LS EFI Fuel Tank Kit for 1962-1965 Chevy II/Nova X-Body
When retrofitting a first generation Chevy II or Nova X Body with an LS engine achieving reliable fuel flow is critical. The 1962 to 1965 Chevy II EFI Fuel Tank Kit, 400 LPH Pump, slides into the stock mounting points for a cut free installation that preserves factory ride height and avoids interference with rear suspension or exhaust tubing. By submerging the Walbro unit in cool fuel and shortening the feed path the design prevents heat soak and reduces vapor lock while delivering steady fuel flow during hard acceleration and sustained cornering. Installers appreciate a complete package that includes sender straps filler neck and hardware to streamline each build.
Direct Fit Engineering for 1962 to 1965 Chevy II X Body
This fuel tank kit is precisely contoured to slide into the original mounting points of first generation Chevy II and Nova X body models without altering the chassis. By matching the factory underbody clearances around the rear suspension and exhaust channels, the design preserves the original ride height and prevents any interference with road travel. The filler neck and vent lines align exactly with the stock routing, so installers can connect all lines without trimming or welding. This attention to fitment tolerance reduces labor time and ensures every installation yields consistent results on each build.
Submerged Pump Design for Stable Fuel Delivery
Housing the 400 LPH Walbro unit fully below the fuel level keeps the pump motor cool and virtually eliminates the risk of vapor lock under heavy load or sustained cornering. Positioning the pickup at the tank's lowest point shortens the feed path and delivers uniform pressure to the injectors, even during hard acceleration or abrupt throttle transitions. Laboratory testing of the pump's balanced rotor assembly confirms reliable output for naturally aspirated and boosted LS powerplants up to 550 hp. The module's self contained design also quiets operational noise and allows swift access for servicing or replacement.
Comprehensive Kit Components Streamline Installation
This all in one package includes every component required to convert a classic Chevy II or Nova to LS EFI power, from the pump module and sending unit to tank straps, gaskets, hardware, filler neck and vent filter. Each piece is precisely matched and factory tested to work together, eliminating mismatches that can cause leaks or pressure loss. Pre sized sealing surfaces and proven connections ensure a tight fit immediately upon assembly, reducing the likelihood of post installation fuel odors. By combining all parts in a single kit, professionals and weekend enthusiasts avoid sourcing delays and simplify project planning.
USA Built Construction for Durability and Precision
Proudly manufactured in the United States, the steel fuel tank and pump module are built to stringent quality standards that guarantee both durability and fit accuracy. Tight tolerance stamping and weld control deliver consistent chamber geometry so every tank meets the same exacting criteria. Domestic production also allows rigorous inspection of each component before shipping to ensure long term performance in harsh conditions and demanding driving scenarios. This commitment to local craftsmanship gives builders confidence in a premium product backed by repeatable quality.
