Fuel Tank Sealants

Fuel Tank Sealants

I found old messages on cleaning and coating fuel tanks but not much about
specific brands. Can someone tell me if they have tried the gas tank repair
kit from Eastwood?

The PO had brazed the bottom brass bolt to the tank. Should I try to free
it and replace it? In one of the notes, I saw that there is a filter under
the bolt? Since I have considerable rust inside the tank, is it possible
that the filter is clogged?

To all

In response to questions about fuel tank sealant products, I have had
excellent results with the POR15 tank sealant products (advertised in
Hemmings) on several of my non-Jag projects. Buy the whole kit and use it
as directed. The finish job will be terrific. I must mention, however, the
tanks I sealed did not have a lot of small holes or leaks. But, the
consistancy of the sealer (I think it is an air cure epoxy of some sort)
should seal most small holes etc.. This finished sealant is impervious to
any type of fuel or additive.

While I cannot remember the brand name,I had very good long term results
with a product I bought from a local aircraft repair service. I choose it
because it was approved for aircraft fuel tanks as well as being Mil-Spec

I used a service which is called Re-nu in Hemmings that reclaims the
gastank. No problems yet. Cheaper than buying a new tank.

My 150 has a large 1.5" disc looking thing with a hex fitting on it that
when removed would reveal a fine brass screen soldered into a cylindrical
shape the top of which had a hole which a fuel pickup tube would extend
into the screen thereby filtering the fuel from any water in the bottom of
the tank. I found the screen (you can get it in various sizes, 80 holes per
inch, 100 holes per inch and 120 holes per inch) at a local hardware store
where they would cut however much you needed from a 8 X 10 inch sheet of
the stuff. Then I just cut it to the size of the cylinder with a pair of
scissors and soldered it all together.
After all that I too used the POR 15 product advertised in Hemmings, and as
I recall I used the type that is impervious to alcohol in that
they sometimes put alcohol in the gas here whether you like it or not!!
Hope that helps.....
