Feuerhand leak (and what I did) Technical Assistance

Okay, first off there aren't any pics here but none should really be necessary.  I recently found a well used Feuerhand 275 Baby and took it home.  After a brief checkout I fueled it up and lit it and everything was fine.  After a few hours though I noticed a ring of kerosene around the base and knew there was some trouble.  So I just let it burn itself dry and when I took the fuel cap off imagine my surprise to find SPRAY FOAM! Yeah that's right, spray foam.  I did look in the tank before I bought it but the foam was back in there a ways and I probably should have looked closer.  Anyhow before I can do anything the foam has got to come out.  I tried several different solvents and thinners but they didn't faze it.  Then I tried some furniture stripper and that worked a lot better although it was not 100% and attempts to rattle nuts and scour the inside were futile.  I wanted to pour some epoxy into the tank but I was afraid that the residual foam wouldn't let it flow around so I inverted the lamp and coated the base almost level with clear 2K epoxy (there were numerous holes that were too big to try and solder) and let that dry.  Then to seal the inside I mixed up a small amount of DuPont epoxy primer and sloshed that around inside to coat the tank and let the rest dry in the bottom.  I'm doing some body work on a 66 C10 so I've got some things on hand that might not be practical for a lot of people but if you're familiar with epoxy primer you know that it's some crazy sticky stuff that resists almost everything.  I admit that I haven't had a chance to light it yet but the primer should go a long ways to stopping any further corrosion and I don't see how it could possibly leak right now.  And that makes me wonder if there is a down side to coating the inside of all my wikkies with epoxy primer.  If it seals the inside from corrosion and fills in any potential seam leaks it might be a good idea.  I will try this out for a while before I draw any real conclusions. Thought, questions, comments?

I don't know about removing the foam, but found that using a little varnish will stop weeping.  A wickie is under no pressure so this works well.
Below is from the FAQ at lanternnet.com.  See the NOTE: below the ANSWER: paragraph.


QUESTION 9:   How do I stop a tubular lantern from leaking from the tank?

(NOTE:  Take all safety precautions, use gloves, safety glasses, etc.)

ANSWER:  Remove the burner and fuel cap, and empty the oil completely.  If the inside of the tank is rusted and full of crud, drop a 1' piece of "Sash" chain into the tank and pour in one cup of white vinegar.  Swish the vinegar and chain around to knock down the heaviest rust or crud.  Drain the tank, and allow to dry in the sun, or use a blow dryer on low to completely evaporate all of the vinegar.   Remove the chain and make sure that there is nothing left in the tank like a piece of wick.  If there are visible holes in the tank, use masking tape to cover them.   Put on a pair of disposable gloves, then use a funnel to carefully pour into the tank about 2 teaspoons of  U.S. Standard "POR-15" Gas Tank Sealer to coat the entire inside.  Rotate the lantern to thoroughly coat both the bottom and sides of the inside of the tank.  If you get any sealer on the fuel spout or burner cup be sure to clean it off.  After the sealer cures in a few days, another coat of sealer can be added if the condition of the tank warrants it.  Let the lantern cure for one week, remove the masking tape and put the lantern back into service.  This method of re-sealing will usually last the life of the lantern.

NOTE:  If the lantern leaks only from the crimp at the bottom edge, exterior grade marine spar varnish can be used to seal a weeping tank.  Use 1 to 2 teaspoons and allow to dry for one week before refilling with oil.

I've heard of using POR15 but didn't know how well it would work over the foam. That stuff didn't want to come out. A really stupid way to try and fix a leaky lantern. The primer and epoxy was already on hand. 

Good advice in that link. Thanks
