Thanks for the soap responses everyone.  Is it  possible to do a good test without removing the tanks from the wings?  Mine  are soooo nice and snug right now.  ???????

 Thanks for letting me continually pick your  brains.

Dave,  

   

You can test for leaks around the rivets and inboard rib without removing the tanks from the wings, but you will miss the entire rear bulkhead and outboard rib.  It is a risk, but if you do the balloon test and test for air bubbles around everywhere you can see, then wait to see if the balloon holds air, then you may be OK.  As Tim mentioned, it is best to do the balloon and soap together, but if the balloon holds air for 24 hours (it may grow or shrink a little with changing temperatures), then you should have a good seal.  Just make sure that you have a good seal around all of the fittings that you “block off”, because you could have a leak around one of those and think the tank is bad when it is not bad.  

   

Do not archive

Dave,



I removed one tank in order to install the stall warning. It isn´t a big deal, however be carful unscrewing the tank screws on the skin because the are quite soft and I had to drill one out.
