EFI Fuel Tank Kit for 1968-1969 Chevy Chevelle LS/LT Swap
For builders swapping an LS or LT engine into a 1968 to 1969 A-body Chevelle clearing tight frame curves without cutting often slows down a project. This EFI fuel tank kit tackles that issue by matching notched contours to the rails and exhaust geometry while housing a 400 LPH pump fully inside the steel shell for steady pressure under supercharged or 550 hp demands. By immersing the pump module in fuel the kit also reduces heat soak and prevents vapor lock during spirited cornering. Every sending unit, filler neck, strap and gasket ships ready to bolt onto factory mounts so installers skip fabrication and get straight to tuning their new motor.
In Tank Pump Immersion for Consistent Pressure
Positioning the 400 LPH pump entirely within the steel shell takes advantage of surrounding fuel as a natural coolant, limiting heat soak and extending component life under sustained high demand. By submerging the pump module, the design prevents vapor lock even when supporting boosted or 550+ horsepower engine builds, delivering steady fuel pressure through aggressive acceleration or hard cornering. This immersion approach also dampens mechanical noise, improving cabin refinement without adding external insulation. In addition, enclosing the pump inside the tank offers a barrier against road debris and environmental contaminants, reducing filtration loads and service intervals. Fuel line runs become more direct, streamlining the plumbing layout and cutting potential leak points.
Precision Contour Matching for Easy Frame Clearance
Laser cutting and meticulous dimensional control ensure the tank notches follow the 1968-69 A body frame curves, exhaust tubes, tire envelopes and factory sensor locations within thousandth-of-an-inch tolerances. This precision alignment eliminates time-consuming test fits and on-site modifications, preserving original rail mounts and chassis geometry. With clearance areas preformed for hard points, installers avoid interference under heavy cornering loads that can lead to starvation or abrasion. The result is a genuine plug and play fuel solution that maintains structural integrity and prevents damage to surrounding components. Builders can rely on exacting contours to speed up every LS or LT conversion project.
Complete Fuel Assembly for Rapid Setup
This all-in-one kit arrives with every element required to mount onto factory rails without additional brackets or adapters. Alongside the pump and in-tank module, the package includes sending unit, filler neck, vent filter, tank straps, gaskets and mounting hardware, all engineered to match original fill and vent connections. By consolidating these parts in a single assembly, the design cuts down on installation time and minimizes potential leak paths. Technicians can bolt the system in place and move directly to calibration of the engine management system. The unified approach streamlines maintenance access and simplifies future service tasks.
Rigorous Durability Testing for High Demand Use
Constructed from corrosion resistant steel treated with a durable protective finish, the tank resists moisture, road salt and fuel additives under varied driving conditions. Critical weld seams undergo pressure and vibration tests that simulate real-world cornering forces and highway miles, assuring leak-free performance throughout the life of a high output swap. Every assembly passes a series of quality control inspections, verifying structural integrity before shipment. This validation process gives builders confidence that the tank can handle the rigors of spirited driving and boost levels without compromise. It's a reliable foundation for any LS or LT engine conversion.
Backed by rigorous durability testing and precision fit, this EFI fuel tank kit delivers reliable performance throughout your LS and LT conversion. For a smaller capacity fuel pump Kit at 255 LPH see our 1968-1969 Chevelle 255 LPH notched pump Tank Kit (notched).
