Notched EFI Fuel Tank Kit with 255 LPH Pump for LS Swap 1970-1972 Chevy Chevelle
When installing an LS engine in a 1970 to 1972 Chevelle A Body the original fuel tank often interferes with exhaust pipes and suspension travel so this notched tank kit reshapes the lower shell for precise clearance while integrating a 255 LPH pump capable of supporting up to 550 horsepower. Fabricated from heavy gauge steel with corrosion protection the tank resists chassis flex and road debris and the precision welds deliver a leak free assembly suitable for street and track driving. Installation uses factory frame rail mounts, original suspension brackets, and included straps and gaskets to secure the tank without custom adapters. Consistent volume under sustained high rpm maintains steady pressure and smooth throttle response.
Precision Notched Geometry for Exhaust and Suspension Clearance
The notched lower shell is shaped to match the contours under the rear of a 1970 to 1972 Chevelle A Body, creating vital room for both exhaust pipes and full suspension travel. This tailored geometry prevents contact with rear axle tubes and mufflers, avoiding costly damage and noise. By preserving clearance for shock mounts and leaf springs, the design maintains factory ride height and handling balance under load. Builders benefit from a clean fit that follows original floor pan curves, requiring only minimal trimming of tubs. The result is a secure installation that upholds chassis integrity and reliable cornering response.
Steady Fuel Flow from 255 LPH In Tank Pump
Equipped with a Walbro pump rated at 255 liters per hour, the in tank module supplies consistent volume for LS engines up to 550 horsepower without risk of starvation. Internal placement limits exposure to heat soak, keeping fuel temperature stable during sustained high rpm. This consistent pressure prevents air ingestion and lean conditions that can lead to detonation or component wear. Drivers experience smooth throttle response and steady performance whether on winding backroads or the racetrack. The modular pump module also simplifies service access and future capacity upgrades.
Heavy Gauge Steel Fabrication with Corrosion Protection
Formed from heavy gauge steel and treated with a corrosion resistant finish, the tank resists road salt, moisture, and debris strikes that can deform lighter units. Precision weld seams are fully penetrated to deliver a leak proof shell that endures chassis flex encountered during spirited driving. Reinforcements at stress points ensure the vessel maintains its shape over years of use, preventing bulge that could misalign the pump. Internal baffling at the inlet keeps fuel from sloshing away under hard acceleration or cornering, guaranteeing uninterrupted delivery in all conditions.
Factory Frame Rail Mount Installation with Included Hardware
This kit leverages original frame rail mounts and suspension brackets for a true bolt in installation, eliminating the need for chassis cutting or welding. Comprehensive hardware-tank straps, gaskets, filler neck, vent filter, and mounting bolts-mates precisely with factory fuel lines and plumbing. The integrated sending unit fits directly into the new flange to provide accurate level readings without splicing or harness changes. Clear instructions and matched components let builders focus on engine tuning rather than adapter fabrication, delivering reliable operation from the very first start.
