I leak checked mine with a balloon but it kept deflating. I fixed all the leaks I could find with soapy water. I put some fuel in it, capped it off and put it in the sun and within 20 minutes I starting seeing fuel weeping from quite a few rivets in the skin to baffle area. I now pass the balloon test and the fuel test.

I'm thinking that the most likely place for the tanks to leak would be the rear of the tank.
So why not put the tank on a table with the leading edge facing up, and put about a gallon of fuel in the tank? That should be enough for 1/2 to an inch of fuel on the bottom.
Has anyone done this? Is there any reason NOT to do this? I just don't trust the balloon test. There's too many places for air to leak out like the fuel caps and the balloon itself.
I would hate to 'think' the test is good, bolt the tanks on, paint the wings, and the find out there is a small leak somewhere!
Thoughts??
