Frequently Asked Questions

Does this fit my 1985+ Harley or Softail?

No — this tank is designed for 4-Speed Big Twin frames only, and will not fit Softails or 1985+ models with different frame geometry.

What finish does the tank come in?

Raw unpainted metal. You must complete final prep work, sealing, and paint before installation.

Do I need to test and seal the tank before use?

Yes — all fuel tanks must be pressure tested and sealed inside before riding. Failure to do so voids the warranty.

Will my aftermarket fuel cap fit?

Yes — the tank accepts both OEM Harley caps and most aftermarket fuel valves and caps.

Can I use this with a custom frame?

Yes — it fits custom rigid and swing arm Big Twin frames, but test fit before any final prep work to ensure proper clearance and mounting.
