Hi Dean,
Haven't heard from you lately. I really enjoyed talking with you at =
Oshkosh.
Did you find and fix your fuel tank leaks?

Subject: REFLECTOR:fuel tank leak testing
I'm still having difficulty finding and eliminating my fuel tank =
leaks. Let me review what I have done.
My two small bulkheads between the large rear bulkhead and the main =
spar have already been installed, but I can get my hand through the =
opening.
I reduce the pressure on my air tank/pump to a few psi (so I can =
easily stop the flow with my finger) so as to not damage the tank. I =
can hear the air escaping from behind the large bulkhead. When I first =
began working on it, I could feel air coming from that area just by =
reaching my hand in there. I have used a soapy solution, but cannot see =
any bubbles. I have used this technique with tires before with good =
results. However, the pressure in those cases were over 30psi.
I then tried using the tubing as some of you suggested. The sound is =
not localized and seems to be very steady all along the rear bulkhead.
I have applied sealant all along the seam using a paint brush attached =
to a pair of sticks so that I can adjust the paint brush after getting =
it through the small bulkheads.
It is hard to tell without quantitative measurement, but I think it is =
improving some.
I also tried to spray epoxy in the cavity using a water sprayer. The =
epoxy and cabasil were too think to really spray.
Any help would be appreciated.
