I didn't either. The gap was pretty large, and I don't think a Hysol bridge across that gap really does anything for you except make it hard to rib stitch. If Josh's fuel tanks fly out when he flies his plane (You are going to fly it, right Josh?), maybe I'll re-think it.
Re: Rib stitching problem
I installed my tanks more to the outboard side to give more room for the fittings on the inboard side. That made the tank-to-rib gap pretty narrow on the outboard side, and quite wide on the inboard side. So I only filled the outboard gap with Hysol (and drilled it for rib stitching).
Re: Rib stitching problem
My tank to rib gap is about 1/4 inch.I assume there is no hysol,as there is a lot of flexing between the two which has caused the paint to start failing.
A bridged joint would possibly eliminate this.
Re: Rib stitching problem
My tanks were not square, and I had to do some trimming on the right tank to get it to fit in between ribs 1 and 3. The hysol bridge is about 5/16” on the outboard side of the tank. The tanks also had some twist to them so they rocked a bit. The hysol is pretty hard, so I decided to drill through the top and bottom of the tanks to allow rib stitching, instead of drilling through the hysol to save time. This is going to be awesome.
Re: Rib stitching problem
I did the same as Jim and for the same reasons.

Just slosh your tanks, that should take care of any leaks. :D
Re: Rib stitching problem
You need to pressure test the tanks if you actually drilled through the flange. It would have been better to drill the Hysol.....

Sarcasm nugget of the week!
Re: Rib stitching problem
Sloshing the tanks after they are installed in the wing might seem like a daunting task. There may have been a thread discussing attaching a washing machine motor to a wing rotisserie to make the job easier. An advance thread search might be required.
