1968-1969 Chevy Chevelle EFI Fuel Tank Kit for LS and LT Swaps
When fitting an LS or LT engine into a 1968 to 1969 Chevy Chevelle A body, installers often confront clearance conflicts between the stock fuel tank and frame rails, exhaust tubes or sensor bosses. The 1968-1969 Chevelle EFI Fuel Tank Kit features a notched tank and a 400 LPH in-tank pump rated for supercharged or 550+ horsepower applications to maintain clearance for exhaust pipes, tires, fuel lines and sensor mounts without trimming. Its steel shell houses the pump module and includes a sending unit, filler neck, vent filter, straps, gaskets and all installation hardware, delivering steady flow under demanding loads.
Precision Cut Clearance
The notched tank design provides targeted relief around exhaust headers, rear tires, fuel lines and level sensors. By removing precise sections from the container sidewalls, the kit avoids any contact that could lead to vibration wear or heat soak. This attention to detail preserves ground clearance and maintains optimal fuel tank position relative to the frame rails. Each notch location has been laser cut to engineered tolerances, ensuring that the tank sits true and centered under the cargo floor. This layout delivers peace of mind by eliminating the need for ad hoc modifications during final assembly.
Robust Fuel Delivery
At the heart of this assembly is a 400 LPH pump module capable of meeting surge demands from boosted powerplants or naturally aspirated builds exceeding 550 horsepower. The in-tank pump assembly keeps the unit submerged at all times, preventing cavitation under hard acceleration and cornering. The result is rock-steady fuel pressure that supports EFI tuning maps without dropping below target values. This level of reliability is critical for any serious engine swap where precision calibration drives performance.
Seamless Integration and Installation
This kit is fully compatible with LS and LT engine conversions in second generation Chevelles. MuscleRods engineering ensures that mounting points line up flawlessly with their frame brackets, maintaining correct driveline angles and firewall clearance. All installation hardware is included to deliver a complete solution right out of the crate. Installers benefit from a streamlined process that removes guesswork and eliminates parts gathering. Every component has been rigorously tested by MuscleRods to meet demanding durability standards expected in daily drivers and road-race applications alike.
