I'm e-tanking the inside of my spare gas tank.  Any idea how long it should run, or is there a way to know when it is done? It had a moderate amount of rust with some pinholes. The pin holes where soldered prior to the e-tanking. The sacrificial offering is a bent clothes hanger.

I would let it run about 8 hrs and rinse it out to see how it looks. It more then likely will need to be re-run.

 

You may want to replace your anode every couple hours to keep a clean surface.

 

Do you have this setting in a tank submerged to keep the gas tank full?

Looks like he has the tank full of the solution and using the coat-hanger INSIDE of the gas tank.....The gas tank IS the E-tank.

I can see the bubbling out the top of the gas tank opening.

I see that,but he should have it in a bigger tank. It will let a lot of the debris float out and keep the gas tank full of solution.

I thought he was wanting to clean the inside of the tank, so why wouldn't this set-up work?

It will, but you push solution out of the tank an it foams up, so the level drops as you let it work. You can put in a bigger tank and not treat the outside, don't power the anodes in the big tank.

KC9KAS: As the tank runs, the liquid foams up from the bubbles.  That depletes the fluid in the tank. If it was submersed, the water would just run in from the outer tank as the foam floats out of the gas tank with the rust.  I just topped it up every hour, but that was a royal pain.  Next time, I'm going to put it in a tank like TD&H suggested.  That will also let me clean the outside at the same time.

 

I ran it for 6 hours & rinsed it.  Could have used a couple of more hours.  Likely 8 total, as TD&H suggested.  Anyway, I'm going to have it coated inside once it is painted.  They'll do a final rust removal before they coat it.  I was more interested in whether new pinholes would develop when it was cleaned.  Luckily, none appeared.  I've sprayed it with some Rust Check rust converter.  Tomorrow I'll fill some small dents & prime it.

Great to hear that you don't have to do any more repairs.

 

You can leave the solution in the tank and it won't rust until you get to finish it. I leave stuff in my tanks until I can find the time to clean them.

 

"Olcowhand" gave me that bit of info, Thanks Daniel ! :thumbs:
