Notched EFI Fuel Tank Kit for LS and LT Swaps on 1971-1972 Buick Skylark
For Skylark models from 1971 through 1972 undergoing an LS or LT engine swap, this kit gives you the clearance and fuel flow reliability required for high demand powerplants. Featuring a 400 LPH Walbro pump inside the tank, it delivers a consistent supply even in supercharged or high output setups. A notched tank profile keeps exhaust pipes and rear tires clear, while the in tank design simplifies the install and reduces extra hardware needs. An integrated fuel level sensor provides precise readings so unexpected fuel drops become a concern of the past.
Notched Tank Profile Enhances Exhaust and Tire Clearance
The unique notched shape of this fuel tank is engineered to clear exhaust pipes and rear tires on a 1971-1972 Skylark chassis without any modification to factory sheetmetal. By moving material away from critical interference zones, the design preserves ground clearance and allows full suspension travel. This careful profiling eliminates the need to reroute or trim exhaust components, maintaining the vehicle's integrity and silhouette. Owners benefit from a hassle-free fit that respects the original body lines even when swapping in LS or LT powerplants.
400 LPH Walbro Pump Ensures Steady Supply for 550 Plus HP Setups
At the heart of this kit sits a high-capacity Walbro pump capable of delivering 400 liters per hour, even under the demands of supercharged or 550 plus horsepower engines. Its proven internal rotor and stator design provides consistent flow at elevated boost pressures, minimizing the risk of fuel starvation during hard acceleration. Locating the pump inside the tank helps keep it cool and reduces cavitation, so performance remains reliable across varied driving conditions. This robust delivery system gives tuners the confidence to push output without worrying about the fuel supply.
Integrated In Tank Design Reduces Installation Time and Leak Points
By housing both the pump and sending unit inside the tank, this solution streamlines the entire fuel delivery setup. There are fewer hoses and fittings running along the frame rails, cutting down on installation steps and potential leak paths. The kit arrives with all necessary tank straps, filler neck pieces, gaskets and mounting hardware to bolt directly to the chassis. Clear instructions guide users of all skill levels, transforming what can be a complex upgrade into a straightforward swap.
Precise Fuel Level Monitoring for Reliable Road Performance
An accurate sending unit built into the tank module ensures that your dash gauge reflects the true fuel volume at all times. Its stable float mechanism maintains consistency during cornering, braking and acceleration, so sudden dips in fuel pressure become a thing of the past. This precision monitoring lets drivers plan refueling stops without guesswork and prevents unexpected lean conditions on spirited drives. The result is confidence and uninterrupted performance on every journey.
