Harley-Davidson Gas Tanks

Replacement Harley Gas Tank FAQ's

Yes. A larger aftermarket tank is a popular upgrade, especially for Sportster riders tired of hunting for gas every 100 miles while their friends on baggers keep rolling. Make sure the tank matches your frame and fuel system. Fuel-injected bikes need a tank built for an in-tank fuel pump.

What’s the difference between carbureted and fuel-injected Harley gas tanks?

Fuel-injected Harleys typically use an in-tank fuel pump, while carbureted models generally use a petcock or fuel valve. That means the tanks can differ in their pump openings, fuel connections, venting, and other fittings. They aren’t automatically interchangeable, so check your bike’s exact model and year before buying a replacement.

Do aftermarket Harley gas tanks come painted?

Many aftermarket Harley gas tanks come unfinished, in raw steel, or with a primer or protective coating rather than a finished paint job. That gives you a blank canvas for custom paint or a color match to your bike. Before painting, test-fit the tank and pressure-test it for leaks. Consider an appropriate tank sealer if the manufacturer recommends one. Finding a pinhole after the clearcoat is a special kind of heartbreak.

Do I need a new gas cap, petcock or fuel lines with a new tank?

Often, yes. Depending on your tank and bike, you might need a different cap, petcock, fuel lines, mounting hardware or a dash relocation for touring models. Check the listing for what’s included, and plan for the small stuff so you’re not stuck with a beautiful tank you can’t install.
