The Foundation of Fuel: High-Performance Fuel Tanks for Pontiacs at Butler Performance

1. The EFI-Ready Solution: Fuel Starvation Prevention

The greatest challenge when converting a classic car to EFI is ensuring the high-pressure fuel pump is always submerged in fuel, even under hard acceleration or cornering.

• In-Tank Design: Butler Performance heavily features EFI Ready Fuel Tanks (often from Tanks Inc. or Holley Sniper) designed for a direct fit into the chassis of classic Pontiacs ($1964\text{-}1972\text{ GTOs}$ and $1967\text{-}1981\text{ Firebirds}$).

   
   

• Internal Baffling: These tanks feature advanced internal baffling, including a large internal fuel tray (or reservoir). This reservoir ensures the in-tank fuel pump remains covered in fuel, preventing the dangerous and performance-robbing condition known as fuel starvation, which can be catastrophic to high-output EFI systems.

   
   

• Integrated Fuel Pumps: The EFI-Ready tanks are available with or without a fuel pump and sending unit, allowing builders to choose their power level. Pump options often include high-flow modules (e.g., $255\text{ LPH or }400\text{ LPH}$ Walbro pumps) capable of supporting engines from $600\text{ hp}$ up to $1,000\text{ hp}$.

   
   

• Corrosion Resistance: The tanks are typically made from galvanized steel, then silver powder-coated for total corrosion resistance and durability.

   

2. Complete EFI Solution Kits

Recognizing that the fuel tank is just one piece of the EFI puzzle, Butler Performance offers master kits for the complete conversion:

• Butler Complete EFI Solution Kits: These bundles include an EFI system (such as Holley Sniper, FiTech, or FAST), and they are paired with a vehicle-specific EFI Ready Fuel Tank with the appropriate in-tank fuel system already installed. This "one-stop shop" solution simplifies the conversion process and guarantees component compatibility.

   

3. Stock Replacement Fuel Tanks

For restorers or builders retaining a carburetor who only need a reliable, clean replacement for a rusted factory unit, Butler Performance offers Stock Replacement Fuel Tanks.

• OEM Fit and Finish: These tanks are designed to match the original factory dimensions and mounting points, ensuring a hassle-free swap using existing straps and filler neck components.

4. Supporting Fuel System Components

The tanks are often supported by necessary accessories to complete the installation:

• Fuel Sending Units: Compatible sending units are offered to work with either factory gauges or aftermarket systems.

   

• Tank Straps: Replacement or longer heavy-duty tank straps are available for different chassis applications, ensuring the new tank is securely mounted.

   

• Fuel Pump Modules: High-flow, drop-in fuel pump modules are available separately to retrofit a stock fuel tank for EFI use, although the EFI-Ready baffled tank is the preferred method for performance.

By providing these engineered fuel containment and delivery solutions, Butler Performance ensures that every stage of a high-power Pontiac's fuel system—from the tank to the injector—is reliable, safe, and perfectly suited for modern performance demands.
