High-Flow 255 LPH EFI Fuel Tank for 1968-1970 Pontiac A-Body

High strength steel construction provides an exact fit on 1968-1970 GTO and Lemans A-Body chassis, while the notched design and 255 LPH Walbro pump deliver consistent fuel flow up to 550 hp for LS engine conversions without risk of starvation. Direct-fit installation streamlines mounting and ensures precise exhaust and tire clearance so you can dial in peak performance.

LS Swap EFI Fuel Tank Kit for 1968-1970 GTO and Lemans

When upgrading a 1968 to 1970 GTO or Lemans with an LS engine swap, this EFI fuel tank kit solves chassis clearance challenges and sustains consistent flow under load. Designed with a precise notch to clear exhaust headers and tire travel, it aligns with factory mounts on A Body chassis for a direct install. The internal 255 LPH pump maintains steady pressure during hard acceleration to prevent fuel starvation. Backed to support up to 550 horsepower, this assembly streamlines installation and removes common fuel delivery concerns.

Notched Tank Geometry for Exhaust and Suspension Clearance

The specially formed tank body features a recessed notch that preserves critical space for both exhaust routing and rear wheel movement. By carving a precise pocket into the lower shell, this design eliminates the need for custom trimming and guards against contact with header pipes during sharp cornering. Heat and vibration from the exhaust are directed away from the tank wall, helping to protect weld seams and prevent material fatigue over time. Builders can keep factory exhaust paths intact while upgrading to EFI, reducing installation guesswork and preserving chassis integrity.

Integrated Pump Module for Aeration Prevention

Housing the 255 liter per hour fuel pump entirely inside the tank ensures gentle fuel draw and minimizes air ingestion under heavy acceleration. This in-tank placement keeps the unit submerged at all times, reducing the risk of cavitation even during spirited driving or hard launches. As a result, the system maintains stable pressure across the entire rev range and supports builds up to 550 horsepower without fuel starvation. Combined with a calibrated sending unit and precision gaskets, the module delivers reliable operation and accurate fuel level readings.

Precision Mounting Tailored to A Body Chassis

Every component in this kit aligns with original A Body mounting points on 1968 to 1970 GTO and Lemans models, providing a truly direct fit. The filler neck seats perfectly in the stock opening, and the included straps and hardware secure the tank without any frame modification. Vent filters and a factory-style sending unit remove the need for aftermarket adapters or custom brackets, keeping electrical connections simple. Whether tackling a first LS swap or refining a seasoned build, this assembly streamlines installation and keeps projects on schedule.
