Any advice to a builder that's just starting the tanks?
Fuel leaks out through unsealed rivet holes and baffle joints.

Use lots of sealant to encapsulate rivet heads and rib joints, especially the fluted rib flange edges and when setting the aft baffle, do not skimp on sealant.

Think - where could fuel possibly leak out - put a glob of sealant over it.

I totally agree with David. Don't skimp on sealant. I used almost 1 qt per tank on my -10's 30 gallon tanks. I then coated all joint areas red buna-n sealant from ACS. Tested to 1 psi. No leaks so far.
