1968-1969 Chevy Chevelle A-body EFI Fuel Tank Kit for LS and LT Swaps
Installing a modern LS or LT powerplant into a 1968 or 1969 Chevelle often stalls when the stock tank interferes with frame rails and exhaust tubes. This notched EFI fuel tank kit is laser cut to trace the A-body undercarriage geometry with thousandth inch precision, delivering clearance around exhaust, tire envelopes and sensor bosses without trimming. It houses a 400 LPH pump fully immersed in fuel to maintain consistent pressure under supercharged or 550 horsepower loads. With sending unit, filler neck, straps and gaskets included, installers mount the tank and move straight to engine management calibration.
Precision Crafted Notches for A Body Chassis Clearance
The fuel tank's notched design follows the 1968 and 1969 Chevelle undercarriage with thousandth-of-an-inch accuracy, ensuring exhaust pipes, frame rails and suspension travel remain unobstructed. These contours align with tire envelopes and sensor mounts to preserve factory mounting positions, eliminating the need for cutting or test fitting. By matching the original chassis geometry, installers maintain structural integrity and reduce project time while avoiding rubbing or abrasion on hoses and sensors. This level of precision also safeguards against damage during spirited driving, keeping lines and components free from stress that can cause premature wear. The result is a direct-fit solution that retains the classic underbody appearance without compromise.
Fully Immersed Pump for Heat Management and Vapor Lock Prevention
Positioning the 400 LPH pump entirely inside the steel shell immerses it in a fuel bath that serves as a natural coolant, limiting heat soak under high load or boost conditions. Surrounding fuel temperature remains lower than ambient underhood heat, which helps prevent vapor lock during hard acceleration or sustained cornering. This internal location also shields the pump from road debris and contaminants, reducing strain on downstream filters and extending service intervals. Shorter fuel line runs inside the tank cut leak points and simplify routing, improving safety. Overall, this arrangement delivers consistent pressure for reliable engine response, even in supercharged or 550-horsepower applications.
Unified Fuel System Kit for Streamlined Installation
This complete assembly arrives with the pump module, sending unit, filler neck, vent filter, straps and all necessary gaskets and hardware, so installers can bolt it onto factory rails without hunting for adapters. Components precisely match original fill and vent port dimensions, eliminating custom fabrication and reducing install time. Consolidating parts in a single kit not only cuts potential leak paths but also ensures proper alignment of all interfaces, from lines to sensors. Installers can secure the tank and proceed directly to calibration, shortening project timelines. By delivering every required piece, the kit simplifies staging, inventory management and future service access.
Corrosion Resistant Steel and Rigorous Testing for Long Term Reliability
Fabricated from corrosion resistant steel and finished with a clear protective coat, the tank withstands moisture, road salt and modern fuel blends without compromise. Every weld seam endures pressure testing and vibration cycles that simulate real world cornering forces and highway conditions, guaranteeing leak-free performance. Assemblies undergo multiple inspections to verify fitment accuracy and structural soundness before shipping. This validation process provides confidence that the tank will handle spirited driving and high output setups without failure. The combination of robust materials and stringent quality control delivers a dependable foundation for any LS or LT engine swap project.
