|
|
During my annual inspection I noticed a little blue star-like stain around one rivet on the right of the lower fuel tank. After a cleaning, sure the blue stain was there again.
No, it does not drip, just the stain.
What is the best way to seal this seep??

I have heard of others creating a slight vacuum in the tank and then adding
some thinned down proseal. Would have to be pretty clean to start with.
Others will have better details

Your approach will depend on where the offending rivet is. If it is one
of the rear baffle-skin rivets, I'd suggest taking the whole tank off
the plane, drilling out the offending rivet (and several either side of
it) and cleaning out and re-riveting the hole with more proseal. If
it's a rib rivet that can be gotten to through the inspection hole, then
try re-sealing it with more proseal. If you cannot get to it, then try
the thinned proseal/ vacuum trick.
One thing to be aware of is that tank leaks are lie roof leaks. Fuel
can get below the proseal in one place and come out a rivet several
inches away. Just because water is leaking into your kitchen, it could
be entering the roof some distance away. Same idea.

I had a similar problem on my RV-4. The seeping rivet was on the bottom.
My solution was to drain the tank, drill out the bad rivet and replace with
one of Van's sealed blind rivets with a dab of proseal on it just before
installation. No seeping after 2 years and 250 hours.

A quick easy and cheap way to fix it with Click Bond repair patch.
I put one on my tank several years ago and it hasn't leaked a drop since.

I used thinned proseal on one rivet that leaked air when I pressure

tested. You do have to be careful not to use too much vacuum or leave it
applied too long or it will suck a 'hole' in the new sealant.
Mooney drivers have had luck with a wicking sealer (not sure of what
they use; might be the Locktite mentioned below), pulled in with a
slight vacuum like described earlier for thinned proseal.
I haven't used it, but others have said they had good luck with Locktite
Green wicking thread lock.
Good luck...

Good Morning,
This approach worked very well for me, too.

Doug,
How did you deal with the drilled out rivet shop head and (possibly) loose drill shavings that must have fallen into the tank?

The technique is to use a 3/32 bit and partially drill into the rivet to the
point where you can then snap off the head using a 3/32 pin punch. Then
using the punch I tapped into the rivet to the point where the shop portion
of the rivet fell out (into the tank). Granted now that small part was in
the tank and it actually stayed there for quite some time. Later, I had to
remove this tank anyway because of a leaking root cover and that little
piece was still there just laying in the bottom inboard part of the tank. I
then removed it. I suppose that might have been the downside to this
method, but no harm done.
