1968-1969 Chevy Chevelle A-Body EFI Fuel Tank Kit for LS and LT Swaps
When fitting an LS or LT engine into a 1968 and 1969 Chevelle A Body chassis the factory tank cannot meet the demands of modern fuel injection. This Chevelle EFI Fuel Tank Kit features a 400 LPH pump integrated with the sending unit and filler neck in a sealed module that bolts to the original crossmembers with no cutting or welding. Precision molded baffles manage fuel under cornering forces and braking changes while the American made assembly delivers a stable supply for engines that exceed 550 horsepower in both street and track environments.
Precision Direct Fit Design for 1968 and 1969 Chevelle A-body
The tank module bolts directly to factory crossmembers of a 1968 and 1969 Chevelle A-body without any cutting or welding, saving hours on fabrication and preserving original chassis geometry. By matching the shell contours and strap locations of the stock tank, it maintains underbody clearance and protects frame rails from unintended stress. All required straps, gaskets and mounting hardware are supplied, so installers with basic hand tools can complete the job without fabricating adapters or brackets. Retaining factory mounting points also safeguards suspension alignment and prevents interference with exhaust components. This precise fitment approach ensures installation consistency across street and track applications while upholding the vehicle’s classic profile.
All In One Tank Module Simplifies Assembly and Service
This EFI fuel tank kit consolidates the 400 LPH pump, sending unit, filler neck and vent filter into a single preassembled module, dramatically reducing part count and simplifying underbody routing. Factory sealed gaskets and precision machined sealing surfaces minimize potential leak sites, allowing builders to focus on fuel line and wiring connections rather than troubleshooting fitment issues. The integrated design aligns directly with original fuel hoses, eliminating custom adapters and ensuring proper venting for modern EFI systems. A clean undercarriage profile not only improves airflow under the car but also simplifies access for future maintenance or replacement. Installers benefit from a neater workspace and a professional-grade result that meets both street driveability and track demands.
400 LPH Pump With Baffles for Reliable Fuel Supply
At the heart of this module is a 400 LPH Walbro pump engineered for engines above 550 horsepower, including supercharged and turbocharged LS and LT combos. Its robust flow rate prevents fuel starvation during hard acceleration and sustained high load driving, while strategic internal baffles control fuel movement under cornering forces and braking transitions. These molded baffling chambers keep the inlet submerged as lateral loads shift fuel away from the pick up, avoiding momentary pressure drops that can trigger lean-condition stalls. Built in the USA to resist vapor lock and withstand demanding thermal environments, the pump and baffle system delivers a stable supply of fuel for both spirited street cruises and competitive track events. The result is unwavering EFI performance with accurate fuel pressure for precise engine management.
