Removing rust from the inside of a motorcycle gas tank using the electrolysis method?

Which is better for removing rust from the inside of a motorcycle gas tank using the electrolysis method? Steel anode or carbon graphite anode? I have tried both. I like the carbon graphite better. It seems to be a cleaner process and to work just as good as the steel anode. Should I use 12 volts or 3 volts? Does a pulsating DC work better than a continuous DC? What is the best amperage?

Amperage is all you need to control - apply the "right" voltage for those amps to flow.

This is the best reference I know of on the topic

Something like a gas tank inside will have a huge surface area, and you'll probably need substantial currents.

Are you intending to run the POR-15 kit around the inside afterwards, in case it pin-holes ?

This is very helpful. The power supply will be my next project.

Here's a link to a page with specific details to several methods for removing rust from a gas tank. The electrolysis method is about halfway down the page.
