1968-1969 Chevy Chevelle LS Swap EFI Fuel Tank Kit with 255 LPH Pump
When converting a 1968-1969 Chevy Chevelle to LS injection you need a tank that matches modern EFI requirements and this 255 LPH pump kit provides exactly that solution. Engineered to bolt into the original frame mounts on A Body Chevelles the assembly houses a Walbro pump inside the tank to reduce heat soak and maintain steady pressure under sustained load. By integrating factory level sensors and precision gaskets it preserves dashboard gauge accuracy without custom adapters. Installers will appreciate the USA made materials and detailed instructions that simplify every step.
Internal Pump Positioning for Consistent LS Fuel Delivery
By situating the 255 LPH Walbro pump entirely inside the tank, fuel temperature remains lower than with an external assembly, reducing the risk of vapor lock under hard acceleration. This placement also minimizes turbulence so the pump draws a steady supply even when the tank is low. Rated to support engines up to 550 horsepower, this design ensures stable pressure to the LS fuel rail and prevents lean spikes. The internal flow path is tuned to avoid dead spots and extend service life. Access to the module is simplified by a removable ring that allows replacement of wear items without removing the entire tank.
Precision Fitment for 1968 to 1969 A Body Chevelle Frames
The tank kit aligns with original frame mounting points so no cutting or welding is required. Its sending unit matches the factory gauge and wiring harness preserving dashboard function without adapters. All straps and hardware fit existing chassis holes and precut gaskets seal the filler neck and module opening. Detailed diagrams guide bracket positioning and vent filter routing for correct connection to fuel lines and vapor management. Specified torque values and clearances help installers achieve proper sealing while avoiding interference with exhaust or suspension components.
Premium Materials and USA Assembly for Lasting Reliability
Every component is chosen for corrosion resistance and mechanical strength to withstand harsh road and track conditions. Heavy gauge steel straps receive a durable powder coat finish that resists salt and moisture. Precision molded gaskets prevent leaks under pressure and temperature changes. A vent filter blocks contaminants to protect pump and injectors during extended service intervals. Assembly takes place under strict quality control in the USA ensuring consistent weld integrity and final inspection for every unit.
All in One Kit Streamlines LS Fuel System Installation
This comprehensive package includes the pump module, sending unit, filler neck, vent filter, gaskets and mounting hardware so no parts need separate sourcing. Matched components eliminate misfit issues that can lead to leaks or performance loss. Tank straps and gaskets are pre sized for a simple installation using basic hand tools. The design accommodates most LS engine variants and leaves room for harness routing and fuel line connections. As a result installers can complete the system quickly with confidence and reliability.
