1968-1969 Chevy Chevelle EFI Fuel Tank Kit with 255 LPH Pump for LS Swaps
Whether you are converting your classic A Body Chevelle for street or track use this 1968-1969 Chevelle EFI Fuel Tank Kit addresses the precise fuel requirements of a modern LS system with a 255 LPH pump housed in a custom tank. Crafted to fit the original frame mount points and factory level sensors the assembly streamlines installation and eliminates fitment headaches. By positioning the pump inside the tank heat exposure and fuel turbulence are reduced to maintain stable pressure under sustained high rpm. With rugged materials and exact gaskets the kit supports up to 550 horsepower and ensures consistent delivery for any LS swap scenario.
Internal Pump Positioning for Consistent Fuel Pressure
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 internal placement also minimizes turbulence in the fuel line, so the pump draws a steady supply even when fuel levels run low during spirited driving. With a design rated for up to 550 horsepower output, the pump maintains stable pressure to the LS fuel rail, protecting injectors from starvation and preventing lean spikes. Engineers calculated the internal flow path to reduce dead spots, ensuring the pump operates within its optimal range and extends service life. The reduced exposure to engine bay heat and road debris supports sustained track sessions without performance fade. Maintenance access to the internal module is simplified by a removable ring, letting technicians replace wear items without dropping the entire tank.
Precision Chassis Fitment for 1968 to 1969 A Body Chevelle
Every component of this tank kit aligns precisely with the frame mounting points on a 1968 to 1969 A Body Chevelle, requiring no cutting or welding of the original structure. The tank's sending unit is designed to interface with the factory gauge and wiring harness, preserving the classic dashboard functionality without custom adapters. Mounting straps and hardware drop into existing chassis holes, and all gaskets are pre sized to seal the filler neck and pump module without trial fit steps. Comprehensive diagrams and instructions guide installers through bracket positioning and vent filter routing for correct placement relative to fuel lines and vapor management. The kit also leaves clearance for most exhaust and suspension setups common to LS captures, reducing the risk of interference with downstream components. Detailed torque values and sealing surface call-outs help both seasoned builders and home enthusiasts complete the installation with confidence.
Premium Materials and USA Assembly Ensuring Reliability
The fuel tank and its associated parts are manufactured from materials chosen for corrosion resistance and mechanical strength, safeguarding against degradation in harsh environments. Heavy gauge steel straps are powder coated for added protection, locking the tank securely against road salt and moisture exposure. Precision molded gaskets seal the filler neck and module opening to prevent leaks under pressure and temperature variations. A vent filter keeps contaminants out of the system, preserving pump and injector life through extended service intervals. All components are assembled in the USA under strict quality control, so each unit meets consistent standards from weld integrity to final inspection. This level of craftsmanship ensures durability and peace of mind for daily driving as well as weekend track use.
Comprehensive Kit Design Simplifies LS Fuel System Setup
This all in one solution delivers the pump module, sending unit, filler neck, vent filter, gaskets and mounting hardware in a single package, avoiding the need to source parts separately. Each gasket and seal is matched to interface with the Chevelle chassis and LS injection system, eliminating misfit issues that can lead to leaks or loss of output. The included tank straps and precise layering of components allow installers to assemble and secure the system with basic hand tools in minimal time. By bundling critical items into one kit, fuel system planning becomes straightforward, reducing project complexity and unexpected downtime. Installers benefit from a cohesive design that accommodates most LS engine variants without part swaps or adapter kits. The result is a fast, reliable setup that delivers cool, pressurized fuel for every driving condition. The kit's layout also leaves space for wiring harness routing and fuel line connections, so secondary system setup integrates seamlessly.
