1968-1969 Chevy Chevelle LS Swap EFI Fuel Tank Kit
If you are swapping an LS engine into a 1968-1969 Chevelle A Body, this EFI Fuel Tank Kit tackles the tight chassis envelope under the stock rails while laying the groundwork for sustained power delivery. Its notched tank design carves clearance for modern exhaust headers and full suspension movement without modifying factory mounting points. Equipped with a 255 LPH Walbro pump inside a heavy gauge steel shell, the system shields components from engine heat and road debris. Built with internal baffles, it keeps the inlet submerged during hard stops to support up to 550 horsepower reliably.
Precision Notched Tank Geometry for Header and Suspension Clearance
The notched contour along the tank rail is engineered to carve out vital clearance for modern header routing and full rear suspension travel without changing the stock rails. By removing material only where needed, the design maintains original fuel capacity and preserves chassis integrity. This tailored profile prevents contact between exhaust components and the steel shell, reducing the risk of wear or dents. It also supports smooth suspension articulation under load, eliminating pipe chafing in tight spaces. Crafted specifically for LS engine placement in late sixties A body platforms, it delivers a seamless fit without modification.
Integrated In Tank Delivery Module with 255 LPH Pump
The kit includes a complete in tank delivery module housing a 255 liters per hour pump rated for up to 550 horsepower applications. Enclosing the pump, sending unit, and wiring inside the tank shields these parts from engine bay heat and road debris, which helps prevent vapor lock and premature wear. Internal routing keeps the pump inlet submerged during hard stops and corners, ensuring consistent pressure and flow. Positioning the module inside the tank also reduces operating noise for a quieter ride. This consolidated assembly simplifies connections, offering a neat layout with minimal plumbing adjustments.
Heavy Gauge Steel Shell and Baffle System for Fuel Stability
Manufactured from thick steel plate, the tank resists deformation from road impacts and stands up to ethanol blends and moisture exposure. Welded baffles divide the interior, managing fuel movement during rapid acceleration or braking to keep the pump inlet immersed. This prevents cavitation and lean spots that can cause hesitation under load. The robust shell also provides added protection against heat soak, keeping fuel cool under extended use. Together, the strength and fluid control ensure uninterrupted delivery in both daily driving and spirited track sessions.
True Bolt In Installation with Original Mounting Hardware
Designed for a true bolt in install, this fuel tank kit uses the factory straps, filler neck, and fuel lines for a hassle free process. The mounting holes align precisely with the original body rails so installers can secure the assembly using basic hand tools and stock hardware. Included gaskets, vent filter, and filler components drop in without adapters, reducing the chance for leaks or fitment errors. Most installs can be completed within hours, speeding project timelines and cutting labor costs. The end result is a clean setup that retains the Chevelle's factory appearance and performance.
