1968 Impala EFI Fuel Tank Kit with 400 LPH Pump
Installing a reliable fuel supply is vital for any LS engine conversion in a 1968 Impala and the 1968 Impala EFI Fuel Tank kit - 400 LPH Pump answers that need with a purpose built design. The heavy duty steel tank is custom engineered to match 1968 B Body frame rails and preserve factory mounts while guiding a direct tank swap requiring minimal modification. The internal fuel pump module combines a 400 LPH Walbro unit with the integrated fuel sending unit. Complete straps, filler neck, vent filter, gaskets and hardware support a one session installation. Installation hardware is organized for quick access and the DIY friendly layout guides wiring and plumbing steps with minimal learning curve.
Precision Fit for 1968 Impala
This fuel tank kit is custom engineered for a perfect fit in the 1968 Impala built on the B Body frame. It retains factory mounting points and chassis clearance without modification. The tank shape follows the original contours to maintain ground clearance and drive shaft alignment. This approach preserves the structural integrity of the vehicle floor and reduces installation time by eliminating the need for trial fitting or trimming.
Optimized Fuel Delivery
The kit features a 400 LPH Walbro pump that delivers the flow rate required by supercharged or high power engines. Locating the pump inside the tank reduces the risk of vapor lock and improves pressure consistency at the rail. The integrated pump module also includes a fuel sending unit calibrated to the Impala tank volume, ensuring accurate level monitoring and precise flow control under heavy acceleration or sustained high load conditions.
Built for Durability and Ease of Installation
Constructed from heavy duty steel, this tank resists pressure and protects against minor impacts. Its design supports a direct tank swap, allowing removal of the original unit and installation of this kit without welding or complex fabrication. Simplified access to the mounting flange and fittings ensures straightforward maintenance and component replacement throughout the vehicle's life.
LS Conversion Ready
While tailored to the 1968 Impala chassis, the tank also integrates with LS engine conversion projects. When used with MuscleRods LS mount kits, it maintains proper engine alignment and optimizes drivetrain angle. Coordinating tank position with mount geometry prevents undue stress on fuel lines and mounting brackets during operation. This cross platform solution makes it a versatile choice for restomods, fuel delivery upgrades, and performance driven restorations.
