1968 Impala EFI Fuel Tank Kit with 255 LPH Pump
When an LS powerplant finds its way into a 1968 Impala, dependable EFI flow becomes essential. The 1968 Impala EFI Fuel Tank kit - 255 LPH Pump combines a 255 LPH Walbro pump with a steel reservoir shaped to match the B body frame rails, allowing use of the factory mounting bosses without alterations. This in tank pump module design maintains continuous fuel coverage under hard acceleration to prevent vapor lock for engines up to 550 hp. Complete with a calibrated sending unit, filler neck, vent filter, tank straps, gaskets and mounting hardware, the kit delivers everything needed for a precise LS engine conversion with no parts chasing.
Precision B-Body Fitment
The 1968 Impala EFI Fuel Tank kit has been engineered with exacting attention to the original B-Body architecture, ensuring seamless integration under the rear of a 1968 Impala. CAD-based shaping aligns the filler neck and vent outlets to the factory opening, so no alterations to the trunk pan or chassis rails are required. By matching the contours of the stock floor pan and mounting bosses, the kit maintains proper ground clearance and secures the tank in its intended position for both safety and appearance.
Advanced Fuel Delivery Capacity
At the heart of this kit is a 255 LPH Walbro pump proven to support up to 550 hp. The internal pump module is suspended within the tank on a corrosion-resistant bracket, delivering constant volume at sustained load and preventing fuel starvation under high cornering or hard acceleration. This arrangement isolates pump noise and heat from the fuel supply, maintaining stable pressure throughout long runs and minimizing the risk of vapor formation.
LS Powertrain Integration
Designed to accommodate LS engine conversions, this tank features revised inlet and outlet positions that align with common hard line routes. The partnership with MuscleRods ensures that fuel line attachments and electrical connections correspond with their engine mount layout, which preserves proper engine placement and driveline angles. This coordinated approach streamlines the swap process, guaranteeing that fuel delivery components work in harmony with the V8 powertrain geometry established by leading conversion specialists.
Durable Fabrication and Easy Assembly
Constructed from premium gauge steel and finished with a corrosion-resistant coating, the tank resists rust and endures the stresses of repeated filling cycles. Internal baffling keeps fuel in position during braking and acceleration, while a full sealing flange prevents leaks at the sending unit interface. DIY-friendly installation requires no additional components-mounting straps and hardware are included, along with a plug-and-play wiring harness and step-by-step instructions-so enthusiasts can complete the job without specialty tools or aftermarket adapters.
This 255 LPH pump kit delivers dependable EFI flow for LS swaps up to 550 hp and for applications over 550 hp consider our 1968 Impala EFI Fuel Tank kit - 400 LPH Pump which is the same but with the larger 400 LPH pump.
