1968 Impala EFI Fuel Tank Kit with 400 LPH Pump
For a modern fuel system swap on a 1968 Impala, this EFI tank kit supports the 400 LPH pump and delivers the stable flow required for demanding LS conversions. Its integrated in tank module and sending unit are engineered to fit precisely in the Impala frame without extensive modification. Installation is streamlined with all straps filters and hardware included so you can swap tanks and wire the pump with confidence.
400 LPH Walbro Pump Performance
The 400 liter per hour Walbro fuel pump at the heart of this EFI tank kit is engineered to deliver a high-flow, steady stream of fuel for setups that demand reliable horsepower on tap. Whether the Impala is boosted or naturally aspirated, the consistent output prevents fuel starvation under heavy throttle, supporting up to 750 horsepower potential. By maintaining a precise pressure range within the in tank module, the pump also reduces heat buildup and stress on fuel system components. The result is a smoother throttle response and confidence that your classic cruiser will run strong from street cruising to strip duty.
Integrated In Tank Module and Sending Unit Precision
Combining the pump, filter sock, and fuel level sender into one factory styled module streamlines both wiring and plumbing under the vehicle. This integration ensures the sending unit sits at the optimal height in the tank, yielding accurate readings across varying fuel loads. The robust electrical connectors are designed to resist corrosion in the tank's harsh environment, while the built in filter sock traps debris before it reaches the pump. Together, these elements simplify diagnostics and maintenance by keeping critical components in a single accessible assembly.
Engineered Fitment for 1968 Impala B Body Chassis
Each steel tank is stamped and welded to replicate the exact dimensions of the original 1968 Impala unit, ensuring perfect alignment with the factory frame rails and body mounts. This precision fit design avoids the need for hammering or cutting into the floor pan, preserving the structural integrity and classic underbody lines. The tank's contours also accommodate the stock exhaust routing and rear suspension components without interference. By matching the vehicle's original geometry, installation becomes a straightforward swap and keeps the chassis true to its factory configuration.
DIY Friendly Installation with Complete Hardware
This kit arrives with every strap, gasket, vent filter, filler neck and bolt needed for a one-piece replacement of your old tank assembly. Pre fitted flanges and matched mounting brackets allow you to simply lift out the old tank and lower in the new one without hunting down additional parts. Clear instructions guide you through each step, from disconnecting the fuel lines to wiring the pump, making it ideal for home mechanics. The result is a clean, professional installation that restores fuel delivery performance without a trip to the shop.
