1971-1972 Buick Skylark EFI Fuel Tank Kit for LS and LT Swaps
When fitting an LS or LT engine into a 1971 through 1972 Skylark A Body chassis, clearance around exhaust pipes and fuel reliability become immediate concerns and this notched EFI fuel tank kit meets both needs. It uses a 400 LPH Walbro pump inside the tank to maintain consistent delivery for supercharged or over 550 hp applications while the notched design ensures rear tires and exhaust components stay clear. Integration of the pump and level sensor within the tank reduces external hoses and potential leak points for a cleaner installation. Precise fuel level readings during cornering and heavy braking help keep your setup safe and predictable on every drive.
Notched Tank Profile Enhances Exhaust and Tire Clearance
The notched shape of the tank is precisely formed to clear exhaust pipes and rear tires on a 1971 1972 Skylark chassis without altering factory sheet metal. By removing material at interference points the design preserves ground clearance and full suspension travel. This approach eliminates the need to reroute or trim exhaust components and maintains the vehicle silhouette. Owners gain a direct fit that respects original body lines even when installing LS or LT engines.
High Capacity 400 LPH Pump Performance
At the core of this kit is a Walbro pump rated at 400 liters per hour, built to handle supercharged or over 550 horsepower setups. Its internal rotor and stator design keeps fuel cool and reduces cavitation by operating inside the tank. Consistent delivery under boost prevents starvation during hard acceleration and supports stable engine operation. Tuners can confidently push output knowing the supply remains uninterrupted across varied driving conditions.
Streamlined Assembly with Integrated Pump and Sensor
Housing both the pump and sending unit inside the tank cuts down on hoses and fittings along the frame rails, which simplifies the installation process. The kit includes tank straps, filler neck, vent filter, gaskets and all necessary hardware for a direct bolt in to the chassis. With clear instructions, even those new to swaps can avoid common pitfalls and potential leak points. The result is a cleaner underbody layout and reduced install time.
Reliable Fuel Level Monitoring Under Dynamic Conditions
The built in sending unit features a stable float mechanism that delivers precise readings during cornering, braking and acceleration. This consistency removes guesswork and prevents unexpected lean conditions that could harm the engine or lead to a stall. Drivers can plan refills based on accurate gauge feedback and maintain uninterrupted performance on spirited runs. The system enhances safety and confidence on every drive.
