Notched EFI Fuel Tank Kit with 400 LPH Pump for 1970 Buick Skylark LS/LT Swap
The 1970 Skylark EFI Fuel Tank Kit with 400 LPH Pump Notched addresses the need for reliable high volume fuel delivery and precise chassis integration when swapping LS or LT powerplants into an A Body. Its notched tank design clears exhaust piping and rear tires by mirroring factory floorpan contours, while the submerged 400 LPH Walbro pump and fine mesh sock filter sustain steady pressure for applications over 550 horsepower. Complete with in tank pump module, sending unit, filler neck, vent filter, gaskets, straps and installation hardware, this direct fit assembly for the 1970 Buick Skylark demands minimal modification to streamline installation and ensure proper component alignment.
Precision Fuel System Integration
The 1970 Skylark EFI Fuel Tank Kit with 400 LPH pump employs a notched tank design that clears aftermarket exhaust paths and wide tire setups, preventing interference under dynamic conditions. This tailored cutaway ensures full range of motion without sacrificing ground clearance. By working with MuscleRods mounting points, the assembly maintains optimal engine placement and correct drivetrain angles, delivering a precise interface between the fuel system and the chassis. This alignment minimizes stress on components and preserves factory geometry for reliable street and track performance.
Robust Pump Performance for Demanding Applications
The included 400 LPH Walbro pump is engineered to support forced induction or engines making over 550 horsepower, maintaining steady pressure during high RPM shifts and wide open throttle. Positioned inside the tank, the in-tank pump module is submerged for inherent cooling, reducing the risk of vapor lock under heavy loads. This configuration also allows the unit to draw directly from the lowest point, ensuring consistent pickup even during aggressive cornering. The robust design accommodates ethanol blends and modern fuels, providing builders with confidence in sustained delivery under varied driving conditions.
Simplified Installation Process
This comprehensive all-in-one kit arrives ready to install with preassembled components and wiring harnesses, allowing a straightforward swap into 1970 Skylark frames fitted with LS or LT engines. Mounting brackets match existing fastener locations, so only minimal trimming of seat pan or chassis rails is needed for final clearance adjustments. Detailed instructions guide installers through fuel line connections, electrical prep, and calibration checkpoints. By minimizing fabrication and welding, the kit reduces shop time and potential alignment errors, accelerating project completion with professional results.
Engineered Fitment for LS and LT Platforms
Developed specifically for GM's Gen IV small block architecture, the fuel tank kit aligns with LS and LT block patterns and accessory accessories. The form-fit shell conforms to factory dimensions while accommodating the notched sections, delivering a seamless appearance under the rear sheetmetal. All brackets, seals, and connectors are vehicle specific, guaranteeing secure attachment and leak-free operation. This direct-fit approach ensures the fuel system integrates smoothly into any Skylark restoration or custom build, providing a dependable foundation for high-output powertrains.
