Will this bolt directly onto my engine bay without drilling or modifications?

Yes. This tank mounts at the factory attachment points with no drilling or welding required. It's a straight swap for the OEM tank.

Do I need to transfer any fittings or hoses from my old tank?

Most likely. Check your current tank's hose and cap configuration before installation — you may reuse existing fittings depending on their condition.

Can I paint this tank to match my engine cover or leave it white?

The white finish is pre-applied and ready to install as-is. If you want a different color, light sanding and automotive paint will work, but it's not required for function.
