To line or not to line the fuel tank

I have quite a bit of rust in my gas tank. After I remove the rust, should I line the tank? I would use the POR product. Thanks for your opinions.

POR makes damned good stuff! I have been restoring antique machinery for many years and coat the tanks as a matter of course.

I hate the stuff but sometimes it's the last resort. I did an XL250 tank with the POR kit last year and needed some extra de-rusting fluid to properly get rid of the rust. I found that toilet-bowl cleaner worked better than the stuff that came with the kit.

There is a write up on electrolysis on this site. I started by filling the tank with aircraft stripper, BBs and small nuts. With a good sealing cap you can swish it around and break free any crud. I wouldn't shake though, might dent. After a few rounds of that (prob 30+ min of swish time) I followed the electrolysis procedure which takes several days. The tank was pretty bad to start and its perfectly clean metal afterwards. Did this to both my tanks with great success.

With one of my tanks I filled it up Wih de-rusting solution, bolts and other bits then wrapped it up tightly in foam and put it my cement mixer...

Saves all that tiring shaking and swishing..... :-)

Vote number 2 for electrolysis method. Worked very well for me but it is time consuming. The bad thing about the sealers is if they fail you have more of a mess than rust to deal with and a virtually unusable tank. I have not used any of the sealers but after the research I decided against it.
