Syd and the group. As you know, I have been a proponent of keeping the header tank in place, argueing that it is safer to have a system that keeps the engine runnning than a system dependent on pumps that might fail and cause the engine to quit.....BUT.....
I see a lot of comments about using "weld" glues on leaking tanks.....and that scares me. If the tank wall is so thin that corrosion is eating thru and causing a leak, that leak may be stopped by the use of one of these JB Welds, etc., materials....BUT...if the skin is corroded and thin, then it will probably rupture in a hard landing, minor accident, etc., ie: a condition where an airworthy tank would not fail... So folks, be careful, if your header tank is bad, replace it!....or have it rebuilt properly, by replacement of the metal by soldering, welding, etc....approved repair process, so that it is strong enough to sustain a jolt. I am concerned that there may be those of us flying with non-leaking tanks, but that have corroded through tank bottoms that have been repaired with brittle materials, that would fail in an otherwise minor incident...... Yes it would be nice to have one of the new type material tanks available for replacement. The Auto racing world is using such a tank - Shame on Univair for not exploring the issue of an economical replacement composite tank. Maybe they can be encouraged to do so. Call or write them.... <A HREF="http://www.univair.com/";>Univair Home</A> Leaking gasoline is not a matter to be taken lightly.. Regards, Fly Safe - Have Fun Harry Francis 93530 Blacksburg, VA.
