Sloshing Compound or drip?
Posted: Fri Feb 17, 2012 8:39 pm
I am slightly deflated. I have been working on my fuel tanks for some
time. Here is the situation:
1. Left wing holds 1-2 PSI for an hour or two, slowly running down. I
can't find the leak. I suspect it is under the skin somewhere that I
can't reach or see (yes my top and bottom skins are already in place).
It won't leak water. As far as I can tell I have 4 grim options: A -
Leave it alone and see if it develops a fuel stain during the first 6
months or so of flying. B - Find a sloshing compound that can handle
Auto and Aviation fuel without working loose and plugging the outlet. C
- Take the top wing skin clear off (drilling out the main spar,
stringers, etc.) to try and find the leak. D - cutting access holes in
the bottom wing skin all the way around the tank so that I can find the
leak. Given those options, if anyone can suggest a sloshing compound
that they have used regularly with aviation fuel and auto fuel, I'll
wimp out and opt for B.
2. Right wing has a good sized leak that I can't plug from the outside.
I have pulled off the access panel I put in the center bay and I'll
build a fortress of pro-seal around the area of the leak.
I have restored 5-6 airplanes, but between the bungees and the pro-seal,
this has been the most challenging. I am still excited to fly this
bird!
