Readings

The sending unit combines with the existing gauge harness to provide exact fuel level feedback, keeping the original dashboard functionality intact. Its calibrated float arm ensures consistency across the tank's full range, preventing surprises on long drives. By using OE-style electrical connectors, the sender integrates seamlessly with Buick wiring, avoiding extra adapters. This attention to detail preserves both visual authenticity and operational reliability.

For a smaller capacity fuel pump Kit at 255 LPH consider our 1964-1967 Skylark EFI Fuel Tank Kit - 255 LPH Pump which offers precise fit and steadfast delivery.
