Frequently Asked Questions

Will this fit my Sportster?

Yes — fits all Sportster models 1979-2003. Verify year for correct gas cap style (cam vs. screw-style bung).

Does this come ready to install?

No — the tank ships as raw steel and requires final prep, paint, and internal sealing before use. Gas cap sold separately.

What needs to happen before I can use this tank?

Test fit to your frame, then have it professionally sealed inside and painted outside. Internal sealing is critical for warranty coverage.

Will warranty cover my tank if I skip sealing?

No — warranty does not cover tanks that are not pressure tested and properly sealed internally. Sealing is mandatory.

Why is sealing so important?

Unsealed steel tanks rust from the inside out, contaminating fuel and potentially damaging carburetors or fuel injectors. Sealing prevents rust and extends tank life.
