OEM Fat Boy Gas Tank Options

For riders who want an original factory-style replacement, an OEM Harley-Davidson Fat Boy gas tank is often the preferred option.

Before purchasing a Fatboy gas tank, compare the tank’s application with your motorcycle’s:

• Model year
• Exact model designation
• Fuel-injection or carbureted configuration
• Tank mounting points
• Fuel-pump configuration
• Fuel-cap style
• Dash or gauge configuration
• Tank capacity
• OEM part number

Fitment can vary substantially between generations. Some aftermarket tanks are specifically designed for certain Softail or Fat Boy applications, while other tanks are intended for custom builds or older Harley frames. Sportster rims

Fuel capacity depends on the Fat Boy generation and tank design. Harley-Davidson specifications for the 2016 Fat Boy FLSTF list a 5-gallon fuel capacity.

Aftermarket replacement and custom tanks can offer different capacities. For example, certain bobbed replacement tanks designed for M8 Softail applications are available in a 6.3-gallon configuration.

Because capacity and dimensions vary by application, always confirm the specifications for the exact tank you intend to purchase rather than assuming all Fat Boy tanks are interchangeable. 18×5.5 Fat King Spoke Black Rear Wheel Rim Cush Harley 2009^ Touring Bagger Glide

Why Buy a Replacement fatboy gas tank for sale?

A replacement tank can make sense when your original fuel tank has:

• Dents or collision damage
• Rust or internal corrosion
• Damaged mounting points
• Paint damage
• Fuel-system compatibility issues
• Excessive wear from years of use
• Damage that makes professional repair uneconomical

For restoration projects, an OEM or OEM-style tank can also help maintain the classic appearance associated with the Fat Boy.

Painted vs. Unfinished Fatboy Gas Tanks

When shopping for a Fatboy gas tank for sale, pay attention to the finish.

A painted tank can be convenient when you want a tank that is ready to complement your motorcycle’s existing color scheme. An unfinished or raw-steel tank may be better for a custom build because it gives you the freedom to choose your own paint, graphics, or finish.

Some aftermarket tanks are specifically sold unpainted and require preparation before installation and painting. Manufacturers and retailers recommend fitting and pressure-testing tanks before applying the final finish. Fishtails Chrome Exhaust Pipes For Harley

How to Choose the Right Fatboy Gas Tank

The best way to find the correct replacement is to match the tank to your motorcycle before purchasing.

1. Identify Your Model Year

Start with the year of your Harley-Davidson Fat Boy. Tank designs can change between generations, making year-specific fitment especially important.

2. Confirm the Model

Check whether you have a Fat Boy, Fat Boy 114, or another Softail model. Similar-looking Harley-Davidson motorcycles may use different fuel tanks.

3. Check Fuel-System Configuration

Older carbureted motorcycles and later fuel-injected motorcycles can require different tank configurations. Never assume that a tank designed for a carbureted model will work with a fuel-injected motorcycle.

4. Verify the Part Number

If you’re replacing an OEM tank, compare the original Harley-Davidson part number with the replacement listing whenever possible.

5. Check the Finish

Choose between factory-painted, primed, raw, or custom-ready finishes depending on your project.
