1970 Buick Skylark Notched EFI Fuel Tank Kit with 255 LPH Pump for LS Swap
For builders installing an LS drivetrain into a 1970 Buick Skylark A Body chassis, the 1970 Skylark EFI Fuel Tank Kit with 255 LPH Pump Notched matches tight underbody clearance requirements with precision notched shell contours that avoid exhaust and tire interference while preserving suspension travel. The kit includes an internal fuel pump module and a fuel-sending unit rated at 255 LPH for support up to 550 horsepower, plus filler neck, vent filter, gaskets, tank straps and mounting hardware. A corrosion resistant steel tank with punched mounting points simplifies installation and eliminates fitment challenges, and an optional 400 LPH pump upgrade is supported for setups exceeding 550 horsepower.
Consistent Fuel Delivery
The 1970 Skylark EFI fuel tank kit relies on a high-flow Walbro pump rated at 255 liters per hour to maintain precise supply under heavy demand. By supporting engine outputs up to 550 horsepower, it alleviates pressure drop at sustained high rpm. This steady volume delivery prevents lean spots that can impair performance, smoothing throttle response across the entire powerband without risk of cavitation or sudden drop off. Technicians will appreciate that onboard filtration ensures debris is caught before it reaches the rail, preserving injector life.
Precision Clearance Design
Tailored specifically for a 1970 Skylark frame with an LS swap, the shell features driver-side notches that create dedicated clearance for modern exhaust headers and full-lock rear tire sweep. By removing material only where interference would occur with tube header collectors or the rotating rubber, the kit preserves maximum capacity and structural integrity. Each contour aligns with factory crossmember rails and suspension lines to guarantee a perfect match with minimal trimming or rework required.
Heavy Gauge Construction and Baffling
Fabricated from heavy gauge steel and finished inside with a corrosion-resistant coating, this assembly integrates an internal baffling network to limit fuel movement during acceleration, braking and cornering. A threaded fill neck with a secure cap and dual vent ports streamlines refueling operations and prevents pressure buildup under heat. The robust shell resists deformation under road impact and shields the pump assembly from debris, ensuring reliable service under demanding conditions.
Seamless MuscleRods Integration
This kit is engineered to interface directly with MuscleRods engine mounts by matching crossmember mounting points and locating tabs. That collaboration ensures proper engine placement ahead of the rear axle and preserves precise drivetrain angles for both transmission output and driveshaft pinion. All required mounting hardware is included along with step-by-step instructions, delivering a straightforward installation on chassis built to MuscleRods specifications and guaranteeing factory-caliber alignment.
