[Zmagnette] Fuel tank sealer-Not entirely OT

[Gene deRuelle]

Be very careful what you use these days.  No too long ago I used some tank sealer in the fuel tank of my little airplane.  About a year later I suffered engine stoppage.  No real harm done on the forced landing except when I examined the fuel I found little green balls of stuff that had completely blocked the fuel lines.  It turns out that the additives that the manufacturers are putting in fuel these days, including Ethenol, are prone to dissolve the tank sealers which were never formulated for exposure to that junk.  I spent a month or so cleaning out the system on the plane and steaming out the tanks.  Now I just run bare metal

  It's the fuel tank on my Triumph motorbike, but I think it can be applied to our cars. Anyhoo, I just welded up a leaky seam on the tank. There was a little surface rust inside from all the soap and water rinses I've been running through it, so I decided to clean the rust out, which I did with a slurry of kerosene, ATF, and a couple of handfuls of roofing nails. After an hour and a quarter of agitation the rust is gone and things are looking good.

   

  So, I decided I would like to use a tank sealant, but not having any experience with any of the brands, or types, I'm wondering if anyone can make suggestions or recommendations based on products they have used.

   

  I think some of you have sealed or lined Magnette tanks. I would sure appreciate any tips.

   

  Thanks,

   

  David
